Anybody have any ideas what could make this keep happening? I've replaced it 3 times now. Goes out about every 3-4 days.

Thanks for any input fellas!

There's a ground for each headlight right behind the housing. (Black wire.) Pull the housing out and check for a dirty / corroded ground first.

 

I don't think a bad ground would blow a fuse... would it?

For the fuse to burn out it means there is too much current flowing.

have you tried replacing the bulb?
If its not the bulb, then it sounds like there is a short in the wiring somewhere

or you have a bad set of fuses??? Are you sure its the right size fuse? Maybe get a new set before you tear up the truck looking for a short in the wiring.

 

Just today I hauled a package of "high temperature" headlight bulb sockets to a mechanic so he could replace one behind a headlight where the terminals were crimped on the wire inside the plastic plug body and appearantly the crimp was loose enough to cause resistance and resistance increases heat and melts stuff like insulation and plug body's and if it goes on enough, one day a hot wire shorts on a ground and fuses blow.

Just sayin ....

 

You nailed it, Sir! I finally had enough of replacing fuses and bulbs. Took it to a mech and had him look at it. He showed me where way down in the socket on the pass side it was melted between two of the contacts. I ordered a new one and it'll be here Thursday. Hopefully that all it is but it sure seems that way.
Thanks!

 

That'll do it, one of those leads is always gonna be a ground path, the other 1 or 2 (depends on if single or dual filament) is/are hot when switch is in on position.

Glad I helped someone ..... haha ..... Take Care .....

 

Poor contatct (on the positive or negative side) = increased resistance. Increased resistance = increased heat, lower output.

 

I finally got the headlight socket in today. Installed it and so far so good. Thanks fellas
