The Firecharger is a pull system and comes with a traditional red T-handle with white lettering. But we added more after a quick trip to Office Depot for some red press-on labels. Now, the T-handle's location is really obvious to safety crews. This is particularly important in the event of a wreck where the driver is unconscious. With the help of my father, Robert, I mounted the system in the car so I already know where everything is and what lever to pull in the event of a fire. But if I was knocked out it would be up to the safety crews to figure out where the on-board extinguisher was located-now that it's clearly marked, they can.
