These Helmet Markers come in red only. They attach to a helmet with an adhesive velcro strip. The marker is easily removable to change the batteries which isn't often.  The batteries last an average of 150 hours and the L.E.D. should last 100,000 hours.

These would be great for EMS and Fire Fighters to place on their helmets for use at traffic accidents and in the case of the Fire Fighters, using these at night when fighting fires would enable other firefighters to see you in the dark and light smoke.

They were made for cyclists, but as you can see they can be adapted for the Public Safety Sector.
