Snowmobile fuel gauges are hard to read in the dark. Glen adds a green LED to his Arctic Cat Firecat to illuminate the mechanical gauge at night. “The Arctic Cat Firecats have a simple mechanical fuel level gauge mounting in the top of the fuel tank. The problem is that when you are driving around at night, there is no illumination on the gauge so it can’t be seen. After nearly running out of fuel one night, I decided I needed to come up with something better than carrying a flashlight in my pocket to check the fuel level.” Thanks Glen! Link.
