i was painting my tail lights and i took 'em out and put them back in, didnt touch any wires or anything, and when i put them back in the far left bulb, and the two reverse bulbs werent working, i checked all 3 bulbs and they wre fused, what could've happened? that little metal thing in the bulb wasnt broken, that means the bulb is still good right? i didnt mess with any wires or anything so i'm confused, and i made sure everything was tight, so any ideas? also if i need new bulbs what kind are those?
