Whatever you do, stay away from the Sylvania brand LED bulbs. I've sold them to customers with multiple GM vehicles as well as tried them on my 2001 MC SS and they cause nothing but trouble. It seems they give off a strong RF interference which messes with the radios' reception. I installed a pair in my MC and the very next day the freakin battery was dead. Might be a coincidence but I also had no radio reception so I switched back to incandescent. It was too late as I think some damage was done to my BCM. Now I have an intermittent battery,brake and SRS light problem. They all come on at the same time and then go off after a few seconds. The frequency of this occurrence has increased over the last week and I think I might be headed for a new BCM. Sucks to think that these things are that sensitive. In any case, stay away from cheap led bulbs.
