Doc's Laser Fusion Modules are BRIGHT and should NOT be looked at directly because they are so INTENSE!!! They are small (3/4" square and 1/2" high) to fit them anywhere. These are epoxy coated to make them completely waterproof. These Laser Fusion Mods are great for places that are exposed to the weather and elements.
Installing them on the front rear wheels are best but they will fit almost anywhere. They are easy to install with an attached adhesive back pad and also included is 4 ft. of wire with a switch.
At $29.95 each, they are available in five colors,
