What year truck are these installed on? I have a set waiting for install for my 2018 1500 LTZ but I cant get the original reverse bulb out. Taking the taillight off the truck body for access is no problem, but the reverse bulb seems like its frozen in place (i dont want to break anything). Might have the dealer install on my next oil change. Have watched youtube videos and it seems like a simple twist to access the bulb, she doesnt want to budge in either direction left or right.
