All Badlands ATS-04 Speed-Sensing Self-Canceling Turn Signal Modules are designed to provide you with self-canceling turn signals on early/late model Harley models, custom builds or any American V-Twin motorcycle with an electronic speed sensor!

– Simple to install, this module adds a speed sensing, self-canceling turn signal feature to almost any vehicle.
– The perfect replacement for the obsolete OEM TSM/TSSM. (model specific)
– You will no longer need a Load Equalizer once you install this module.
– When either the left or right turn signal button is pressed, our module will continue to flash until a speed above 7-mph is detected, upon which time it will count down from a number of flashed before self-canceling, just like the OEM flasher module!
– Integrated 4-way flasher and will work with any style light, incandescent, halogen or LED.
– Many plug-n-play versions available as well as a hardwired version for universal applications.
– LIFETIME WARRANTY
– Made in the USA! 🇺🇲

What is the difference between the Badlands ATS-03 and new ATS-04 modules? Should I upgrade from the ATS-03 to the ATS-04?

ATS-03 Features

The ATS-03:

• Automatically cancels turn signals after approximately 22 seconds.
• Includes a built-in load equalizer, allowing LEDs, halogen, or small incandescent bulbs to be used without rapid flashing.
• Includes 4-way flasher/hazard mode.
• Does not require a speedometer or speed sensor to function.

ATS-04 Improvements

The ATS-04:

• Uses a speed-sensing self-cancel algorithm on most motorcycles equipped with an electronic speed sensor.
• Keeps the turn signal flashing while stopped (for example at a traffic light) and begins the cancel countdown once the motorcycle exceeds roughly 7 mph.
• If your speed comes down below 7 mph while the turn signals are still flashing, the module will keep flashing until the bike exceeds 7 mph and the countdown starts again.
• Provides more OEM-like cancellation behavior than a simple timer.
• If no speed sensor is connected (such as on older Harley-Davidsons with cable-driven speedometers), it automatically switches to a 30-second timer-based cancellation mode.
• Is available in several versions (ATS-04, ATS-04-A, -B, -C, -D, -E, and ATS-04-TSSM) to fit different Harley-Davidson wiring systems and model years.

Practical Difference

If you’re riding an older Harley or custom bike and just want automatic cancellation and LED compatibility, the ATS-03 does the job well.

If you want turn signals that behave more like modern OEM systems—staying on while stopped and canceling based on actual vehicle movement—the ATS-04 is the more advanced module and is generally considered the successor to the ATS-03. With both boasting the industry’s very first LIFETIME WARRANTY and the only module made in America upgrading makes perfect sense!

Badlands is the industry’s first and only American Made lighting module, since 1990!
