More particularly, this 5 invention relates to an electrical connector assembly for a drawn or drawing vehicle and to a discernible current detection device for such an electrical connector assembly. Background to the Invention There are many types of vehicles on the market today to supply electrical connections from a hauling vehicle to a towed vehicle or trailer or visa versa. The purpose of the connector is LO to provide an electrical connection between the vehicle and trailer for each electrical circuit, weather it is a lighting or auxiliary circuit. However, research has found that in all the hauling vehicle's to tow a trailer prior to the year 2000 AD, have filament globes in the vehicles rear lamps. The filament globes in the trailer lamps electrical circuit that indicates right and left turn, clearance, tail, and stop lamps, the connection by way of a cable one end L5 connected to the vehicles rear lamps, turn indicators stop and tail lamps and the other end of the same cable connected to the electrical connector vehicles socket that mates with the trailer electrical connector plug to supply electrical engery to the trailer lamps. Some vehicle's that are manufactured after 2009 AD have LEDs, light emitting diodes in the rear lamps, the wiring is thinner, the Light Emitting Diodes LEDs current draw is less than ?0 the current draw of filament globes. These vehicle's that have Light Emitting Diodes LEDs have a constant pulse sense current flow in the trailer module power supply to the vehicle's trailer socket, and is designed to sense a load of the trailer's filament globes when the trailer's electrical plug is connected. My research has found, vehicle's installed with a pulse sense current flow module to the 25 trailer socket. When towing a trailer with Lighting Emitting Diodes LEDs lights, the trailer LED lights flicker or pulse or visa versa due to a small circuit current draw lower than that of filament globes. 30 3 Summary of the Invention According to the first aspect of the Invention, there is provided an electrical trailer trigger circuit on a Printed Circuit Board (PCB) including a switch: 5 a housing defining an inlet for a cable have a number of apertures: a printed circuit board (PCB) located within the housing at a predetermined position related to the apertures: a plurality of electrical connecting members fast with the housing for connection to electrical circuits of a vehicle and in communication with the PCB: LO Wherein the PCB board is submerged with a heat resistance liquid within the housing at a predetermined location and wherein tracks of the PCB are laid out so that the leads are provided between the electrical connecting members and the PCB and a switch.

(Figure 1) shows a housing, 2, defining inlets for cables having a number of apertures, 5 4,6,8,10,12. (Figure 2) shows a printed circuit board, (PCB) 14, located within the housing, 2, and wire cables 20, 22, 28, 24, 26, protruding through the apertures of the housing. (Figure 3) shows a heat resistance liquid, 16, of which the printed Circuit Board (PCB) is submerged within the housing, 2, and wire cables, 20, 22, 28, 24, 26, protruding through the L0 apertures of the housing. (Figure 4) shows circuit layout of the printed circuit board (PCB) 14, earth strip, 18, wire cables, 20, 22, 24, 26, 28, a switch, 30, connecting wire cables, 48, 50, four blocking diodes diodes,40, 42, 44, 46, four resistors, 32, 34, 36, 38. (Figure 5) shows a hauling vehicle, 78, trailer wiring electrical connections prior to the year L5 2000 AD, from the hauling vehicle's rear lamps 82, 84, through a vehicle socket 56, and earth return wire, 76, a trailer, 80, a trailer plug connector, 58, with electrical wire connections, 68, 70, 72, 74, 102, that are connected to the trailer's rear lamps which have filament electric bulbs, 60, 62, 52, 54, 64, 66. (Figure 6) shows hauling vehicle, 122, manufacture after 2009 AD and trailer electrical ?0 connections, 118, 120, 112, and a trailer trigger circuit, 116, including a switch, 114, through a vehicle socket connector, 110, a trailer, 124, a trailer plug connector, 108, with electrical wire connections, 98, 100, 104, 106, 102, that are connected to the trailers rear lamps which have Light Emitting Diodes LEDs, 86, 88, 90, 92, 94, 96. The Invention is a Trailer Trigger to stop trailer LED lamps from having a pulsating flicker and 25 can be switched off when not in use. Our Invention The Trailer Trigger is installed in the vehicle and the circuitry, (Fig 4) is designed to prevent pulse flicker in vehicles manufactured after 2009. These vehicles (Fig 6) 122, with pulse sense BUS electrical systems, 118, sends out signals from its computer to the vehicles trailer connector, 110. When a trailer, (Fig 5) 80, is electrical connected to a 30 vehicle (Fig 6) 122, the vehicles BUS computer system, 118, the vehicles computer system senses a current load, through (Fig 5) the trailers, 80, rear lamp globe filaments, the left turn signal, 60, the right turn signal, 66, tail lamps, 62, 64, and the stop lamps, 52, 54. The (Fig 6) BUS, 118, computer system current load is designed to sense a small current load which will not affect globe filaments to pulse and flicker, as globe filaments has a higher 35 current load on the BUS computer system. 5 (Fig 6) Vehicle, 122, when connected to a trailer, 124, through vehicle socket, 110, and through a trailer plug, 108, to the electrical wiring connections, left signal, 98, right signal, 88, tail, 106, stop, 104, which are connected to the trailer lights, being Light Emitting Diodes LEDs, left turn signal, 86, right turn signal, 88, tail lights, 90, 92, stop lights, 94, 96. The BUS 5 computer system, 118, does not sense a current load, as the LEDs are designed to function on low voltage and low current draw. When the trailer LEDs lights are connected to the vehicle, the trailer LED lights will constantly flicker, to overcome this problem, the Invention, (Fig 6) The Trailer Trigger circuit, 116, is connected to the trailer wiring BUS computer system, 118. The Trailer Trigger wiring LO circuit (Fig 4) left signal, 20, right signal, 26, tail, 24, stop, 22, earth return, 26, when The Trailer Trigger (Fig 6) 116, is connected to the BUS computer system, 118, vehicle trailer wiring, the Trailer Trigger PCB board circuit (Fig 4) 14, loads the vehicle BUS computer system, trailer wiring circuits through blocking diodes, 40, 42, 44, 46, and load resistors, 32, 34, 36, 38, to earth bar, 18, to earth return wire connection, 28. (Fig 3) The PCB board is L5 submerged in a epoxy casing, 16, in the housing, 2, to transfer heat away from the diodes and resistors to the outer housing, 2. (Fig 4) Earth return wire connection, 28, is connected to a switch contact, 30, to switch, 48, to earth connection, 50, when the switch, 30, is closed, the BUS computer system, (Fig 6) 118, senses a higher current load and the LED lights on the trailer will stop pulsating and flickering. The PCB board (Fig 4) 14 blocking ?0 diodes, 40, 42, 44, 46, prevent reverse current, (Fig 6) to the trailer, 124, LED lighting circuits, 86, 88, 90, 92, 94,96. As shown on (Fig 6) the Trailer Trigger, 116, connected to switch, 114, and switch connected to earth negative return, 112. The Trailer Trigger can be installed on either trailer or the hauling vehicles trailer wiring system. Modern day vehicles that tow trailers with Light Emitting Diodes for trailer lighting, the LEDs )5 can pulsate and have current flicker which is hazardous to traffic and the vehicles battery and computer system. The Invention The Trailer Trigger with a switch and blocking diodes will prevent the trailer lights from flickering and will add a safety feature to modern vehicles and trailers with LED lighting. 30 35 6
