Anyone got any ideas, was in traffic today and lady behind comes to window and says you got no brake lights, thank you I says. We I were nearly home so got home and checked bulbs ok, checked fuse ok, checked connections ok, there is. Little conecter buy the brake pedal which when you push the brake pedal pushes a plunger type button and starts a connection I presume. Could it be this part and is there any way I can test it. It's on a Burstner elegance 821.
