I've been doing some research but i cant quite figure this out.
I have a 2015 Silverado LT and it has projectors but I believe the lights are regular, not HID. The dealer said they are HID's but I don't believe them. Are HID's just plug N Play when installing or do i have to do any drilling in the back of my headlight? This may be a dumb question, so i apologize in advance if I overlooked the answer somewhere.
