There was a post made in 2009 but I don't remember the OP username. They had the 1st gen led/altezza tail lights and explained how they had to modify them to make them work with the oem bulb fitment. I've spent about an hour and a half trying to find the post using various keywords in the search box with no luck. Please help me find this post, or if someone knows how I can make my bulbs work in the aftermarket tail lights! Thanks!
