I have a mercedes 2008 CLK sport. When I put the lights on, at the back on both sides, the lower quarter does not light up at all but the 2 top brake lights both light up. When the brake is applied they both get brighter and the centre brake light comes on.
The bulbs in the bottom are working fine so there seems to be a connection or electrical fault somewhere.
This only started a few months ago as before that the lights were all working fine
Can you advise how to get this fixed at a reasonable price as the car is only worth £6k so I am not spending £500.00 on it.
Many thanks
