These lights are going on a 2007 Aveo-or they were. On original lights all the bulbs are keyed to only go one way, same with the black ones-thats a no brainer. one of the bulb holders is low profile and the other is high profile. One the stockers the bulb placement is staggered to compensate for lo-hi profile. On the Altezza's they are the same height, so the high profile one hits the body where the pass-thru wiring grommet is. I pushed the grommet in to try and get it to fit-nothing. And now I have broken support leg as in the picture. I let the Ebay seller know that there might be a differance between years, I dont know but you guys might.
