Dipped headlights not working

[JonnyO]

My 2003 cab has no dipped headlights. Side lights and main beam work fine.
Any ideas where to start looking?

Have you checked the bulbs are not blown? that would be my first thought

its just that its both, at the same time and the main beam still works fine so I thought its likely to be something else.
