How To Synchronize Your Harley® LED Turn Signals
How to preform a Turn Signal Sync
Welcome to the world of motorcycle LED lighting!
Harley-Davidson® motorcycles equipped with incandescent turn signal light bulbs that have been replaced with LED turn signals will need to perform one of these turn signal sync processes below. Doing this sync process will allow your new HOGWORKZ® turn signals to function properly.
2014 and newer models with canbus / BCM electrical systems:
- Turn the Ignition on, but do not start the bike
- Turn on your 4 way hazards by pressing the hazard button on the controls
- Turn the Ignition off letting hazards run. If the bike has security they will flash 5 or 6 times and then pause. This is expected. They will go back to flashing normal hazard mode
- Let hazards run 1-2 minutes
- Turn the ignition back on
- Turn the ignition off and then back on
- Check the function of both turn signals
2001-2016 models equipped with a TSSM (Turn Signal Security Module) and are non-canbus / BCM
- Turn the ignition on, but do not start the bike.
- Turn on the RIGHT side turn signal and let it flash 2 times
- Turn on the LEFT side turn signal and let it flash 2 times
- Turn on the RIGHT side turn signal again and let flash a minimum of 10 times
- Turn on the LEFT side turn signal again and let flash a minimum of 10 times
- Turn the ignition key off and then back on.
- Check the function of the turn signals
- Thanks for riding with HOGWORKZ!

Does this procedure only work with specific manufacturers of lights? I have a 2006 FXSTBI Softail Night Train and I've tried this several times and cannot get the hyper flash to stop after installing all LED lights.

Have the same issue as Adam. Have a 2022 street glide special. All blinkers work normal, but turn signal on dash has a hyper flash like a build is out, it's a pattern blinking.

Having issues have done the rest many times still no front left signal working. For the price paid shouldn't have these issues, paid high dollar expect top notch products, not to have to email or call
