Yes, try this. Go into your TazerJL settings with engine off, then two start button presses until the start button light is on Run.
Enter the TazerJL's Lighting settings and find the Front Led Trn option, which should currently be on. Turn that setting off, then on again and while on that screen, put your left blinker on and let it fast blink until it finally blinks at a normal rate. Reboot and power cycle.
Now repeat all of that, except put the right blinker on until the fast blink stops and the right blinker flashes at a normal rate. Reboot and Power Cycle.
If one gets out of line later, just repeat this for that side.
I think I'm describing this correctly, but let me know if it isn't working and I'll check it on mine again.
Hopefully that will take care of it.
