amber lens

I'm working on the light setup for my Jeep. Primarily used for overlanding with some light rock crawling. I've never put amber lights on my rig and am looking for feedback on their real effectiveness. How useful are they in fog/dust etc? Are they worth the investment?

Looking for some advice on lens color for lighting. I will be using a bumper that integrates a 30" Baja Designs light bar and has 2 Baja Design lower flush mounts on the sides. I was also planning to add some ditch lights on the A pillars. I don't have a lot of experience with amber lenses...
