When the ambient level has reached a point (determined by the internal programming of the vehicle security module), 2 internal relays are energized to supply power to the exterior lamps. Circuit 196 (DB/OG) supplies power to the internal headlamp relay, which in turn supplies power to circuit 15 (RD/YE) when energized.
