So, like it says..i replaced both map lights and the overhead dome with the 42mm 4410x9 festoon, went to turn them on to make sure they all worked, drivers side map, good, turned it off. Tried the passenger side, it blipped and i heard the fuse blow. Anyone have this problem before?

 

Something is touching ground.

 

Yeah I took the passenger side out, bent the retaining clips in slightly to make full contact, put the led back in blew the fuse again. Took it out replaced it with the regular bulb I took out and tried it voila, it works. Seems to be the bulb. I will contact the place I bought them from tomorrow and see if I can swap it out. No harm no foul.

 

Look at the wafer board and see if some extra solder is grounding two solder points

 

Raptor, i looked at it this morning again.It does look a little different than the other bulbs. I am going to send it back to superbrightleds.com and see if they will swap it out. Also ordered the two lights for the door lighting as well. These things are pretty frigin bright!
