Abstract The disclosed vehicle activated timed light circuit tester function is to test trailer light circuits from the tow vehicle through problematic connecters, confirming trailer wiring and trailer light circuits operate without the aid of an assistant when the trailer is connected to the tow vehicle. Confirming quickly all the trailer lights function and is safe to use on the road before use. Consisting of a vehicle mounted, vehicle activated timed light control circuit board, installed into the tow vehicle by one of three options: one aspect is built into a connector housing; one aspect is built into an accessory module; another aspect is a circuit board optioned by a vehicle manufacture; wired in series with the tow vehicle trailer light circuits; made to quickly function test all trailer light circuits in an automatic sequence by a single operator; control circuit board uses a common power bus circuit; power may feed from any active tow vehicle trailer light circuit providing power to the control circuit MCU; tow vehicle tail/park light circuit powers the trailer lights in test mode; tow vehicle tail/park light circuit activates test function by toggling tail/park light circuit on and off in sequence, leaving on; test function activation occurs with tail/park light pulses detected in a set time period, logic circuits operating the vehicle activated timed light circuit tester circuits; vehicle activated timed light circuit board activates outputs to trigger power individually to each trailer light circuit in a timed sequence; test function activation period is determined by design; control board automatically switches testing off when the designed test period is reached; vehicle activated timed light circuit tester control circuits are designed to fail light circuits in a closed state should the test function fail, fail safe condition allowing all lights to operate normally should a fault condition occur in the timed light circuit tester. 0 K' K n 0 rt ft W W ti ~. a I-T 0 6 6 r
