Passenger Side Rear Light Electrical Fault

[Sanandreas21]

My car has Lexus rear lights and on the passenger side when there is more than one bulb on they are dim.

say if the left indicator and brake light was on together it would be like the front of a police car, every time the indicator comes on the brake light goes dim and when the indicator is off it is brighter.

Any ideas what the fault might be as it doesn't happen on the drivers side.

Thanks

Try checking the earth on the faulty side, it may need cleaned or relocated to make a good contact.

Thanks will have a look in the morning when there is light.
