Help! The tail light has stopped working on my 3en 400, the brake light works fine, but when i turn the headlights on, only half the binnicle lights come on and the head lights work on full beam and dip. But most frustratingly the tail lights do not come on,- brake lights work fine still. And i have changed the bulbs so its not one of the fillaments.

Please help as i need to get it on the road asap for the sumer.

I have a similar problem, the rear lights only light up when the front brake is applied. any ideas?
