I looked at this and said to myself: "how in the world am I going to get to them??" I Googled replacing headlights on 2008 Cadillac SRX and I found a video by 1A Auto on a Cadillac CTS that made it easy!! It is still involved but, not all that hard. You have to remove the front tire, plastic fender liner and the front grill/bumper cover. The dealership will charge you a small fortune (I have been told $150-$200). Save yourself the money and do it yourself!!! Took me about 1 1/2 hours to do it. No parts, screws, or pins left over either!!
