2003 Envoy. Replaced lamp housings with TYC housings. New clear lens made a big difference even though we had kept the old ones polished. Looking at the housings they are virtually identical. As a note the wiring inside is larger than stock. They came with new headlight bulbs. We installed Wager 9011 HIR bulbs in the low beams, got them from RockAuto. The bulbs say made in Germany and came in a plain white box. They were less than $10 each so even it they aren't "real" HIR they are about the same price as a regular bulb. I can't say the bulbs are much more than the 9005's we had modded and put in the low beams.
For the cost new housings were worth it to us.
