After years of no real problems with our Mk II Galaxy, we've hit an electrical issue. When we turn the sidelights or headlights on, the brake lights also come on. This obviously needs to be sorted. Does anyone here have any experience of this problem? I don't think it's the switch at the brake pedal, as the brake lights work fine when the headlights are turned off. Although, have spotted that a sidelight comes on along with the brake lights when in use with headlights off. I changed a rear bulb about two months ago for the first time in the life of the car. We've had from new since late 2004. Any suggestions welcome. Andrew
