Lighting problem-Bad Earth?

[DAVEY DEE]

Hi peeps.

Got an issue with my lights:
1) When I brake the brake lights work but the side lights come on.
2) If I turn the side lights on then the brake lights are permanently on.

The bulbs haven't been changed lately & the rear cluster connectors look fine.

Does anyone know where the earth for this system actually grounds on the chassis? I thought I'd try & clean that as the 1st step to narrow things down.

Cheers.

As far as I'm aware it doesn't affect fhe indicators.

Connections, bulbs etc all look fine.

Does anyone know where this part of the electrics earths to the chassis please?

All sorted.The lovely fitter at work fixed it for me.All the bulbs were working but a brake light bulb was short circuiting between the two filaments.....I would never have found that but he knows how to work those electrickery boxes with prongs !
