A guy from the area wants to trade his headlights with the housing blacked out and halos installed(the ones that are yellow rings when off) for my stock headlights. He was trying to get rid of his car but for some reason i find it sketchy that someone who put so much money into their headlights wants stock ones and take a huge loss. I may go check these out this weekend. Is there anything i should be looking for? I know about condensation but i need some other things to take a close look at. I dont want to get these and then have issues with them down the road.
