The GU blows stop lamp fuses from time to time.

When they go, 3 lights on the left hand side of the gauges light up, ABS, Traction Control & a 3rd I can't remember ATM. Also the cruise control turns on, but won't activate / kick in.

The lights on the dash come on when the brake pedal is depressed. Last night I got home with the 3 lights illuminated. Started up this morning and the lights were off but Cruise wouldn't kick in. Down the road a bit I used the brakes and at that point those 3 lights lit up.

Not sure where to look. I'm wondering if it could be the stop light switch (if it has one?).

I'll test the ABS tonight on the way home, make use of the rain and mud that's around at the moment.

Any suggestions????

Your stop light switch assy is actually two switches, 1 is dedicated for the brake lights and the other is dedicated for the Cruise Control.

IIRC both switch earth not power so any faults can cause weird issues at times.

The third light is probably the 'brake' warning light.

Have you swapped out any globes for LED or added any extra lights like repeaters... and... also check your trailer plug and loom for damage, corrosion etc
