I haven't done anything to the car. It's a one owner that I started actually driving so some of the gremlins came out.

What I know...

I have no clue on electrics
The lights were working fine.
Both high and low beams don't work.
Driving lights and tail lights do.
One of the four wires coming out of the relay box blew (literally caught fire) and I replaced it on a trip to Goulburn and I have since replaced all four with new 15 amp copper wire but using the old terminals.
I have a feeling when they blew six months ago one headlight on low beam was temperamental before I replaced the one relay wire and when they both went I thought it might be switch related.
I haven't changed any thing from how it was wired.

Shoota I don't even know how to do that... What are the chances of them both going? Can I do a visual check???

You might be able to tell by looking through the front of the light to see if it's blown. Sometimes it's obvious, sometimes you can just see one of the filaments (fine little wires) is not contacting both ends where it should be to create the circuit. Sometimes with the lights on you can give them a hit and the filament will recontact and start working all of a sudden.
I've presumed bigger problems before due to two lights being out only to find out after wasting time it was just two globes gone!
It seems unusual that everything else works, just not two (of 4)headlights.
Start with the basics first- globes, power then earth.

Do you have a test light. Does power go into the headlight switch and come back out?? Check the hi/low beam switch. I've had a headlight switch work on the marker lights but not headlights (Ford Truck) and on my old Honda if you went from high beam back down to low beam to quickly the lights would go out, you'd have to go back to high beam then slowly pull the stalk and gently release it...........switch was starting to come apart................if you don't find a quick fix then start at the start of the circuit and follow the power along to you find where the problem is.

Unfam... Idont get the 'IM' references.

That's the auto spell check on my stupid phone supposed to be I'm or I am

And I have light. However not all are firing up.
Passenger low beam won't turn on in the low beam position but will when I turn on the high beams. Sealed globe works as I switched them around.

Any clues why this might be?? I assume it is the wiring somewhere. Or would it have something to do with the high/low switch (the indicator stalk)?

Need to get this thing blued...

Low beams should come on when the Headlight switch is pulled all the way out.

The dimmer switch (turn signal switch) controls high beam vs low beam. With switch pulled back towards driver, low beams should light. With switch pushed forward, low beams go out and high beams light.

Cheers dd, I know how they should work, and they did but alas they don't!

pushed forward I get nothing, middle one low beam light, pulled towards I get all four lit up... what the?

Yes, i added the description mostly for others reading this. My JDM 1200 works differently than described.

But all four elements lit up should not occur. Sound like a wiring problem or maybe a bad earth.
