LED Bulbs For Chevy

Just picked up a 2019 Chevy LTZ 2500HD, I am coming from a 2014 GMC Sierra 2500HD. I ended up removing the new LED bulbs I had in the Sierra and was hoping I could just pop them into the Chevy. I tried to search it on the forum and found some info on the LED but it seems as most are going with HID. It looks like these trucks have a cap that goes over the bulb housing, so I would assume there is going to be no way of fitting the LED which has the fan on it it this housing with installing the cap back on. I would be worried about leaving the cap off as I would imagine dirt would get in the housing. I have read about also adding a canbus for the LED lights as they could cause codes on the truck?

Thanks

Higher end leds are integrated canbus and won’t flicker. As for the dust cap, on my wife's terrain, I ordered two new ones from gmpartsdirect and hole sawed a 3” hole then took pvc endcaps and used marine caulk adhesive to seal it up. It will allow for the fans and fit factory.

If you are talking the headlight LED bulbs, I have Super Nova v.4's installed in my highs and lows. Didn't have to do any modifications. For turn signals and tail lights, you will need to add resistors to keep the hyperflashing at bay.

I'm about to get rid of my LED lows for HIDs. After installing some in my MK4 Jetta, I'm beyond pleased with the performance, compared to LEDs.

Nevertheless, I have replaced all the exterior bulbs with LEDs.

Sounds good, did you drill any small holes in the PVC cap to allow for ventilation for the fan or is it alright completely sealed?

Unfortunately no. I’d like to but I figure water and dust would find its way in. It’s completely sealed. I tell her to turn them off unless at night (drl’s) bit she doesn’t. We’ll see how long they last.
