Hello,
I have been thinking about putting cab lights on my w250 but I am not sure of how to run the wireing harness or how to make sure the lights are at the right spacing? I'm not a hundred percent sure if I want to go through with this but any advice on how it is done would be great ?
Thanks

 

It's relatively easy is you take your time. You should find someone that has them and STEAL theirs... .... Just kiddin'. Take the measurements from theirs and mark them on yours in the same spot with the white board dry eraser markers. It's a matter of drilling three holes for each light. Pre-make a wiring harness with plug in ends and fish it in the roof and down the inside "A" post. That's the hardest part.

 

This thread from Jim Lane might make it easier.
