HeadLights?  

I have had the same problem in my mustang. We replaced the fuse several times and the same thing kept happening. We bought a little bit higher voltage fuse and put it in there and it works fine now. It could be something in the electrical system causing it not to work right when you put in the right fuse for it also.

Sounds like something is not right...Maybe it's just the fuse again..Many times the inside lights work when the head lights don't...I hope you get it fixed or you will be a fairweather driver for a while..

If it's not the fuse maybe you need new headlamps? Or they could have come loose at the connection...Lori

Good luck Marcie, I hope its just the fuses. Sometimes you can get some good advice at AutoZone, you should have some of them where you live. They will sometimes even come out and test things for you. Stop in there, smile pretty and say please. Most of the time they are really helpful to women. I have had them test my battery, alternator, voltage regulater. They have even changed my windshield wipers for me. Check with them before going to the shop.

Since you've been going through so many bulbs, and even changed the fuse, it sounds like maybe there might be a short somewhere. The dash lights and parking lights I believe are on a different circuit/different fuse. There might be a wire loose or something from natural corrosion. Electrical problems are hard to trace in a vehicle, especially the new ones where everything seems to be controlled by computer. Since you've already tried the obvious solutions with new bulbs, and fuse, and it still keeps happening, it might be easier for a shop to find out why it continually blows bulbs. Good luck!

It could be a short in the wire. What you should do is to take it to the mechanic and have him look at it. He will examine the engine, and also was it raining or snowing where you are? Sometimes it might get wet inside. It is definitely something wrong inside, not with the bulbs, and it could be a fuse, but it probably more serious.

I think you have done all the right things regarding this problem.
I was wondering when you change the bulbs, do you handle them
with your BARE HANDS?
I used to work at an auto parts place & I know that when the guys change the bulbs they never touch the bulb with their hands because the natural oil residue causes it to burn out faster & I usually saw them changing out the fuse at the same time to cover the bases.
It does sound like an electrical prob also like everyone else said, I know it must be fustrating.
Cars are like babies, always needing their diapers changed..LOL
Best wishes on finding the problem with you car.
=D keep smiling!
