Last Updated on August 6, 2018 by Swagatam 28 Comments. The turn signal on the driver side also has a YEL & WHT/BLK wire. 6" x 2-1/4" Rectangle. The following figure shows how to modify the above car side marker further such that it always flashes in accordance with the turn signal pulses: The 470uF makes sure that the PNP TIP127 remains completely disabled while the turn signal is operating. As Abel Labour stated earlier it does flash out of time. At night marker on and when the turn signal flashes, it glows. There are 2 wires going to the side marker light. I can buy the required parts and wire them up as directed. If your vehicle has a 2 wire system which uses the same bulb for the brake and directional signal, you would need a vehicle to vehicle converter, part # 118158 installed on the trailer. These contain the brake lights, turn signals, reverse lights and parking or marker lights: 1. The circuit taps into the blink turn signal line to determine when it is pulsing causing the car's turning light to blink. The skirting is totally cosmetic and the underside is completely open. A wire will be run from the front LED Side Markers to the rear LED Side Markers giving them the same functionality. Attach the YELLOW wire to the bulb positive. Turn on just the marker lights and remove the marker bulb and using a meter determine which wire has 12v. There is a faint glow of the LED lights. If you are using a regular bulb, you could have done the floating ground method. $19.98 $ 19. The circuit taps into the blink turn signal line to determine when it is pulsing causing the car's turning light to blink. yes that's' possible, reducing the 470uF to some lower value, say to 220uF or 100uF will correct the issue. A marker light can be used as a turn signal, but may not be as bright as the original, depending on the bulb. I think the solution is running the side markers with constant hot lead and controlling the blinking off or blinking on with some kind of control circuit on the side marker's ground. The other circuit does both turn signal and brake lights. Cut the positive lead to the marker light about 3" from the light. Your email address will not be published. Brake lightsare the two red lights on each side that flank the the central red marker light, and are illuminated when your press the brake pedal. Step 5: Route the wires from the side mirror all the way to the front engine bay and tap the wires to the front turn signal light, the front side marker lights on the fender, or the mirror assembly turn signal (if so equipped). And splice the black wire to the turn signal wire (the part of the black wire that is on the same side of the cut as the marker light connector). The blue circles are the side marker lamps. Connect all of the wires according to the new wire configuration. Hello, you can possibly try the following idea: Take another TIP127 BJT, connect its emitter with the emitter of the existing TIP127, base with the collector of BC547 through a 10K resistor, and then use separate diodes (1N4007) with the collectors of these two TIP127 such that their anodes go to the respective collectors, and the cathodes join together and connect with the side marker LED's anode, while the cathode of the LED goes to the ground, I hope you understood the connections…. After changing to an LED compatible flashing unit, everything is working correctly. The idea was requested by Mr. Jerry Klein. Turn signals on either side of the vehicle can be wired in series, much like the bulbs on a strand of Christmas tree lights. Since the ground reverses, I can't run LEDs on the front and sides. The relay is simply switched on by the power to the turn signal and that in turn powers (or interrupts) the other light(s). Ram, no modifications would be required in the circuit, for the LEDs just use 2 LEDs in each string without any resistors. I am using LED light bulbs. Blinks as correctly. They will combine the brake wiring and the turn signal wiring so they will work. Mission completed!! HelloStumbled across this thread doing a little research as I consider changing my car lights over to LEDs. Now if the turn signal lamp is switched ON, the relay driver BC547 would start pulsing in response to the acquired signals from the turn signal source. Discussion Starter • #1 • Nov 5, 2015. A wire will be run from the front LED Side Markers to the rear LED Side Markers giving them the same functionality. Is there a way to have it turn back on after voltage reaches a certain threshold of approximately 10 volts or higher. I wanted to have my 100W  7 amp fog lights work off a dimmer so that I could tune them in to the exact lighting requirements. When when applying a left turn signal, the left marker extinguishes, the left LED turn signal flashes, goes off; and the alternating marker/turn signal flashing continues until the left turn signal is removed. Pull out the side marker and disconnect the bulb socket from the side marker: twist and pull. the 10K value is dependent on the relay coil current…so you can tailor the value accordingly, however a pot is not recommended and is not necessary, it must be a fixed resistor. Attach the RED wire to the marker light source positive. OK great, in that case you can consider of changing the TIP127 with a smaller transistor such as a 8550 or 2N2907 for making the design more economical and compact, I tried different combinations of capacitors and resistors which helped. I have updated the diagram, please check it out. The previously indicated relay coil along with the diode will no longer be required and could be eliminated, and the collector of the BC547 only hooked up with the base of mentioned TIP127. marker lights as turn signals - First let me say hello to everyone. However during night time, the positive line of the side marker would have no positive supply, in this situation whenever the relay would be activated in response to the turn signal pulse, the TIP127 also being activated (via base 10k resistor) would pass the positive from the turn signal feed to the side marker via the N/O contact of the blinking relay....this would make sure the side markers yet again blink as proposed in the above request. I am trying to use this circuit to make my side marker lamp to flash on and off when the turn signal lamp are activated. On the V-Strom, the left and right turn bulbs each have two wires.
