I have replaced the bulbs in both my low and high beams with Street Glow Xenon, and have had numerous problems with the lows, i have replaced them 5 times now, but the highs seem to have no problems. The grill is easily taken off, and the retaining clips on the top of the lights are easily pryed up for access to those black rubber covers. I have found this to be the easiest, as i have had them out numerous times. Do you all have the problems with your tail lights, they have burned out many times on me also. I replaced them with LED aftermarket bulbs, but soon realized they looked very out of place. Is there a way to get the "tinted" tail light lenses found on the SS Trailblazer?
