You know the "horns" on the headlights? I bought red LED bulbs to go in there, they are freaking awesome. I know you're not supposed to have any kind of red light outside of your vehicle because of the fire truck thing, but when my headlights are on, you can't see the red lights unless you're really close, like beside me. Haven't been pulled over yet. And when I just have my parking lights on, those red lights come on too, it just looks badass.
