Best Wig Wag Lights For Trucks: Compare Relays and Strobe Lights

#1 · Best Overall

1. Stop-Alert WigWag 36

• Wattage: 120 W
• Voltage: 24 V

Best for: Programmable headlight wig-wag.

Why it ranks #1: A dedicated alternating flasher with 36 selectable patterns, two 10-amp outputs, and stated compatibility with headlights, LEDs, and other lamps.

Thirty-six selectable patterns and listed headlight compatibility make the Stop-Alert WigWag 36 a controller for drivers seeking more than a basic alternating flash. Its two outputs provide up to 10 amps each, while integrated LEDs and a programming switch let the operator select and set a preferred pattern.

Unlike a lamp kit, this unit controls compatible headlights, LEDs, and other lamps, so it suits a vehicle with lights already in place. The 36-pattern selection supports choosing a signal for the application, and the programming switch provides a direct way to change modes. Two 10A outputs and a stated 240W maximum load define the electrical planning limits. Its sealed aluminum enclosure is described as waterproof, relevant for vehicle-mounted use in wet conditions.

Skip it if you need a prepackaged set of strobe lamps rather than a controller; the BooYu Y017-WY includes eight lights.

For truck owners adding programmable wig-wag control to compatible headlights or other lamps, this relay offers substantial pattern choice and defined output limits. It is a controller, not a complete light kit, so existing lamps are needed.

#2 · Best Auxiliary Relay

2. Stop-Alert X2 Wig Wagger

• Wattage: 72 W
• Voltage: 24 V

Best for: Alternating auxiliary-light control.

Why it ranks #2: Provides an alternating wig-wag pattern on 12–24V systems with 36W per channel, but its disclaimer says it is not for headlights.

An alternating wig-wag pattern is the defining feature of the Stop-Alert X2 controller, enabling compatible auxiliary lights to flash in turn rather than as a steady signal. Its 72W total load rating, specified as 36W per channel, supports a two-channel setup across listed 12V–24V systems.

This is a relay controller rather than a packaged set of lamps, so it is suited to buyers who already have compatible lights and need alternating control. The 36W-per-channel rating gives a clear load limit for planning the connected setup, while the 12V–24V range covers the listed vehicle-system voltages. Its waterproof design addresses exposure concerns, but the supplied legal notice specifically excludes headlight lamps, making auxiliary-light use the appropriate boundary.

Skip it if you want a controller for headlights; the Stop-Alert WigWag 36 explicitly lists headlight compatibility.

Choose this controller if your truck already has compatible auxiliary lamps and you want alternating flashes within its 36W-per-channel rating. It is not the right choice for headlight lamps, so plan around that stated restriction.

#3 · Most Flash Patterns

3. WINECO LED Strobe Kit

• Wattage: 96 W
• Voltage: 24 V

Best for: Multi-pattern surface-mount kit.

Why it ranks #3: Eight surface-mount lights and a controller offer 30 patterns, memory, and a listed 12/24V application for truck warning-light setups.

Thirty selectable strobe patterns give the WINECO eight-light kit flexibility to tailor warning flashes for a truck, ATV, RV, or other listed vehicle. Its amber-and-white combination and memory function let drivers choose a preferred signal and have the selected pattern recalled when the lights are used again.

Eight surface-mount lights provide a distributed warning setup, while the listed 12V/24V vehicle compatibility covers a range of vehicle electrical systems. The aluminum construction and weatherproof exterior-mounting description support use on exposed vehicle locations. A controller offers power and mode switches, and the built-in fuse and voltage regulator chip are listed electrical features. With 30 patterns and memory, operators can select a signal and avoid resetting their preferred mode each time.

Skip it if you need a controller explicitly rated for headlight use; the Stop-Alert WigWag 36 lists headlight compatibility.

This kit suits truck and utility-vehicle owners wanting multiple exterior-mounted amber-and-white warning lights and a broad choice of patterns. Check the stated voltage information against your vehicle and installation plan before choosing it.

#4 · Weatherproof Surface Kit

4. ASPL Ultra Slim Strobes

• Wattage: 12 W
• Voltage: 24 V

Best for: Slim aluminum warning lights.

Why it ranks #4: Eight 12-LED surface lights have an aluminum housing, stated IP67 waterproofing, and pattern recall for a fixed exterior installation.

