I put some hyper superplazma bulbs (the really bright ones) in my car about 4 months ago with hd wiring harness. And sometime in the last couple of days, one of them burned out. Or stopped working. All the filaments look like they are intact. But it doesnt light. Has anyone else had any kind of similiar experience with these?

 

I've had bad experiences with Hiper...the first set I got burned out in like a month, so I got another set, the regular wattage, those burned out in a month and a half? but I got another set, the super plazma overwatts that were suppose to be purple and they weren't and those burned out high beam and low beam. So whats wrong with Hiper I'm just tryin to find a more dependable set of lights now...

 

Swap bulbs... that'll tell you if the problem is with the bulb or power to the wiring...

 

I already did; it is the bulb. I ordered a different brand. See if they are any better. Krypton.
