92 f150. I have replaced the right headlight bulb 3 times.
The low beam will not last longer than about 5 min. just quits working. I donot see anything wrong with the wireing. the plug the bulb pluged into looked ok. Anyone know why I can not get a bulb to last?
thanks

 

Did you touch the glass part of the bulb with your fingers? The oil from your hands will cause premature bulb failure?

 

maybe. I did have a hard time getting everything to line up. It I worn rubber gloves wout that help?
thanks

 

Wear a glove and/or wipe down bulb with alcohol. Also check your ground wires at the corner of the inner fender. Check the contacts in the bulb socket.

 

Test the voltage at the connector, that will show if you have a wiring problem or not.
