SWAPPING TO LED LIGHTS FOR 2020 SILVERADO LT 2500HD DURAMAX

stephane lamoureux · March 16, 2021

I saw a few topics on swapping the Silverado 2020 LT 2500HD but they seem older posts from 2019. We just bought our 2020 and love it but I want to change the lights to LED everywhere. I went on Amazon to see but there are so many choices that I don't know where to start. Who else has done this ? help please :)

Thanks a lot. How did you handle the problem where LED does not consume as much power and could impact the truck? I naively asked my dealer thinking that since then they would have made something available but they were adamant that this could impact the truck and computer.

Has anyone been able to do the LED swap on their Silverado without the truck computer going wing nut. I am told it is a power issue since led takes less power then the old bulbs...

You need to order the Canbus along with your bulbs. The canbus increases the voltage signal to the trucks computer so you don't throw any codes. The bigger issue (IMO) is getting an LED to work in a non projector beam housing so you don't blind on coming traffic..we've all seen this.

that's great. thanks for the info. This should help me a lot in finding the right one then. I did spend time looking at LED for the non projector beam and found headlightrevolution.com do a comparison of LED and their beam issues and the GTR lighting ultra 2.0 (9905/HB3) came out on top though not sure if this has the canbus you mentioned. If I find one that works better then other, I will post it.

I went with these for the high and low beams.

And these for the backup lights.

So far no one has flashed me at night. Much better then the stock halogens. It was a pretty quick and easy install as well.

Did you have to use a canbus with the Fahren headlights? Or were they good to go as-is without tripping up the computer?

They were plug and play for me with no issues.

Thanks, just ordered the same as you for front low/high and the rear! How did you orient the front leds? I'm reading some people recommend installing them vertically, others at 9&3 o'clock. Don't want to blind other drivers and it sounds like you've accomplished that.

Sledguyry · April 13, 2021

I installed them vertically. They are working great. I believe the instructions call for them to be installed vertically. The connection on the stock bulb orientated vertically as well.

I ordered the one you got as well. Has anyone swap the high beam and fog lights over? Which bulbs did you use?
