I recently installed LED headlights on my 2019 JLU Sport from the basic halogens. I wired the drl and turn signal into my side fenders. To my surprise I wired it all correctly and it works.
However, when just battery is on the lights work perfectly.
But, when it’s turned on completely the turn signals don’t work. It blinks extremely fast on my dash and says my left blinker is out. Any idea of how to fix it?
I also have led fog lights and want to get taillights. How do I install them without the same problem.
Thanks!

the drl halo is causing the issue. You may need a resistor in line as the Jeep is reading as if the bulb is out. I would check to see if you have everything wired right and that you didn’t cross any wires.
the fog lights and tail lights will require wire harnesses that you buy with the lights. Install is simple. That is if you are not buying the factory units.

Your impedance is likely wrong now in the turn signal circuit. Have you ever noticed when you have a burned out tail light it still works but flashes fast for the indicator and that is often a bypass circuit with different impedance to cause that so you see it and replace the primary turn signal. When you added the turn signals the match is out - for what you bought can you find a YouTube Tutorial. I have upgraded LEDs and Halo Oculus headlights but did not do the turn signals and they work fine with the halos wired into fuse 52 on the fuse box

What headlights and turn signals did you install? Specific links? This can help us determine the fix

Turn signals are stock Sport Halogens. I’m embarrassed about the headlights I bought. But hey they work. Was curious about their longevity. https://www.ledfactorymart.com/products/newest-9-led-halo-drl-headlights-for-2018-jeep-wrangler-jl-and-jeep-gladiator-jt?currency=USD&utm_medium=cpc&utm_source=google&utm_campaign=Google Shopping
Try disconnecting the wire that connects the halo to the fender turn signal and see if that
fixes the signal out issue. You may need some sort of resister between the oem turn signal and halo.
here is a thread I found. https://www.jlwranglerforums.com/forum/threads/led-turns-signals-reprogram-or-use-resistors.77701/ I’ll keep looking though

Edit: check out this 12 page thread. May have your fix. https://www.jlwranglerforums.com/fo...fender-led-drl-switchbacks-on-jl-sport.25959/

Thanks so much! I’ve seen maybe some resistors that would work. That connect to the wire to the ground? Not sure. Have to do more research.
