Z3 headlight switch. Fixable?

[Pingu]

I don't see the mistake?

In my light switch the internal switch (circled below) is (was) intermittent.

So. I was thinking of cutting the wire in the boot (Red X in the diagram) and joining (Red Line) from the left side so both rear tail lights are supplied by the same wire. That's basically how the brake lights are wired anyway. The only reason the tail lights have different circuits is to allow parking lights. I don't use Parking Lights so supplying both 5W tail lights from the same supply won't be a problem.

But now I've sprayed tons of wotsit into the switch and left it a day to drain and put it back together and it appears to work. Time will tell.

Sorry, but I must have missed the bit where you said you were cutting the wire.

However, as you've noticed, you will have the problem that the indictors will turn on both rear lights when the ignition is off, rather than just the side indicated.

Also, if the problem is the circled part of the switch and you cut where indicated, only one of the front sidelights will work.

Yes. I know the left parking light would light up both sides. I mentioned parking lights.

I also just showed the rear. The front could easily be connected.the same way.
