I just bought my 21 trail boss LT which was manufactured in August 21. Drivers side DRL was purple since day one. The strange thing is that when the actual headlights were on the purple tint went away on the DRL. took it to the dealer (Serra Chevy nashville) and they gave me no issues about it at all. They admitted they saw it and that it wasn’t right and they replaced the whole assembly the very next day. It’s bright white like the passenger side now. Hope it stays that way. Now I just hope I don’t bend any lifters lol.
