Cadillac Escalade, EXT and ESV Forum - 2007-2014
So there is the HID, for low and hig beam, at the bottom, and there is the DRL at the top.
So what's up with the middle bulb in the middle? When does it turn on?
What is it used for? I have an 08 Base, and I cannot figure out if it broke or it is just for decor.
