Roof lights not working.

[TheWaffen]

I put a rail with lights on the roof of my truck but they don't turn on, is there a different button to turn them on or are they only for show?

Press F4 then tick both the Aux light options

Thank for the help shadowfox

And once you have them "active" on the F4 screen, they illuminate when you use your bright lights (default K key).

You can also add a bull bar and throw lights on it. I got lights on my light box and bull bar. I'm surprised no one has named it a "bully" bar instead ...
It's excellent at shoving, pushing, nudging and ramming stubborn/bogus AI with. Every time you have been changing or putting on accessories on your truck it will reset the truck lights configuration. You have to press F4 and check the two auxiliary light marks again.

Happy in' and lightning up the roads.
