i own a mazda 3. the problem is that with everything turned off my parkinkg lights still light up but with low brightness. also noticed that when i switch on the fog light (even when everything is off) the problem is solved.

OE or aftermarket fog lights? Who would know unless you did it how aftermarket was wired?

I'll never know what wiring was tapped into to power them and when but would go back and not just unplug them but remove them back to OE wiring and perhaps still something took a hit however long they did work that is the real culprit now,

i unplag the main power from the hids didnts just unplug the bulb. so you say that i have to focus at fog lights? and that when i turn on fog switch problem is solved, is not a random fact?

Plenty of IDKs where problem is. Parking lights can stay on dim and would be enabled normally with car off not even keys for most. Whatever you tapped into for power may go thru a relay that has gone bad.
Perhaps look for what powers plain headlights and request for running lights - may be in owner's manual? Then if no location listed try to find out anyway how that's done and one of us may be able to find out.
Any wiring you cut or tapped into is highly unlikely to be as good as original wiring so any and all of those in question.
Mazda 3 - now tell us what year so we have more of a chance too.......

HIDs and LEDs can be problematic as their power demands can confuse (FU) the modules -
Mazda uses a relay for parking lamps might look there - knowing exactly what year model etc and a wiring diagram would be a help.
PS- keep it STOCK - less problems AND repair is always easier

you are right abaut keeping stock i am not planning on doing anything else. its a mazda 3 2004 model. i donk think that there is a relay at parking lights. but can you tell me where you think it might be? i dont hear any clicking noise when turning them on like i hear when i turn on low beams.
