Best Wig Wag Headlight Flasher Kit for Vehicle Lighting

#1 · Best Overall

1. Whelen SSFPOS Flasher

• Voltage: 12.8 V

Best for: Waterproof 12.8V vehicle circuits.

Why it ranks #1: Specifically titled a headlight grille light flasher, it lists 12.8 volts, 160 watts, a high-side design, and a waterproof feature.

A stated 160-watt capacity and waterproof feature define the Whelen SSFPOS solid-state flasher’s headline specifications. It operates at 12.8V and is identified for car use, giving buyers a voltage and load reference when considering a headlight or grille-light flasher installation.

The 160-watt rating provides a concrete capacity figure for planning a compatible lighting circuit, while the 12.8V specification identifies the operating voltage to match. Its waterproof feature is relevant for a vehicle-mounted flasher, and the title identifies headlight and grille-light use. The supplied facts do not describe flash patterns, connections, or installation steps, so buyers should treat those as unresolved details rather than infer a particular wiring workflow.

Skip it if you need selectable patterns and a steady-on mode; the ADS SHO 2015 lists 15 patterns plus steady on.

The Whelen is suited to buyers seeking a waterproof flasher identified for headlight or grille-light use on a 12.8V car circuit. Its load rating helps planning, but pattern and connection details are not supplied.

#2 · Best 12–24V Option

2. Stop-Alert WigWagger 72

• Voltage: 24 V

Best for: 12–24V auxiliary-light operators.

Why it ranks #2: The listing describes alternating warning lights, waterproof construction, 12–24V compatibility, and 36 watts per channel for vehicle lighting.

A 36-watt-per-channel circuit gives the Stop-Alert WigWagger 72 a defined capacity for alternating auxiliary lights, with 72 watts of total load. Its 12–24V range covers more system voltages than a 12V-only relay, while the waterproof design suits buyers seeking an emergency warning-light controller for a car, truck, or motorcycle.

The alternating wig-wag pattern makes paired lights flash in turn, supporting the visibility role described for warning use. Its 36 watts per channel and 72-watt load rating give buyers a concrete capacity reference when matching auxiliary daytime-running or strobe lights. Operation across 12–24V broadens electrical-system compatibility, and the waterproof design is a practical feature for a controller used on a vehicle. This is specified for auxiliary lights; the listing does not establish headlight-lamp compatibility.

Skip it if you need a flasher explicitly identified for headlamps; the Stop-Alert X2 listing also says it is not for headlights.

A buyer wiring compatible auxiliary warning or daytime-running lights on a 12–24V vehicle can consider this relay for alternating output. Its stated role is auxiliary lighting, so headlight-lamp use is a boundary to observe.

#3 · Most Pattern Choices

3. ADS SHO 2015 Flasher

• Voltage: 12 V

Best for: 12V multi-pattern LED users.

Why it ranks #3: Designed for 12V LEDs, it offers 15 flash patterns plus steady-on mode and separate left and right sides with multiple leads.

Fifteen selectable flash patterns plus a steady-on mode give the ADS SHO 2015 more operating choices than a single-pattern flasher. Its left and right sides each offer three leads, and the listing states support for eight to ten 1-watt LEDs on each lead in a 12V setup.

The built-in momentary switch changes among the 15 patterns and steady-on mode, allowing the user to select the output behavior without relying on a fixed sequence. Three leads on each side provide multiple LED connection points, with the stated eight-to-ten 1-watt LEDs per lead giving a concrete configuration reference. This is specified for 12V operation, so it fits buyers planning around that system voltage rather than a broader 12–24V range.

Skip it if you need a stated 12–24V range; the Stop-Alert WigWagger 72 supports that voltage span for auxiliary lights.

The ADS suits a 12V buyer who wants pattern choice and multiple LED leads on each side. Its listed LED capacity and switch-based pattern selection help define the setup, while the 12V specification is the main fit boundary.

#4

4. Amperite 15-Amp Flasher

Best for: 15A solid-state relay shoppers.

Why it ranks #4: Its title specifies solid-state analog wig-wag circuitry rated at 15 amps, though the listing supplies little else about voltage or lamp compatibility.

