Basically the only thing that I haven't probaly done each time I installed was wear gloves, but I was careful not to touch the bulbs. The only other thing that I think besides expensive bubls suck is that I do have an amp in the back to my sub and I don't have a cap hooked up to it to keep the current stable. So the lights do dim a little when a deep note is hit when I have the system turned up. Other than that, if any one else has an other good suggestions, later.
My lights dim also like that because I don't have a cap hooked up to it to keep the current stable, but my lights haven't burned out in the 3 years I've had the car.
