How do I know if I have 9012 or d2s, I guess halogen or hid? It lists both in the manual and arent the easiest to get to and pull out. I had enough trouble with the 45 led cornering light. It broke off in the light housing then fell apart. Took about 1.5 hours to fish it out,put it back together and all is well again. Problem is they sell these bulbs but are they actually made for the car? The bulb itself fit in the wire socket but putting it in the hole to mount it was excessively tight.

 

If you have the drivers preferred package with the power folding mirrors, heated steering wheel, 6 way power passenger seat. Also by the color of the light output, whether its regular white like a normal bulb or that blue-ish hue'd xenon light.
