fusees
Red warning flares
Fusees is the plural of fusee, a word with several specialized meanings united by the idea of a device that burns.
A fusee is a colored flare used as a warning signal on railroads or roads: The crew set out fusees to warn approaching trains.
In clockmaking, a fusee is a cone-shaped pulley that equalizes the force of an unwinding spring.
An older meaning is a friction match or the flintlock mechanism of a firearm.