A 15-amp rating is the key stated specification of the Amperite wig-wag flasher. Its solid-state analog circuitry identifies the switching approach, making it a simple option to evaluate when the required capacity is within that rating. The supplied listing provides no voltage or timing details, so those points cannot guide selection.

The title specifies both wig-wag operation and 15 amps, giving buyers two concrete checks when considering it for an alternating-flasher circuit. Solid-state analog circuitry distinguishes its construction from a programmable timing module, but the supplied information does not describe adjustable patterns, voltage range, wiring, or load types. That limited specification set makes it important to base a decision only on confirmed compatibility and the 15A rating, rather than assuming broader vehicle or lamp support.

Skip it if you need a stated voltage range or adjustable timing; the URANT DC 4.5–30V module specifies both.

This is a candidate for a buyer whose circuit needs a 15A wig-wag flasher and whose installation requirements are confirmed independently. The sparse listing leaves voltage, wiring, and timing unspecified, so those are key fit boundaries.

#5 · Adjustable Timing

5. URANT Adjustable Flasher

Best for: Custom-timing module users.

Why it ranks #5: This dual-output module operates from 4.5–30V and allows separate output timing from 0.01 to 15 seconds, but is not headlight-specific.

Dual independent timing potentiometers let the URANT module set separate on-times for its two outputs, from 0.01 to 15 seconds. That range enables adjustable, including asymmetrical, alternating flash patterns rather than a fixed wig-wag rhythm. Its 4.5–30V DC input range also spans a wider voltage window than a 12V-only module.

Each output’s on-time can be adjusted independently, so buyers can shape the timing of the two sides instead of relying on a single shared setting. The stated 0.01-to-15-second range supports both short and longer intervals. A 4.5–30V DC operating range gives flexibility across compatible low-voltage setups, while the listed 10A-per-channel capacity provides a load reference when planning the lamps. This is a module for various warning lights; installation details are not supplied.

Skip it if you want a ready-to-connect vehicle relay with stated wiring details; the Generic 3-prong 12V relay describes its switched input and lamp outputs.

Choose this URANT module if you need independently adjustable alternating timing and your setup fits its DC voltage and channel limits. Buyers wanting specified plug-style wiring or headlight-specific fitment will need details not provided here.

#6 · Dual-Output Capacity

6. OONO F-1053 Flasher

Best for: Adjustable dual-output lamp circuits.

Why it ranks #6: It lists 4.5–30V operation and up to 10 amps per output, with adjustable timing for LED lamps and other warning-light loads.

Separate duration controls for OUT-1 and OUT-2 let the OONO F-1053 tailor each side of an alternating pattern. Its 4.5–30V DC operating range and 10A-per-output rating make the module applicable to a range of compatible lamp circuits, including the listed LED lamps, hazard lights, warning signs, and beacons.

Independent output timing allows the two lamps or sides to alternate with separately chosen durations, a useful option when a fixed symmetrical flash is not the desired behavior. The 4.5–30V input range provides flexibility for compatible DC systems, while 10A maximum current per output gives a clear channel limit. The listing also names resistive and slightly inductive loads, including bulbs and LED lamps. Buyers should plan around those stated limits and the module’s manual control mode.

Skip it if you need a specified 12V three-prong direct replacement; the Generic tungsten-lamp wig-wag relay lists that circuit format.

The F-1053 fits buyers assembling a compatible dual-output lamp circuit who value separate timing and a broad DC range. Its manual control mode and module format should suit the intended installation workflow.

#7

7. Generic 3-Prong Relay

• Voltage: 12 V DC

Best for: Basic 12V three-prong circuits.

Why it ranks #7: This automatic alternating relay is designed for 12V systems, but the listing gives no load rating or specific lamp compatibility.

A three-prong electronic relay provides the Generic wig-wag’s defining connection format for alternating lamp operation on 12V systems. Its universal-fitment description targets compatible automotive electrical applications, offering a straightforward option for buyers whose circuit matches that voltage and configuration.

