What Is a Headlight Flasher Module?

A flasher module is a small controller that makes your vehicle's existing headlights and taillights flash in a warning pattern, using the factory bulbs rather than adding new bulbs or lights.

The most common pattern is wig-wag, where the left and right headlights alternate. Since the lights already fitted to the vehicle are used for the flashing patterns, it is a simple upgrade with a flasher module that warns other drivers in the area with no visible emergency equipment on your vehicle. That is why it is often the first upgrade a first responder makes to a personal vehicle.

  • Factory lights only: No extra housings, brackets, or drilling. The module uses existing bulbs on the vehicle.
  • Front and rear coverage: Headlights flash at the front while taillights and brake lights flash at the rear, all from one module.
  • Fully reversible: The module unplugs, and the vehicle returns to stock, which is especially important for a leased or shared vehicle.
  • Pairs with warning lights: Most builds run a flasher alongside grille and surface mount lights for full coverage.

Speed Turtle 2.0 vs. Speed Turtle 3.0

SpeedTech Lights carries two Speed Turtle Easy Flash Modules. The right model depends on your vehicle's make and model year, not necessarily feature preference.

  • Speed Turtle 2.0 (STE-EFM2): Built for GM vehicles from roughly 2007 to 2017, plus Dodge, Jeep, and Chrysler vehicles. Coverage includes Tahoe, Silverado, Suburban, Sierra, Yukon, Escalade, Charger, Challenger, Ram, Durango, Grand Cherokee, Wrangler, Gladiator, Chrysler 300, and Pacifica.
  • Speed Turtle 2.0 OBD Port (STE-EFM2-OBDP): The same module in an OBD port version for newer Dodge, Jeep, and Chrysler vehicles, generally 2018 and later.
  • Speed Turtle 3.0 (STE-EFM3-FORD and STE-EFM3-GM): The newer generation, available in different versions for both Ford and GM vehicles. Ford coverage includes F-150, F-250 and up, and Explorer. GM coverage includes later Silverado, Sierra, Tahoe, Suburban, Yukon, Colorado, Canyon, Blazer, Equinox, Traverse, Malibu, Terrain, Acadia, and Escalade.

Model year ranges differ by platform, so use the dropdown on the product page to confirm the exact fit before ordering.

What Vehicles Are Compatible With My Headlight Flashers and Taillight Flashers?

The Speed Turtle LED Flasher for Headlights and Taillights is compatible with a range of vehicles depending on the model of Plug and Play flasher you select. Some makes of vehicles include Ford, Dodge, Chevy, GMC, and more. Be sure to check the drop-down selection on the product pages to find out which LED flasher is right for your vehicle lighting needs.

How Plug-and-Play OBD Installation Works

Speed Turtle modules install through the vehicle's existing electrical connections rather than through spliced wiring.

  • OBD port models: The module connects to the OBD2 diagnostic port under the dash, which carries both the power and the data link needed to command the factory lights.
  • Harness models: Other applications plug into an existing factory connector, again with no cutting or splicing.
  • Activation: Patterns are triggered from a button or an existing vehicle control, so there is no need to drill a switch into the dash.
  • Removal: Because nothing is cut, the module unplugs and the vehicle returns to factory condition.

An OBD2 flasher module is the simplest way to add a headlight strobe kit to a late-model vehicle, and it leaves the factory wiring untouched. Pair this module with a switch box if you are also running separate warning lights.

Why Are The Speed Turtle Easy Flash Modules A Good Choice?

We offer two versions of headlight and taillight flashers from Speed Turtle. The type of vehicle you drive determines which flasher model you need. These are a great option for simple plug-n-play flasher functionality, making your headlights and taillights flash when you push a button in the cab. We highly recommend the Speed Turtle Easy Flash Modules for your vehicles.

Who Uses Headlight and Taillight Flashers

  • Volunteer firefighters and EMS: The most common use. A flasher adds warning presence to a personal vehicle that shows no visible equipment when it is switched off.
  • Police and unmarked units: Front and rear flashing from factory lights, often combined with hideaway strobe kits for fully covert coverage.
  • Security and private patrol: Where colored warning lights are not permitted, a white headlight flash still draws attention.
  • Tow and roadside assistance: Extra rear presence when stopped on a shoulder, using amber warning lights to notify other drivers in the area.
  • Construction and utility: Supervisor trucks that move between sites and need warning output without a permanent roof install.

Confirm your state statute before using any type of headlight or taillight flashers. Remember that flashing headlights are regulated in many states, and the authorization requirements for personal vehicles differ from those for marked units.

Frequently Asked Questions About Headlight and Taillight Flashers

What is a wig-wag headlight flasher?

Wig-wag is a flash pattern where the left and right headlights alternate instead of flashing together. It is the most recognizable factory-light warning pattern, and it reads clearly at a distance since the alternating motion is unusual in normal traffic. Speed Turtle modules produce wig-wag along with other selectable patterns.

Does a Speed Turtle module require cutting any wires?

No. Speed Turtle Easy Flash Modules are plug-and-play. Depending on the application, the module connects either to the OBD2 diagnostic port or to an existing factory connector, so nothing needs to be cut or spliced. The module can be unplugged at any time, and the vehicle returns to stock condition.

What is the difference between Speed Turtle 2.0 and 3.0?

The differences come down to the way the flashers fit on the vehicle (not features). The 2.0 covers GM vehicles from roughly 2007 to 2017 plus Dodge, Jeep, and Chrysler platforms, with a separate OBD port version for newer models. The 3.0 is the later generation and is available in two distinct versions for more recent models of both Ford and GM. Check the dropdown on the product page for your exact year and model.

Are flashing headlights legal on a personal vehicle?

It depends on the state and on who is driving. Many states restrict flashing headlights to authorized emergency vehicles, and volunteer responders usually need written authorization from their department plus a permit. Some states also regulate the colors that are allowed for flashers. Check your state vehicle code and department policy before installing.

Can the module flash brake lights as well as headlights?

Yes. The module not only drives the factory taillights and brake lights, but headlights can also be included in the system. So you get warning presence at both ends of the vehicle from a single unit. This is why flasher modules are common on unmarked and personal vehicles, where rear warning would otherwise require adding visible equipment.

Why are Speed Turtle products excluded from sitewide discounts?

Speed Turtle Engineering sets Minimum Advertised Pricing on its products, which prevents retailers from advertising below an agreed price. That means Speed Turtle modules are excluded from sitewide promotions and discount codes, while the rest of the catalog remains eligible for these discounts.
