I decided not to go LED & picked up a brake light/license plate mount & new turn signals all of which are incandescent. 3. There are complicated ways to wire in multiple relays to do it, and aftermarket units that will do this but there is an easier way A quick and cheap way that works just as good is a tail light wiring converter for trailers. The 12V power from both the Stop and Turn signals are OR connected by high current schottky diodes (D1 & D2) and fed to the drain of a P-Channel MOSFET (Q1). Keep in mind that vehicle LED brake lights may require pull down resistors. electrical system. Official sources of fitment information https://sylvania-automotive.com andhttps://www.automotivebulbfinder.com/philips/. So far I can get the rear brake light to light up as just rear light but it wont go bright when i apply the brake. From there it goes to the stalk on the steering column.

Some have the tail light wire running through them (4 wire into 3 wire), and some don't (3 wire into 2 wire). When the fuse blows, electric power to the turn signals will be shut off entirely. 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. A tail light relay is a device that allows the rear lights to be turned on without having to flip the switch for the headlights. A wire runs from the flasher relay to the turn signal switch and another from the brake light switch to the turn signal switch. While I believe that the potential for circuit failure is low, it is important to recognize the symptoms. the new unit, they should match identically.
