This is much more visible at night.

Is it the combination switch or relay?
Daw_Two I think you need to check continuity in the combination switch first. You'll need a multi meter and pull off the lower panel but it's pretty easy.

Check out post #8 on this thread as to what pins to check. http://www.peachparts.com/shopforum/diesel-discussion/236946-dead-high-beams.html

Check them when the combination switch is in high and when it is not. If you get continuity when it is not in high beam position then it's the combination switch.
