Headlight Switch - Be warned.

[Pingu]

These light switches are quite complicated, and I'm surprised that there are not more problems with them.

There are three seperate circuits inside (one with a dimmer potentiometer).

It has been "fun" reverse-engineering one .

Sorry to hear you are still having problems Nigel. It's possible that the connector has an internal fault that is shorting or overloading the switch. It might be worth splicing on a connector or get an auto electrician to change it.

Just a heads up for anyone buying a brand new one, check with BMW first they were cheaper than online by nearly £20. Just ordered one from Cotswold BMW £91

Do you have a part no for the light switch.

Hi all
The saga of the light switch continues.
Firstly I bought a good secondhand switch to replace the faulty one,that lasted a couple of days so I purchased a new one again that lasted a couple of days.
The fault I have is my dash lights do not work after a couple of days.
I have checked the electrical connector and this has some minor damage from the original fault.
Any ideas why this keeps doing this and anyhelp would be appreciated.
Regards Nigel

I would suggest the problem is not the switch. Check all wiring in and out, short somewhere etc etc?
