Low beam headlight keep burning out

Hello, This may be an issue with defective sockets, too large of a fuse for the headlight, or bad grounds near the headlights. If these are HID bulbs, the ballasts may be failing as well. It would not surprise me to learn there is corrosion on the ground wires for the headlights, so check those first. Also, ensure the fuse is the correct size for the headlamps, and that the headlamp bulb sockets are not corroded or damaged in any way.
