The red & white retroreflective tape you see on truck trailers is grade DOT C2. It gives the brightest reflection over the widest viewing angle. The engineering grade material on fire trucks is less bright, but stands out due to the large surface area of the side of the truck. The DOT C2 tape is available in lots of auto supply stores and the auto supply of many other stores.
SOLAS tape (Safety of Life at Sea) is brighter but over a narrow viewing angle. It is designed to reflect brightly back to a single point such as a searcher behind a spot light on a helicopter or search boat.
