I don't know if anyone can help my rather old mercedes is a real great car and servicing keeps it working fine however recently a couple of electrical faults have happened which i thought about fixing myself. When i turn on the headlights the dash lights go out, i noticed the digital clock light lost its light about 3 months ago but this wasnt a big concern i have also noticed one brake light constantly goes out even after changing the bulb mainly when i put my foot on the brake when i release the foot brake every morning! i don't know if it is just a short or some new fuses needed! i'm not that great at fixing car problems but any help would be greatly appreciated to keep this work horse going! many thanks Mark
