Updates, I decided to smoke out all the lights and run all LED bulbs in my markers, tail, stop, turn, reverse and front as well. As normal nothing goes as you figure it would. I started by reading posts and doing my research. Ordered the lights needed for the replacement from Amazon (JDM Star bulbs) and got the new flasher for them from E-bay (2-Prong LED compatible Flasher EF32RL).
The flasher is reverse wiring so I made an 8” pigtail flopped the connections and then grounded it to the body, turn signals work all around, good to go. NOPE! On the rear lights with the parking/head lights off the bulb was extremely dim light (should be off) but functioned with the flasher and brake, turn on the headlights and the tail lights will be bright like the brake is being pushed, so no brake light when the pedal is pushed. So little more research and nothing really talked about this that I could find. Here’s what I did to fix this issue.
Bought 2 - 6 ohm resistors for the rear only. Tied these into the ground and the LG/Br wire reinstalled the bulbs and tested, everything now works as it should. Lights off, on, turn, brake, all functioning. I’ve read that a 3 ohm resistor is used on all 4 turn signals but also that the LED Flasher would work without the need for those. Come to find out that the rear would need them anyway for all lights to function properly. Thinking that after running it like this for a while and testing if there are any problems I’ll run the resistors at all 4 lights.
