Best Led Side Marker Lights for Trailers, RVs, and Trucks

#1 · Best Overall

1. Nilight 3.8 Inch Amber Lights

• Voltage: 12 V
• Wattage: 5 W
• Compatible with Vehicle Type: Golf Cart, RV, Tractor, Truck

Best for: Ten-piece sealed amber installations.

Why it ranks #1: Ten lights provide a useful set quantity, and each has six 2835 SMD LEDs with a stated 120-lumen output and sealed wire lead.

Ten amber lights, each producing a listed 120 lumens from six high-intensity 2835 SMD LEDs, provide a substantial matching set for marker replacement or installation. Nilight adds sealing at the front lens and wire lead, making this 12-volt surface-mount option relevant to RV, tractor, truck, and golf-cart owners seeking multiple amber fixtures.

The six-LED layout is rated at 120 lumens per light, giving buyers a consistent output across all ten included markers. Sealing at both the lens and wire lead addresses two points on the fixture, while the two-wire connection uses yellow for positive and black for negative. That defined wiring setup helps clarify installation, and the 12-volt rating matches the listed vehicle types. The 3.8-inch lights are all amber, so this is a uniform-color kit.

Skip it if you need red and amber markers together; Tallew 10 Pcs 2.5 Inch LED Trailer Side Marker Lights includes both colors.

This set suits buyers replacing or adding multiple amber markers on a 12-volt RV, tractor, truck, or golf cart. Its ten matching lights simplify uniform-color planning, but it is not a mixed-color assortment.

#2 · Best Mixed Colors

2. Partsam Double Bullseye Lights

• Voltage: 12 V
• Wattage: 6 W

Best for: Two-color trailer marker setups.

Why it ranks #2: The 14-light set includes seven amber and seven red lamps, is listed as DOT approved, and supports side-marker and clearance use.

A two-color set of seven amber and seven red double-bullseye lamps gives trailer owners matching lights for different marker positions. Each 4-by-2-inch, 12-volt surface-mount fixture can serve as a side marker, clearance lamp, or identification lamp, making the set useful across RVs, trailers, campers, and boats.

The amber-and-red assortment supports color-specific placement, while the double-bullseye format provides a distinct lens style in a broad 4-by-2-inch footprint. Surface mounting suits installations where a rectangular fixture can sit on the vehicle exterior, and the stated 12-volt power matches the listed vehicle applications. One wiring detail matters before planning the mount: the product information warns that wires exit from the center, so the route behind the light needs to accommodate that position.

Skip it if you need an amber-only set; Partsam 2Pcs 4 Inch LED Trailer Lights supplies two amber fixtures.

Choose this set for a 12-volt trailer, RV, camper, or boat needing both amber and red surface-mounted markers. Its rectangular 4-by-2-inch footprint and center wire exit are important considerations for placement.

#3 · Best Built-In Reflector

3. Partsam Reflector Rectangle Lights

• Voltage: 12 V

Best for: Reflector-integrated amber markers.

Why it ranks #3: Two amber 4-by-2-inch lights have six LEDs each, a built-in reflex reflector, replaceable snap-on lenses, and listed DOT approval.

A built-in reflex reflector combines reflective visibility with six amber LEDs in each 4-by-2-inch fixture, eliminating the need for a separate reflector at that location. This two-light Partsam set suits 12-volt trailers, RVs, pickups, vans, and boats needing amber side, front, rear, or identification markers.

The integrated reflex reflector combines two functions in one surface-mounted housing, which can simplify a location that would otherwise use a separate reflector. Each lamp has six LEDs and a replaceable snap-on lens, so lens replacement does not require replacing the whole light. The white base and two-wire connection define the installation setup, while the 12-volt rating supports the listed vehicle types. Its amber-only pair is suited to positions calling for amber markers.

Skip it if you need both lens colors in one set; Partsam 14x Trailer RV Marker LED Light includes amber and red lamps.

This pair fits buyers adding amber front, rear, side, or identification markers to a 12-volt vehicle and wanting a reflector integrated into each light. Consider the amber-only color selection when planning a mixed-color installation.

#4 · Best Aluminum Housing

4. Partsam Aluminum Housing Lights

• Voltage: 12 V
• Compatible with Vehicle Type: Trailer, Truck, Motorcycle, Golf Cart
• Lens Material: Polycarbonate

Best for: Aluminum mixed-color marker upgrades.

Why it ranks #4: Four red-and-amber lights use aluminum alloy bases, polycarbonate lenses, and an IP67 waterproof rating for listed 12V applications.

