Shown on the front of the bus for comparison, the Patent Pending Retro Fit BUSGATES®  Junior Arm is perfect for the rear stop sign on the back of the bus. It is made of the same high-quality fiberglass and is 4″ wide and 20″ long.  The fiberglass arm allows for the flexibility needed to stand up to the daily use of the stop arm deployment.  The 4 bright L.E.D. lights are on both sides to give maximum exposure to the oncoming vehicles from as far as a mile away.  L.E.D. lights are set to a continuous light stream to allow contrast with the alternating flashing lights of the stop arm panel. The 3″ 3M™ reflective tape meets Federal Regulations and allows the BUSGATES® Arm to be seen from every angle and the distance needed to warn oncoming motorists of a stopped school bus.  The BUSGATES® Rear 20″ Arm is installed with the included 2 sets of brackets along with bolts and nuts to mount, quick connects to power. Each BUSGATES® Arm can be installed and ready for use within 15 minutes. A flasher unit can be purchased for ease during installation or BusGates® can be directly wired to the flashing unit of the school bus.
