changing Daytime Running Lamps

I just changed the left DRL on my 2000 z71, but it was a pain. Getting to the 3157 bulb-housing was easy, but removing the bulb was really difficult. Is there a tool for this? seems like there should be since there are 4 flanges holding it in, 2 on each side of the base of the bulb. What's the best way to hold open the flanges to remove the bulb (besides breaking the glass and using 4 screwdrivers!)?? anybody been there before?

Thanks

The first time I did it, I was confused. But all you have to do is have a firm grasp on the base of the bulb and pull. You have to put some strength into it, but thats it.

Don't you just turn them ninety degrees and then pull the assembly out of the socket?

Ive changed mine before, not sure how I did it now. I think tidalcock is right.

The 1157 and 1057 bulbs turn 90deg then pull out - they have round bases. The 3157 is a rectangular base and TexasF355F1 is correct - grab firmly and pull straight out.

Just pull the relay for them under the hood so they go out. THen you don't have to worry whether or not they're blown.
