Dim the lights while driving
g8trhntr posted a topic in 2014-2018 Silverado & Sierra Troubleshooting
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.
