LED bulbs

It kinda depends on what you installed, and it depends on what voltage your car is at. Check your voltage with a good multimeter, should 12-ish volts (although it's likely too low, regulator issues are common).

If you just stuck LED's in there, yes, they'll smoke and you'll need to follow the advice posted previously.

If you bought drop-in bulb replacements and you pass the tests for proper voltage....you bought cheap, you got cheap.