An ultra-slim surface-mount form pairs with aluminum housings in the ASPL eight-light kit, helping buyers place warning lamps where a low-profile mounting style is useful. Each light has 12 high-intensity LEDs, and the listed pattern-recall feature lets the selected flash mode carry over between uses.

Eight 12-LED lights provide multiple mounting points, while the aluminum housing and ABS magnifying lens are described as supporting brightness. IP67 waterproofing and the stated 50,000-hour lifespan address weather exposure and expected operating life, useful considerations for exterior vehicle lighting. The product lists 24V in its specifications, so buyers should use that stated voltage when planning their installation. Pattern recall helps retain a chosen signal instead of requiring mode selection each time.

Skip it if you need an explicitly listed 12V kit; the HLauto CA-6Z4J AW-WA dash bars specify 12 volts.

Consider this kit for a 24V installation needing several low-profile surface-mount lights and listed weather protection. Its specification states 24V, making voltage suitability the key boundary for a truck-lighting plan.

#5 · Synchronized Kit

5. BooYu Sync Strobe Kit

• Voltage: 12 V DC
• Lens Material: Polycarbonate

Best for: Mixed-row synchronized light kit.

Why it ranks #5: Eight lights combine single- and double-row units, with 12 modes, synchronization, memory, and stated compatibility with trucks and several other vehicles.

Four single-row and four double-row lights give the BooYu kit two lamp formats in one eight-piece amber-and-white setup. Its controller offers 12 flash modes, including synchronized and alternating options, enabling buyers to configure a coordinated warning display across the listed truck and utility-vehicle applications.

The combination of four 12-LED single-row lights and four 24-LED double-row lights provides different light formats for arranging a vehicle installation. A two-button controller makes mode selection the stated operating method, while 12 patterns include pulsing, alternating, synchronized flashing, and steady illumination. Memory recalls the last pattern, reducing repeated mode selection. The kit is listed for 12V DC and a broad range of vehicles, including trucks, buses, RVs, and UTVs.

Skip it if you need a kit explicitly listed for 24V operation; the WINECO WX501S-8 lists 12V/24V vehicle compatibility.

This is a good fit for 12V truck or utility-vehicle owners who want mixed light formats and coordinated pattern choices. Its stated voltage is 12V DC, so that specification should guide installation selection.

#6

6. EASE2U Surface Strobes

• Wattage: 6 W
• Voltage: 12 V
• Lens Material: Polycarbonate

Best for: Ten-light 12V installations.

Why it ranks #6: The 10-piece kit includes mounting screws and protection pads, with seven patterns and memory; listed vehicle compatibility includes trucks.

Ten synchronized 12-LED strobe lights make the EASE2U E kit a high-count option for buyers who need warning lamps across several mounting points. Seven flash patterns and last-pattern memory provide operating choice, while the included protection pads and mounting screws support a more complete installation kit.

The ten lights and ten protection pads let an installer plan a multi-point vehicle layout without sourcing those listed pieces separately. Each unit is specified at 12V, and the product lists compatibility with trucks, cars, and ATVs, which helps define its electrical and vehicle scope. Seven patterns with memory allow a selected flash mode to be recalled. Waterproofing is also listed, supporting use in exposed vehicle locations; installation still requires the stated wire connections.

Skip it if you need a kit specified for 24V; the WINECO WX501S-8 lists 12V/24V vehicle compatibility.

This kit fits 12V truck, ATV, or car owners planning multiple warning-light positions and wanting included mounting pieces. Its 12V specification is a firm electrical boundary, so it does not suit a 24V-only plan.

#7

7. HLauto Dash Strobe Bars

• Wattage: 20 W
• Voltage: 12 V
• Lens Material: Polycarbonate

Best for: Windshield-mounted dash bars.

Why it ranks #7: Two 16.8-inch bars use 48 LEDs and include adjustable brackets, suction cups, and a long cable for windshield or rear-window placement.

Two 16.8-inch bars with 48 high-brightness LEDs provide the HLauto dash kit’s defining windshield-warning setup. Adjustable brackets, ten suction cups, and a 13.12-foot cable enable placement on a front windshield or rear window, giving truck owners a mounting approach distinct from surface-mounted grille lights.

