Okay so i have a 318i 1999 e46 - I don't like the lights that are on the back, They are frosted white lights and i wand the original red ones back. Now do i need to buy whole new lights or just the light covers ? Second question :) ... I would like to get some of the halo circle front lights, Similar question; do i need to buy the lights in whole or can i just fit the halo led's into the light that's already there ? As you may notice i love cars but am a bit clueless :?
