Off side brake light dim and when lights are on brake light and tail light are off when braking.
did notice last night that with lights off and brake lights on , number plate lights were dim?.
Changed both bulbs .
Only getting 11.6v to brake light wire before plug on light unit , checked on various earthig points.
​​To me iitseems like a damp plug somewhere or water damage somewhere.
just don't know where to look.
If anyone can help
Many thanks
Gary.
