In an effort to reduce the load on the under dash electrical system and reduce the likelihood of burning my car to the ground, I have attempted to change over to LED Tail lights on my 74 Duster. I did an amp meter bypass which was simplified by the fact that my car came with the 60 amp alternator from factory (Factory AC car). On the 60 amp alternator equipped cars the alternator wiring did not go through the bulkhead as it did on most cars. I also fire the headlights with relays controlled by the wiring that used to supply the headlights themselves. I know this is not new or groundbreaking, I just wanted to provide some history.
I was recently proving out all my wiring and I found that I did not have signal lights. I had brake lights, park lights, hazard lights but no signal lights. I switched the flasher with the proven working flasher in the hazard lights and it did the same thing. After messing around a bit, I noticed that when I checked for voltage at the signal light switch with my test light, the signal light would work properly while the test light was part of the load. I am assuming that the flasher needed the additional load of the test light in order to operate.
After extensive research (Mostly stalking Dan Stearn’s posts on this site) and a couple emails back and forth with Mr Stearn, the following is the list of parts I chose to use. With these parts I am very happy with the added brightness of all the lights.
Does anyone have any idea what I can do to make this work? I don’t like the idea of adding unnecessary load which I am sure will solve my issue. Also I tried it with standard incandescent bulbs in the front signal lights and this fixes it but also defeats the point of why I was doing this whole upgrade in the first place. SLANTSIXDAN, I hope you will chime in on this.
- NOVITA EL12 FLASHER (for both signal and hazard flashers)
- PHILLIPS 1157 LED STOP/TAIL (red) brake lights
- PHILLIPS 1156 LED (P21) back up lights
- PHILLIPS 1157 LED STOP/TAIL (for front signal lights)
- PHILLIPS 194 LED (for side marker lights)