An aluminum-alloy base, rather than a plastic base, gives these four Partsam lights their defining construction feature, with the product listing better heat dissipation as a benefit. The set contains two red and two amber 3.4-inch fixtures, each with four LEDs, an IP67 waterproof rating, and a 12-volt fit for several vehicle types.

The aluminum-alloy base is specified to improve heat dissipation, while the polycarbonate lens offers listed impact resistance and transparency. Together, those materials make the construction a central consideration for buyers selecting markers for exposed vehicle locations. Four LEDs per light and an IP67 rating support the listed bright, waterproof use. The slim surface-mount format can be installed in a range of locations, and the two-red, two-amber mix supports color-specific placement on 12-volt trailers, trucks, tractors, motorcycles, or golf carts.

Skip it if you need ten amber fixtures for a larger installation; Nilight 3.8 Inch 6 LED Amber Trailer Side Marker Lights,10 Pack supplies ten.

This set suits buyers replacing four 12-volt markers and wanting both colors, an aluminum-alloy base, and IP67 protection. Its four-light quantity and slim surface-mount format should fit the planned locations.

#5 · Highest Capacity

5. TMH Bullet Marker Lights

• Voltage: 12 V DC

Best for: Compact mixed-color marker kits.

Why it ranks #5: A 20-piece assortment supplies 10 amber and 10 red 3/4-inch lights, each listed at 60 lumens with a rubber cover.

Twenty miniature 3/4-inch bullet lights—ten amber and ten red—give installers a large mixed-color supply in a compact format. Each 12-volt light uses three SMD LEDs and is listed at 60 lumens, making this TMH set a practical option for trailers, trucks, cars, buses, or vans where small round markers suit the mounting locations.

The 3/4-inch round bullet size can suit mounting spots where a larger rectangular marker would not fit, while the 20-piece assortment supplies ten lamps of each color for distributed installations. Three SMD LEDs produce a listed 60 lumens per light. The supplied rubber covers support the installation, and the PC lenses are described as waterproof, shockproof, and dustproof. These compact 12-volt lights suit buyers planning multiple marker positions rather than a small two-light replacement.

Skip it if you need broad rectangular fixtures; Partsam 14x Trailer RV Marker LED Light offers 4-by-2-inch lamps.

Choose this kit for a multi-position 12-volt installation that calls for many small round amber and red markers. Its miniature 3/4-inch format is the key fit consideration, especially when replacing larger existing lights.

#6

6. Tallew 2.5 Inch Lights

• Voltage: 12 V
• Wattage: 5 W
• Compatible with Vehicle Type: Boat, Car, Trailer, Truck
• Lens Material: Plastic

Best for: Mixed-color screw-mounted sets.

Why it ranks #6: Ten surface-mount lamps split evenly between red and amber, and the package includes two stainless steel screws per light.

Five amber and five red 2.5-inch lights give this Tallew kit a balanced color mix for multi-position trailer marker work. Each fixture comes with two stainless steel mounting screws, and its 12-volt wiring uses red as positive and black as negative, offering a clearly specified setup for trailer, truck, boat, or car installations.

The five-and-five color split helps buyers assign amber and red markers across a vehicle without sourcing separate color packs. At approximately 2.59 by 1.1 inches, the lights have a compact rectangular footprint, and the included stainless steel screws support surface mounting. Center-exiting wires affect how each light sits against its mounting surface, so plan the wire route before fastening. The stated 12-volt supply and waterproof designation suit the listed vehicle applications.

Skip it if you need six LEDs and a built-in reflector; Partsam 2Pcs Amber 4 Inch LED Trailer RV Camper Side Marker Lights combines them.

This set suits buyers installing several mixed-color markers on a 12-volt trailer, truck, boat, or car. The compact footprint and included screws are useful, but the center wire exit should guide mounting placement.

#7

7. PSDRIQQ 2.5 Inch Lights

• Voltage: 12 V DC
• Wattage: 5 W

Best for: Twenty-light broad-voltage kits.

Why it ranks #7: The 20-piece amber set includes 40 screws and is described for DC12–24V vehicles, though each lamp has only two LEDs.

A stated DC12-24V universal fit range sets this 20-piece PSDRIQQ kit apart for buyers working across compatible vehicle voltages. The assortment includes twenty amber lights and forty screws, with two LEDs in each lamp, giving RV, trailer, truck, van, boat, and other listed vehicle owners ample fixtures for distributed marker placement.

Two LEDs in each of the twenty lamps provide a consistent small-light configuration across a broad installation, while the included forty screws supply mounting hardware for the full set. The listed DC12-24V fit range covers more than a single 12-volt rating, which can help buyers planning around compatible vehicle electrical systems. The lights can function as front, rear, side, or clearance indicators. All fixtures are amber, a key constraint when assigning positions that require another color.