The relay alternates lamps, and its three-prong design gives buyers a connection-format reference when replacing or adding a compatible flasher. The stated 12V DC coil voltage narrows the intended electrical system, while automatic operation describes the switching mode. The listing says it requires connection through a switch and appropriate wiring, so installation planning must account for those connections; it does not provide a lamp load rating or detailed wiring diagram.

Skip it if you need a stated lamp wattage or load limit; the Whelen SSFPOS listing specifies 160 watts.

This relay is for buyers with a compatible 12V automotive circuit seeking three-prong alternating operation. Its stated switch-and-wiring requirement and unspecified load rating are important boundaries when planning the installation.

#8

8. Generic Tungsten Relay

Best for: 12V tungsten-lamp replacements.

Why it ranks #8: Its 3-prong relay is intended for 12V vehicle lamp circuits and tungsten lamps drawing at least 10 watts each, limiting flexibility.

A direct-replacement, three-prong format and explicit tungsten-lamp requirement set this Generic wig-wag relay apart. It alternates power between two lamp outputs in 12V vehicle circuits, with each tungsten filament lamp specified to draw at least 10 watts.

The switched 12V input and two lamp outputs describe the relay’s connection role, helping buyers identify how it fits into a compatible vehicle lamp circuit. Its minimum 10-watt draw per tungsten lamp is a significant selection constraint: both lamps must meet that stated requirement. The direct-replacement description is useful for replacement planning, but the listing also advises checking original dimensions and specifications, since those determine whether the relay matches the existing circuit.

Skip it if you use LED lamps or need a broad load specification; the OONO F-1053 lists LED lamps and 10A per output.

This is for buyers replacing a compatible 12V three-prong relay in a tungsten-lamp circuit. The minimum lamp draw and original-part dimensions are essential fit checks; it is not the flexible choice for lower-draw lamps.

#9

9. Signal Dynamics Back Off

Best for: Brake-light alert signaling.

Why it ranks #9: This weather-resistant, 10A module modifies motorcycle brake-light signals; it does not serve as a headlight flasher.

Two selectable brake-light signal modes make the Signal Dynamics Back Off a brake-activated alert module rather than a conventional headlight wig-wag relay. Its patterns combine alternating flashes with a longer or steady illumination while the brakes are applied, serving buyers focused on rear safety signaling.

Mode one repeats a sequence of quick alternating flashes followed by a longer flash of both brake lights; mode two alternates left and right before flashing both and ending steady on. Those patterns give the rider or driver distinct brake-activated alerts. The 10A capacity and sealed, weather-resistant heat-sink case provide electrical and environmental specifications for installation planning. Its purpose is brake-light signaling, not headlight flashing, so the application distinction matters.

Skip it if you need a headlight wig-wag relay; the Whelen SSFPOS is identified for headlight and grille-light flashing.

This module fits buyers seeking a brake-triggered visual alert on both brake lights, including the listed motorcycle-riding use. Its two patterns and weather-resistant case are relevant, but it does not serve as a headlight flasher.

#10

10. Stop-Alert X2 Wagger

• Voltage: 24 V

Best for: 12–24V auxiliary LED setups.

Why it ranks #10: Although it lists 12–24V and 36 watts per channel, its legal disclaimer explicitly says it is not for headlights.

A 36-watt-per-channel circuit and 72-watt total load define the Stop-Alert X2’s output for alternating auxiliary lights. It accepts 12–24V systems and has a waterproof design, but its listing explicitly excludes headlight lamps, making the intended use an important part of choosing this controller.

The alternating wig-wag pattern is intended to draw attention to vehicle warning lights, while the two 36-watt channels provide a stated load limit for pairing auxiliary lamps. Its 12–24V range supports more than one system voltage, and automatic operation keeps the relay’s described role straightforward. The waterproof construction is relevant for vehicle installation. The product’s own disclaimer says it is not for headlights, so buyers shopping specifically for a headlight flasher should choose a different listed model.

Skip it if you need headlamp operation; the Stop-Alert WigWagger 72 is listed for auxiliary lights and does not carry this explicit headlight exclusion.

This suits buyers adding alternating warning or auxiliary lights to a 12–24V vehicle circuit. Its stated waterproof construction and channel rating are useful selection points, but the headlight exclusion rules it out for headlamp flashing.
