M Series Headlight Question

[derekuk101]

The bright lights no longer work on our M8540 no cab. The dim's work. When you turn on the bright痴, rear tail lights and dash lights come on but no headlights. Any ideas on what it could be??

Thanks in advanced.

I'm away from the tractor until this weekend, but I think it uses the same bulb for dim and bright. Not 100% though
