Test the voltage at the light fixture connection with a multi meter, follow the wire back until you find 12 volts again, check the ground on the battery, follow the ground to see if there are any damaged connections along the way, check the bulb seat for grase or corrosion, you can use break cleaner and air, dry fittings before connecting, sometimes wires get loose in the plastic connectors, you do not have to buy the complete connector, tell the dealership you want the inserts that go into the connector, usually you can get a wire with the end already on it and a little tool that pushes the old one out, insert the new one and connect the wire, sometimes it can be inside the wiring harness but you can always bypass a wire as long as you know where it ends up, just use the same size and type of wire and protect it with the right wire loom

Hi manolonusa,
It may have something to do with your headlights, but my first thought is they are just a symptom of another problem.
I'd check on the alternator. If the ALT fails, a good battery will keep the car running for quite a while. Sometimes the first symptoms are the dimming of the headlights. So:
Get back to me with the results. Once the alternator is ruled out we can check a possible headlight problem. But this way, at least you won't be stranded somewhere with a dead battery.

Easiest way would be to go back to where you bought it and make sure the bulb is installed that you bought....and show them. Ask if you can get a new bulb and change it in front of him. Call the dealership and talk to parts, ask if, indeed the hi and lo are interchangeable.

If the ground is good I would take a careful look at the light socket itself. There may be corrosion inside or on the power wire where it goes into the socket or it may just be making poor contact.
You can get a replacement one at any auto parts store. The last one I got was about $10. Get some heat shrink tube to cover your splices, it does a much better job of sealing the splice than tape. Hope this helps.

i think you hit the nail on the head with the ground problem,if you remove the bulb from the head light assembly,wiggle the black wire to see if the bulb gets brighter,if it does remove the bulb and clean and tighten the ground wire end.if it does not get brighter from a wiggle,connect the ground end of a test light to the positive post of the battery and probe the black wire,test light should light,if so replace the light socket.
