yeah, I did that and figured out left from right. however, each set for left and right have different tabs in the back. (where the plug goes) One at 10:00 and 4:00-the other two at 2:00 and 8:00.

So which one is for the high beam and which one is for the low beam? They fit in each place on the core support and both headlight bulbs fit in each bucket.

It is very UN-like GM to make them different without some kind of reason. The only thing I can think of that makes difference in that area is the headlight plug itself.

I just don't want to put these in only to later discover why and have to take them out again. I hate rework.
