i recently picked up some litronics for my boxster and as it would happen, a bulb was burnt out, one of the little parking light ones, no bigger than one joint of my pinky....
well, apparently even this small one is a hid bulb and so it ended up costing me $17 at a local napa....
i'm know it's because its a hid bulb and i would have guessed it would be more expensive because of that but it was quite a surprise nonetheless...
i'm just thankful it wasnt one of the headlight bulbs instead.
