18 gauge wire good for anything?

I've been stocking up on high quality wiring and connectors looms and such, I'm tired of having to cobble together or make parts store runs everytime I need to wire up something. So I'm buying in small bulk to build up a supply, I was shopping online and between comparing prices I didn't pay attention to the gauge, I bought 3 rolls of wire at 16 gauge instead of 14, it looks really small, is it any good for any project I might need on the car or is it just going in the bin and being stored for the next twenty years?#-o
