LED woahs

ksenter · June 27, 2017

Hello,

I drive a 2014 silverado z71 LT and recently installed Lumen G8 LED low-beam and foglight replacements. The fogs work wonderfully, you can actually see them from the cab now.

The low beams are excellent and SUPER bright...once they power up properly. Issue is they will come on for about 4 seconds, then shut down. Over the next 2 minutes time they will quickly flicker once or twice and continue to not work. Approx 2 minutes later they will power on and work well until you shut down the truck and run through the same sequence again.

I have read this may be due to PWM or Pulse Width Modulation that power the low-beams, particularly for the DRL. However this also happens at night when the sensor would actuate standard headlights, not DRL. Swapping from Auto lights to Power-On makes no difference.

Would this be resolved with a plug-n-play anti-flicker harness or will this need a resistor/capacitor orrrr......

I'm pretty good hands-on turning wrenches and installing things, but wiring/electrical has always been a nemesis of mine.

Your assistance is greatly appreciated in this topic.

I sorry to hear of your woes. Have you reached out to the manufacturer?

never touched base with the manufacturer. I did reach out to the vendor, CarID, which was absolutely no help at all. They offered to take the led bulbs back but offered no assistance otherwise. Long ago, I ordered an "anti-flicker" harness and that resolved the issue completely. plug and play, perfect.

I've had these on the truck for months now and absolutely love them as I drive in very dark, unlit, places often...way out in the middle of nowhere. Impressive lighting!

posted for information so that it may help others in the future.
