According to another thread here on TBN, it's a restricted air filter light.

Yep. I actually added that to my Ford. It shares the bulb with my pre-heater.

My Repro dash had an unused socket. It's the red one next to the battery light. I just printed the symbol on a clear label and stuck it to the bulb lens. Just a little extra wiring while I was in there gave me the pre-heat light and the clogged filter light.
