C'mon guys, let's not be lazy. I know that GTS covers slide over the headlights. Just stop when it gets dark, walk to the front of your car and take them off. Like getting undressed for bed.
Now, for taillights, dump the crappy covers. Get Nightshades. It's a spray-on tint. You control how dark you want to go by applying how many shades you want. The best thing about it is the dual-benefit of being able to tint your 3rd brake light as well. Dual benefit beacuse it looks a heckuvalot better and it doesn't stand out to cops. Everyone notices you have covers when your 3rd brake light lights up nice and bright, while your regular taillights are darker. Not a problem with the spray-on stuff. boink
