One of my running light's has gone out. I have discovered in order to replace it I will have to remove the front bumper. Since I don't want to do it too often I am also going to replace the other diving light.
My car is a 2009 CTS with around 40,000 miles.
My question is are there any other bulbs that I should replace since I'll be in an easier position to do so with the bumper off.
Mine also went out, but it was not the bulb, it was oxidized bulb connector inside the housing.
Don't worry about the bumper removal. It takes 15 minutes. You don't even need to take it off completely, just the top side and the fender well mounts to get access to the headlight bolts.
Another thing is that none of the other "bulbs" don't seem to be replaceable (parking and blinker LEDs), without splitting the housing in half, which again is not exactly easy.
I found the process to replace the DLR for a 2008 CTS sedan (with Xenon headlight) somewhere on this forum, and started doing it. As far as I could tell when I started to perform the bumper removal, it got pretty involved and required removing trim parts that seemed to be to be easily broken == and likely expensive to replace if broken. So I stopped, put it all back together, and went to my dealer. I'm pretty handy with these types of things, but this didn't seem like a low-risk process when I actually got into it.
I found a youtube video for the bumper removal process. It is actually very simple, and the bumper only needs to be pulled back a few inches to access the headlamp, which you have to remove to change the bulb. It took me about 30 minutes total. You remove the plastic trim on top of the radiator and about three bolts per side to get to the headlamp. Its a $400 bill to have it done at the dealer. Do a search in youtube and you'll get a pretty good idea for the process.
