Check fuses/ relays.

Have access to a multimeter? Read if there's any voltage going to the connector.

Check The plugs, see if they stay in all the way. Maybe they wiggle out. All so, check ur alternator. take it out and test it at autozone. they do it for free.

Did you swap for a new bulb? Or did you swap passenger to driver and driver to passenger? That's the way you know for a fact, cause you're taking a bulb that you know works and putting it in the slot that supposedly doesn't work.

Also, did you ever get to try the multimeter? Check for corrosion too. That's a major problem with these cars, and being in the Bahamas won't help, as I know what sea air does to cars.

ok so i tried a full powered Optima battery and the passenger side high beam turns on but none of the other lights (passenger side low beam driver side lights, high & low) turn on hopefully tomorrow i'll have more of an update on the situation....... i heard from a friend that the turning signal switch has something to do with it but i'm not too sure how that may affect the headlights :gotme

I'm having a similar problem. Today I forgot my lights on of course when I came back To my car to head out to lunch my battery was dead. I got a jump (not the first time I've had a jump since I've owned the Z.) and one of my headlights would not come on. At first I thought that the HID bulb was killed by the jump. Then I noticed that my high beams were on in a diminished state.

When I tried to turn on my high beams the passenger side highbeam would not turn on. But when the low beams are set the driver's side low beam Is fully on and Both high beams are on diminished state.

I'm going to get a picture of it right now

when I got my car. Passenger high was very bright, driver high was very dim, and both low beams were faint, all at the same time, also my high dash light was on. I replaced turn signal switch, headlight switch, fuses were good, replaced all 4 bulbs. Still had the problem, only thing i did not replace was the relays, But I did swap realys, and everything stayed exactly the same.

Checked the wiring harness for any cut wires. coming throught the fender, all the way to under the hood. Everything was cherry.

I bypassed the relays and hard wired my headlights to a 3 way toggle, up for high, down for low, and off in the middle. I also ran my fogs to a toggle, just on and off.

Only thing that sucks is I have to turn on driving lights so I have tail lights.
And flip my toggle.

I know its not the best way of fixing the situation. But it works just fine.Been rolling for 3 months now with no problems, and I drive alot at night.

I ran a 3 way switch. Black is the middle prong and the blues are to the other ones, flip it one way for low and the other for brights, not the right way but it fixed my issue