The pair of bars and adjustable brackets support positioning the lights at a window, while the supplied suction cups provide the listed attachment method. A 13.12-foot cable gives the installation reach described in the product information. The 12V specification and truck compatibility help define the electrical and vehicle scope. Waterproofing is listed, and the 48 LEDs with upgraded 4D lenses are described as brighter than 32-LED bars, supporting a high-visibility dash format.

Skip it if you need compact grille-mounted lights instead of window bars; the HLauto 406T-AW is a four-piece surface-mount grille kit.

This suits truck drivers seeking a window-mounted warning setup with adjustable brackets and a long cable. Choose it for windshield or rear-window placement, not when your installation calls for individual grille-mounted lamps.

#8

8. HLauto Grille Strobes

• Lens Material: Polycarbonate

Best for: Four-piece grille warning kit.

Why it ranks #8: Four surface-mount grille lights offer 17 flashing patterns and list compatibility with trucks and several work vehicles.

Seventeen flashing patterns give the HLauto four-piece grille-light kit substantial signal choice in a compact surface-mount arrangement. Its listed applications include trucks, snowplows, tractors, UTVs, school buses, and other work vehicles, making it relevant to buyers equipping varied service and safety vehicles.

Four lights provide a defined set for a grille installation, while the 17 patterns allow operators to choose among multiple warning displays. The product lists polycarbonate lenses and amber-and-white coloring, helping identify its lens material and signal colors for planning. Compatibility spans trucks and several work or utility vehicle types, including snowplows and school buses. The supplied specifications do not state a voltage or detailed mounting hardware, so installation planning should account for those missing details.

Skip it if you need stated 12V dash-bar specifications; the HLauto CA-6Z4J AW-WA provides a listed 12V window-mounted option.

This kit suits work-truck and utility-vehicle owners seeking four grille lights with many pattern choices. The supplied specifications omit operating voltage, so that unresolved electrical detail is a key installation boundary.

#9

9. Tallew LED Strobe Lights

• Voltage: 24 V

Best for: High-count fleet light kit.

Why it ranks #9: The 20-piece amber-white set has aluminum housings and PC lenses, but its listed modes are constant and strobe rather than alternating wig-wag.

Twenty amber-and-white LED strobe lights make the Tallew kit suited to installations needing many warning-light positions from one pack. Each light offers constant and strobe modes, while aluminum-alloy housings and waterproof construction address durability and exposure considerations for vehicle use.

The 20-piece count is the main practical advantage for buyers planning multiple vehicle positions or more than one installation. Its two listed modes—constant and strobe—keep operation straightforward, though offer less stated pattern choice than kits with multiple flash programs. Aluminum alloy housing is described as supporting heat dissipation, and the PC lens provides protection. The product lists 24V and a compact 4.41-by-1.1-by-0.2-inch size for each light.

Skip it if you want numerous selectable flash patterns; the WINECO WX501S-8 lists 30 patterns and memory.

Choose this pack for a 24V truck or fleet installation where a high light count and two basic operating modes meet the need. Its mode selection is limited to constant or strobe, rather than a long pattern menu.

#10

10. Buyers Products Raised Strobe

• Voltage: 12 V
• Lens Material: Plastic

Best for: Rugged raised amber beacon.

Why it ranks #10: This single amber 5-inch raised beacon is IP67 and SAE J595 Class 2, but it is a warning strobe rather than a wig-wag relay or multi-light kit.

SAE J595 Class 2 brightness certification distinguishes the Buyers Products raised five-inch amber LED warning light, helping work-vehicle operators choose a light with a stated performance classification. Its heavy-duty aluminum construction and IP67 water-and-dust resistance suit the demanding outdoor environments described for work trucks and roadside equipment.

The raised five-inch format provides a single warning light rather than a multi-lamp kit, making it a focused option for work trucks, trailers, service vehicles, and roadside equipment. Aluminum construction supports durability in tough work environments, while IP67 protection addresses water and dust exposure. SAE J595 Class 2 certification supplies a defined brightness classification. It is specified for 12V and listed for trucks, buses, tractors, ATVs, and UTVs, helping define electrical and vehicle fit.

Skip it if you need several grille lights in one kit; the HLauto 406T-AW includes four surface-mount lights.

This raised amber light fits 12V work trucks and roadside equipment needing a single rugged warning point with a stated brightness class. Its one-light format is the boundary for buyers planning distributed vehicle coverage.
