2020 2500 Duramax. Is anyone else having problems with their trailer lights? I’m having problems with the lights on all but one of my three trailers. Left turn signal and brake is not working. Took it to the dealer and they gave me some bs about how the truck can’t run led lights or more than 10 amps and blew me off. So essentially my brand new truck I bought for towing can’t tow a trailer with more than two tail lights. One of the two it isn’t working on is led and one is not and it runs the led lights just fine, just not the left turn or brake on both.
Hi all!! I just picked up a 2018 GMC Sierra 1500 and am still learning all the features of this truck. One thing I am finding difficult to figure out is how to dim the lights when you are driving. And I don't mean going from high beams to low beams. I mean turn off the main lights and just have the running lights on. This is a courtesy thing when driving through any checkpoint where there are guards. (Helps them keep their eye sight)
Seems that just turning the knob to the off position does not turn them off while driving. (Does work while parked.) Any suggestions? I have attached a pic of the light knob.
Looking to upgrade my halogen headlight housing (reflector) light output with some LED headlight bulbs.
I understand many people say not to do it as it blinds others, however I rarely drive at night and even then I live in a very rural area with little traffic. Most of the usage with be during the day with the DRL’s.
So does anyone have recommendations for what kind of LED bulb I should go with, one that works good in the reflector style headlight housing?
Looking for a simple bulb swap, I think you should be able to just swap the bulbs out right?
I have a 2015 GMC Sierra and I had a light bar in the back for the brake lights connected to the 4 plug trailer light connector, one morning I started my truck up and the light bar was on working fine five minutes later I go out to my truck and the light bar was off so initially I check the fuses and all seem goodthe blinker lights and brake lights work fine for the trailer but the running lights don't work so I unplug the bar and tested each connector with a tester and found the running lights don't work at the plug. is there anything I can check before I start following wires?
