Check these guys out.
I also keep a spare pair of T3 for swapping out at the meet. One works, one doesn't. But at least you have the correct bulbs in and won't get dinged for non-original headlamp bulbs. I don't think they make you do the drive by and check systems anymore like they used to (headlights work, horn, blinkers etc). But if you are driving it, those all have to work anyway. What I did was go through the drive through with my Halogens (used for everyday driving) which work, then swap out to the T3 the morning of the show. It takes about 10 minutes to do it. Rather easy.
For what its worth.
