The new combination LED light kit for stop arms provides added flexibility to easily wire the stop arm lights on a school bus with a 12-volt power source to provide either strobing/alternating flashes or steady state/alternating flashes from the LED lights included in the kit. Designed to replace 12-volt DC incandescent lights on air, vacuum and electrical octagon stop-arms. All of the flashing technology and circuitry is contained in the primary ultra-bright LED lamp, with the six-foot pigtail wire attached, eliminating the need to install a stop-arm strobe pack.
