Sometimes I forget to switch over to wvo until about 10-20 miles into a trip and I want a reminder that I'm running on diesel when I could be running on wvo.

I also want a light that stays green when I'm on WVO. This way I will know if the Pollak valves are working and a fuse hasn't been blow.

If there's no power to the pollak valves, the default is to run diesel and I'd like to know if this happens. If no power is going to my cross over switch than neither light would be on and I'd know the fuse was blown.

It would be nice to have a auto switch over when the temp hits 160 but I don't mind manually switching over. I just hate it when I forget.

Has anyone done something similar to this?

What kinds of lights did you use and where/how did you mount them? I'm not great with electrical stuff but I can hack my way through it.

Thx
