However, in the fuse box neither the 15A or 5A fuses that are supposed to deal with brake lights/turn signals are getting any kind of voltage. First of all you are running 2 bulb elements on each side. So that's my question I want to know how I can do that without buying a kit. So the issue is now limited to turn signals and hazards. Doing this was less wiring than combining them. If you have a turn-signal on and you step on the brake lights, the turn signal will over ride the brake light on that side of the car. turned out to be the switch was stuck just off enuf to eliminate signals and brake lights. This is all done through the Turn signal switch on column! Thanks for the answers, I'll just buy a kit instead of risking shorting something or burning something up.. Add resistors. screwy. On yours with the seperate rear signal bulb, your signal switch does not seperate the circuit from the front and rear (they are connected together) so what you want to do cannot be done. On the output side that will go to the trailer lights, you will have the yellow wire, which will now be left turn only, the green wire for right turn only, and a red wire for brake lights only. Follow instructions included with module to crimp wires. The turn signal switch turned out to be the problem (at least temporarily). And of course you could put diode in circuit to stoplight side, and prevent any current flow at all "back into vehicle"! There was a minor impact to rear do not know if that has anything to do with it or not. however I doubt you will need this unless you have something out of ordrinary in these circuits also! This is what seperates the front turn signal circuit from the rear circuit on a vehicle with brake/turn being the same bulb. One pair to switch between turn signal and brake light function on the rear lights and the other pair to either operate the front signals if you have dual element bulbs, or to switch between park lights and signals if you have single element (and vice versa)! My hazard lights work (tail lights and turn signals) B. Turn signals are a rather simple electrical circuit involving just a few components: lights, relays, flashers, turn switch, indicator, and wire. Then you'd have to encapsulate the components so they don't get shorted out in a rain. Now it is possible for power to flow towards trailer, but can't flow back from trailer circuit into the other circuits (and back to other stuff in vehicle)! Or simply put you have power to trailer when turn signal blinking (and stop is out of circuit)-- when not using TS, - the stoplight is providing power and "no blink action"! I use one on my motorhome. Check that its getting juice with your meter. My third brake light still works. Brake Lights do not turn on when brake is applied 3. This picture shows you the wiring for the 1-filament configuration. Since your turn signals work but the brake lights don't, I would check your brake light switch and make sure its ok. The brake light circuit can be a part of the turn signal circuit in some vehicle models. It can be difficult to create a turn signal system. The brake and tail lights system in many cars is a simple wiring system. The park /tail/run lights are on 2 separate circuita, and run direct to railer! Now if something should somehow happen that you would get some kind of adverse reaction, it is totally possible to isolate circuits on each side by using a couple diodes on each side! Done! In other words, when the turn signal switch is centered, the brake light switch sends power to it and through it's contacts (the T/S switch) to the two brake light filaments. There are several tricks if you are willing to "stretch the envelope! (About 15% of the time) OR... 3. What you have to do is make the brake light wires and the turn signal wires combine in a way that the turn signal wires can override the brake signal. On the 4-pole pin for the yellow wire you should detect a steady signal when the brake is pressed and an on-and-off signal when the left turn signal is on. Get your answers by asking now. So there should be no problems with anything on truck as far as affecting operation of all the other lights! i changed - Answered by a verified Technician. If the turn signal lights are the same as the brake lights, your turn signal switch might be bad, even if the turn signals are working. The diodes probably cost about $1 each, get the "heavy duty" ones like used in battery chargers and power converters - need 12-15 volts and at least 2 amp rating! You could make your own using a few generic automotive relays that are dual-throw type (have a normally open and a normally closed contact, most have only the normally open contact). A diode works like a "one way gate" it allows power to go through one way, but not the other!

Doors do not automatically lock when I start driving, so dome light has to be manually turned off A. Believe me it's easier to buy the kit and less expensive too. With both the "out" ends tied to gether and going to trailer, - each "in" one is hooked to diferent wires (from ts, and stop wires) on truck! I did this on a Mercedes sports car in 70s, when all the electronic stuff was not so common! as brake lights not working (except 3rd) almost blew off the flasher as an issue. You consent to our cookies if you continue to use our website. However, head and tail lights both work when they're turned on. Check the switch’s wiring diagram and find the single wire that establishes a connection between the brake light and turn signal switches. The plug that plugs into the switch has ~12v current. Sometimes this varies and the turn signals and brake lights come on very dimly. Check for a burned fuse, then I would look at the wiring in the dash. This puts "low voltage" to stoplights, and full plower to which ever side it is turned to-- since resistance is in stoplight circuit, very little current flows back down stoplight circuit to cause other side to be bright enough to confuse people behind you !-- Thus turn signal is brighter than stop, - so you see the turnsignal blinking on one side and brake "on"- on other! lucky for me I didn't have to work on too many of them. The trick is to "double up" stop and turn on one circuit and use other for park/run lights!

How To Make a 2-wire Tail Light Display Running Lights, Brake Lights, and Turn Signals This is a method to display more light back there than the typical stock single tail and brake light by putting the turn signals to work as running and brake lights. Turn signals do not flash at all, both directional indicators on the dash come on dimly when the brake is pressed, and the brake lights do not work. We tested the brake light switch, there's continuity when the brake is pressed. To most drivers, turn signals seem pretty simple: There’s a lever that makes your signal lights flash. Also installed new backup lights under the bumper. Turn Signals do not turn on when switch is flipped-no lights or sound 2. There is a failure that is common to the operation of both circuits. Basically you'd have to buy all the components that are inside the kit and build your own convertor. Separating Turn Signal Here I will describe how to separate the turn signal from the brake light. Why did I do this? I removed the stock rear housings, cleaned the screws for proper ground and thoroughly cleaned the socket terminals for good contact. And together with the brake light, the tail light is lit as well. Thank y'all! Weird & Wacky, Copyright © 2021 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company. My explorer has seperate turn signal and brake lights and does not have a trailer wiring harness plug so I started wiring it myself and been trying to figure out how I can make it so that the turn signal and brake light is one so it matches the trailer wiring setup. with the test light key on turn on left or right turn signal, at the connector plug on the steering column probe each of the wires you should have 2 of them flashing one flashing,,, needs a new switch two flashing,,, bulb bad or wiring prob form the connector to the back lights This is achieved by routing the power to the turn signals through a flasher or module that sends pulses of power to the lights instead of a steady stream. Visualize a "Y" laying on its side, -- power from stop, and turnsignal hook on the "forked side",--- the trailer stop/turn (wire to bulb) hooks on the single side! But since there is only one brake light wire at the bike of a motorcycle (compared to trailer wiring), when I wire the brake light to each of the LEDs, it effectively links the brake lights to the turn signals. I have checked the fuses and the bulbs and they are both fine. Back in November my stop lights were no longer working while the emergency flashers, turn signals, and 3rd brake light were still working. what the hell would that have to do with brake lights...right?
