Hi guys, I just got my Silverado 2500HD LTZ after trading in my 2014 Sierra 1500 SLT. I've noticed that when the lights are not on (I leave the knob in Auto) the interior blue lights around the radio and climate controls turn off. When I put the fog lights on or the amber running lights, it comes back on. When the blue interior lights go off and come back on, they slowly come in, like 'glow'. They dont just pop on and pop off, so that makes me think it's meant to do that? Is this normal?
Also, I read somewhere that if I wanted to install HID bulbs, I'd need to get an app on something and tell the truck they're HID's or something? Can anyone let me know if this is a thing?
Thank you all very much
