If you desire to keep them, I have a pair that I could get to you if you wanted to change them to amber. The are glass with chrome guards. Came off a 48 6100.
I've been debating putting some on my one ton dually. I may change the cab out from the 6100 as its in a little better shape. It still has the holes from the lights.
Definitely need to be wired into the park lights. I know in the states, it was 3 cab lights, one center, one on each side, back then. Today its 3 in the center, one on each side.
