passing lights is lighting when is high beams switch is on and parking lights is lighting on passing light switch... and left head light is allmost no lighting (only little orange light) rellays is working.. what happened? please help

First off, change the left bulb. (While you're in there, check the connector for corrosion.) Second, just because a relay clicks and seem to be working, it's contacting surfaces may have burned and have a layer of oxidization on the contact surfaces. Feed the pilot coil of the relay and measure the high-current part of it, using a multimeter. If in doubt, change the relay. //Magnus.

some time ago I´ve unconect one relay to seen what happens and the bulb shone weakly (like now left blub) i check rellays ( www.dustysjustys.com/IPL/JFIG835-1.jpg 3rd on left from top) and they works ... i can try rebuild relay system and make high beams flushing button

For as common as this is, I always forget the solution, but I think you first need to go through your headlight and parking light connections. Clean all the connections and make sure any and all grounds are connected well. I am going to be busy the next couple days, but I will see if I can find the solution. You might try using a regular internet search engine to search for switched ground headlights and see what you can find for Subarus.

switched-ground? it is like: + ---> light ---> relay ---> ground (-) ? switching and ralay system is normal or switched too?

Somebody here needs to have a head light wiring diagram for a first generation, I only have second gen diagrams, which use a DRL module.
Try replacing all the affected bulbs. Sometimes the bulb can fail and create a connection inside it self that backfeeds other circuits. (Unlikely but worth a try)

Battery - Fuse - Bulb - Switch (or relay) - Ground, as the relay's pilot coil is on an other circuit. So basically... For the bulb: Battery - Fuse - Bulb - Relay (opens or closes depending on circuilt below - Ground. For the pilot circuit: Battery - Fuse - Relay pilot coil - Switch (closes relay's ground) - Ground.

I had the exact problem... and the right bulb was dim on my Gen 1
I never did find the "real cause" But I did get them working. Pretty sure it was the connection in the steering column. In the process of undoing and cleaning contacts through the harness suddenly they worked again! Almost positive it was one of the connectors in the column.
Not to say that's were you problem lies... but go through connections. Check grounds!

ah..... everything goes wrong Justy have problems with lights and now with starter, motorbike have problems with lights too and bike is broken too ... I try fix lights with 2 new relays and connect them on original wires. And I check all lights connectors I found. It MUST work or I kill it !

I did a little searching and I think I can kind of narrow it down for you. I would check three things:
1) the fuse(s), often when a headlight is out on these systems it is because the fuse is blown for that headlight but it receives power backfeed through the system and lights dimly.
2) the combo switch and connectors in the column like Matt said, the combination of symptoms you describe would lead me to suspect the combo switch if all the fuses are ok.
3) grounds and connectors.
I know that's most of the lighting wiring system, but it sometimes helps to be systematic about it.
Here's some advice from another forum:
check the grounds!
with a dvm [voltage meter] set on 20v, connect one lead to center [headlight connector] terminal and one lead to outer terminal and note reading ~12 = good
then connect one lead to center terminal and one lead to good ground and note reading ~12 = good
then connect one lead to outer terminal and one lead to good ground and note reading ~0 = good
then stick one lead in engine coolant and one lead to good ground and note reading ~0 = good
I will try to get some wiring diagrams scanned in maybe tomorrow. I have house guests right now or I would do it sooner.

Wait i don´t find real headlight relays. Where are they hiden?

If your car is a 1st generation it does not use relays. Check fuse #3, and fuse #4. If all good check the connections at the bulbs, make sure the bulbs are okay. If that all seems good you probably need a new switch. If you have a multi-meter I can walk you through how to test the different wires to make sure everything is working properly. Terry

So I think the problem culd be only burned contacts in light switch..

Not necessarily, if you look at the diagram you see each head light has it's own power supply but they share trigger wires.
This means if the power is compromised to one head light it will take the left over power from the other head light and power itself in a backwards way.
ie. If you took power from one head light and turned on the low beam then the head light with no supply of it's own would find power from the high beam side of the good headlight and connect to the low beam trigger resulting in a really dim light from voltage drop accross the line.

Headlights are cheap, put 2 new ones in and if that doesn't work then try going deeper in to it.

Ok, I try it but i don't think it helps... Where is mounted grounds? I can't find them.

Did you replaced both head lights?
Do you have access to a digital multimeter that do measure DC volts and resistance?
