Hi. I'm interested in buying aftermarket lights for my 2003 Chevy Avalanche and I was wondering if both the upper and lower half (sorry for the lack of technical names) of the lights are 100% compatible with these 2 trucks of the same year.
I'm pretty sure they have the same set-up. I know for a fact that 2003 was the first year for the new front end set up in the silverados and avalanche.
For that year I don't think they matched. I think it was the 2004 silverado that wen tot the cats eye head light that they would come close to matching.
