I installed clear turn signals and Altezza taillights on my truck. The install was pretty quick and easy. The tail lights didn't look all that great at first cause they are bigger and brighter but only lit up half way. (The top lenses would light up with brakes and headlights, but the bottoms would only light up with the turn signals). So I spliced the marker lights to the turn signals so now, when you turn on the lights, all four light up. The turn signals function just fine. (If this seems confusing I'll show some pics once I get my camera back from my girlfriend). Once I clean the damn thing I'll post pics just so I can get some feedback from you guys on how it looks.
