We developed HYPE LIGHT VEST for Security Guards, and Search & Rescue Teams (and we have a camouflage version for Hunters) ... however, we also got approached by a customer in Michigan, IL, for his team that remove snow from paths and driveways by shovel.
HYPE LIGHT VEST is a floodlight beaming 1000 Lumens of mostly blue-white light - so it beams up to 150FT. It comes with RED and YELLOW filters in case you need 'night vision' or you don't want direct reflection of white light.
The vest is covered in highly reflective safety tape for worker visibility.
Available in 2 sizes - LARGE and EXTRA LARGE with extension Velcro Straps for the larger guys, and for when you are wearing extra clothing.
Available in High Visibility and Camouflage.
