So, my LED replacement bulbs came in from superbrightleds.com over the weekend and I put them in last night. I used these bulbs for both the map lights and license plate lights:

The lights in the map lights work great and are super bright and clean... love 'em. But using the same bulb in the license plate light (which uses the same stock bulb as the map lights) results in a blown (Tail - 10A) fuse every time I turn on the marker lights. Going back to the stock bulb results in the fuse not blowing. I tried two different LED lights to eliminate a bad LED unit as the problem.
I suspect this has something to do with the resistance provided by the LED unit being different than the stock bulb, but I don't know why it would be a problem on the license plate lights and not in the map lights. I even bumped up the fuse to a 15A, then 20A just to see if I could get it to stay lit. Any ideas?
