Based on the SB2 and SB3 firmware and designed for a car or a truck's third brake light where only 2 wires are present. Such as those commonly found on the rear windows of trucks and cars. The SBT requires only one signal wire and a ground return wire to implement; No need for a third constant 12V power. The internal circuit uses advance super-capacitor technologies to harness and store power each time the brakes are applied. The firmware allows the customer to select and store 1 of 4096 pre-defined profiles into memory in a tiny 35mm x 24mm x 8mm waterproof module.
