About 3 months ago what I thought was a burned out left front low-beam bulb turned out to be a bad socket. The half of the socket was melted and crumbly. Bulb was good; have had no blown fuses. I spliced a new socket in place (solder and shrink wrap). Yesterday the beam went out again. When I checked it out I found that the insulation on the two wires had melted next to the socket and there was a short. Pulled the two wires apart and the bulb came on. When I removed the bulb I found that the inside of the socket was starting to melt again. Just finished replacing the socket for the second time, and the bulb (H1155) too.
Have not had any problems with the bulb on the passenger's side of the car.
Any ideas why this is happening? For what it is worth, I placed a multimeter between the neg battery and the contacts in the socket, got 0.26 volts on one side, 0 on the other. There is a plastic cover on the back of the headlight assembly; I left it off for now, thinking it may be contributing to excess heat buildup.
