In a smoke-filled room, it's not only important that you can see – it's critical that you can be seen. In addition to the high-intensity halogen lamp, the rechargeable Fire Vulcan® is the first to have two powerful, ultra-bright LED taillights. Your partners can follow you through the thickest smoke; and they can find you fast in an emergency. The toggle switch makes it easy to go between strobe and steady modes, so you can use it to increase visibility at a fire or accident scene or signal for help.
