Replacing headlight bulbs

Replacing headlight bulbs
Just got a pair of the sylvania 9003's Super brite bulbs. However, something weird is going on. One is bright as it should be..and the other is dull. I replaced the dull one and still the same problem. Then, I checked the fuse box and swapped the fuses... ala now the the dull one is bright and the other side is dull. Soooooooo... I changed the fuse... still the same problem. I am clueless about this. There is a larger fuse of sorts called "head" in the box...could that be the problem?

If the old ones work fine, then I woul say it is a problem with the new bolbs. If the old ones work ok still, then I would also say that it has nothing to do with the fuses. I'm sure somone will come along with the answer. Sorry I wish I could be of more help.

Silverstars are not the OE replacement. They are the bling replacement for the headlamps. If the bulbs you got have a blue tint to them, you have lost usuable light from what I recall.

Test your wires with a volt meter and see if you are losing current.

I had the exact problem.... Check the bulb itself and make sure it isn't cracked anywhere on the prongs. Mine was and I kept blowing fuses after awhile. High resistance = dimmer lights. What's funny is that I DID swap fuses and the same thing happened? I never could figure that out.

Mike,
Unless lightening strikes twice... I did replace the bulb in question. Yet, still the same thing. Maybe, I am not getting good conncection from the harness connector.
btw: thanks for the reply.. I dont feel so alone anymore.

i dont think you said if you put the old ones back in or not. i doubt it would be your harness if the old ones were working fine UNLESS you pulled em out by the wires.....come on...fess up!
at least try the old ones again!

Problem solved... I think. I replaced one of the headlight 10a fuses with a 15 and now both headlights are burning bright as they should. Could this cause a problem using a higher amp fuse?

I don't recommend putting a higher amp fuse. If the amps are higher than what the wires are rated for and you have a short to ground then either you have a fire or some burnt wires. I'm thinking now you may need to upgrade the wiring harness. I don't know anything about it, but I'm sure others can tell you about Roger Brown's wiring harness upgrade kit. In fact you might want to PM him about your problem. He would probably better tell you what is going on. Roger is a genius

ditto X3, but a higher amp fuse should not cause what he is talking about, its a safety feature, a 10A and a 15A should both let 10A flow w/o causing a voltage drop.