Skip it if you need mixed-color fixtures and aluminum housings; Partsam 4Pcs 3.4 inch Aluminum Housing Red/Amber LED Clearance Side Marker Lights has both.

Choose this kit for a broad marker installation needing many amber fixtures and supplied screws across listed DC12-24V vehicles. Its one-color assortment is the main fit boundary for buyers planning red positions.

#8

8. TRUE MODS Rectangle Lights

• Voltage: 12 V
• Wattage: 1 W
• Compatible with Vehicle Type: Boat, Trailer, Truck
• Lens Material: Acrylic

Best for: Boat-trailer reflector combinations.

Why it ranks #8: Two amber rectangle lights combine a marker and reflector, with listed IP67 protection for trailer, truck, and boat use.

Combining an amber side marker with a reflector lets these two TRUE MODS lights handle both functions at one mounting location. Their IP67 rating supports use on boat as well as work trailers, while the 12-volt, acrylic-lens fixtures suit buyers seeking a paired rectangular marker-and-reflector solution rather than separate reflective tape and lights.

The integrated reflector can remove the need to source reflective tape separately at the marker position, streamlining the parts list for a trailer installation. IP67-rated construction is specified for both boat and work-trailer use, so the pair serves applications where water exposure is a consideration. The 12-volt rating matches the listed truck, trailer, and boat compatibility. Top markings are also noted in the product information, offering an installation reference without changing the dual-function role.

Skip it if you need a mixed red-and-amber set; Partsam 4Pcs 3.4 inch Aluminum Housing Red/Amber LED Clearance Side Marker Lights includes both colors.

This pair suits boat or work-trailer owners who want an amber marker and reflector combined at each location. Check that the 12-volt supply and amber color suit the intended positions before choosing it.

9. CZC AUTO Sealed Lights

• Voltage: 12 V
• Compatible with Vehicle Type: Boat, Car, Trailer, Truck
• Lens Material: Acrylic

Best for: Submersible amber trailer markers.

Why it ranks #9: The two amber lamps have four LEDs each, sonic-sealed ABS housings, an IP68 rating, and four mounting screws.

An IP68 waterproof rating and sonic-sealed construction distinguish these two CZC AUTO amber markers for installations exposed to water. Each light has four LEDs—two more than the product’s stated comparison with similar lights—and the kit includes four mounting screws, making it a focused option for trailer, boat, truck, or car marker replacement.

The sonic-sealed ABS housing and PMMA lens are specified as submersible to IP68, a relevant feature for buyers mounting markers where water exposure is a concern. Four LEDs per light provide the listed light configuration, while the included four screws support installation of the two lamps. The lights can serve as side markers, clearance lamps, reflectors, or trailer running-light replacements. Their amber color and 12-volt rating help define where they fit in a vehicle lighting plan.

Skip it if you need twenty lights for a broad installation; PSDRIQQ LED Trailer Lights Kit includes twenty amber fixtures and forty screws.

Pick this pair for amber trailer or boat markers where the IP68 submersible rating is relevant and only two fixtures are needed. Its amber-only selection and two-light quantity set clear boundaries for larger jobs.

#10

10. Nilight 3.9 Inch Amber Lights

• Voltage: 12 V DC
• Wattage: 30 W
• Compatible with Vehicle Type: Bo, Bus, SUV, Trailer, Truck
• Lens Material: Acrylic

Best for: Two-light amber replacements.

Why it ranks #10: Two amber lights suit listed 12V vehicles and include a reflector design, but the two-piece quantity is less useful for larger replacements.

Three Piranha LEDs per light are specified for improved heat dissipation, wider lighting angle, and higher light intensity, giving this two-piece amber set its defining feature. Nilight lists the 3.9-inch fixtures for front, rear, side, or roof marker use on 12-volt pickups, trailers, SUVs, RVs, vans, campers, boats, and buses.

The three Piranha LEDs and reflector design combine direct lighting with a reflective element, supporting marker use across several positions on a vehicle. Nilight lists a 30mA lighting amperage per light and a 12-volt direct-current supply, details useful when planning the electrical connection. The pair provides a smaller replacement quantity than a multi-light kit, and the acrylic lens and waterproof designation suit buyers selecting lights for listed trailer and vehicle applications.

Skip it if you need ten matching amber markers at once; Nilight 3.8 Inch 6 LED Amber Trailer Side Marker Lights,10 Pack supplies ten.

Choose this pair for a 12-volt vehicle needing two amber markers with a reflector design, whether placed at the front, rear, side, or roof. The two-light quantity is the main boundary for larger installations.
