There's no over-voltage anywhere near there. Everything runs on the battery at 14 volts (ish) max. If the bulbs are running hotter than they should, they are higher power than they should be. If that's not the problem, it's just crap plastic. Oh, if you happen to be a "two-footed" auto driver whose brake lights are on all the time, that wouldn't help, but I can't believe it's the whole problem.
Engineers do it with a torque wrench
