74 Tailight Problems

Just something to check, on my 67 Dart 4 door I had one taillight bulb the kept burning out, I was following someone else drving it one night and I saw water sloshing around in the housing, I drilled a small drain hole and it didn't burn out after that. Apperantly the water hitting the hot bubl was burning it out.
You might also check the dome light wiring as the Dome light is on the same circuit as the brake or taillights(can't remember which it is), at least it was on my 75 Duster.
