Just Today, I got 4 new LED 1156 bulbs and replaced incandescent bulbs with LEDs. I turned on ignition and turned the signal. The dial turn indicator light just glow, not flashing while either left or right turn signals just flashed once then that's it. I already swapped OEM Flasher relay to LED Flasher relay (7 pins relay).. It should flash all LEDs but it didn't. I suspect that resistance was too high or Amp was too low. I tried to swap one LED bulb to incandescent bulb, sure enough it flashes like it should. I even tried Cree 7 watt 1156 LED bulb, it did flashes like normal ( It's dang bright flasher! ). I felt that it have to do with resistance inside of Cree LED bulb. I was using it for Spotlights.
Even with LED Relay, do I still have to use resistor across front turn signal wires (Right and Left) to enable it to flash normally. I would like to know what Ohm and wattage of resistors I can use? I have bunch of 1/4 watt resistors of variety of Ohms.
Assuming you have stock turn signals You have the wrong bulbs..... The front are 1157 (two function) and the rear are 1156 (one function)
I am well aware of it, I just ripped out front turn signal and installed Spotlight with turn signals. Both front turn signals now uses 1156 bulbs, no longer 1157 bulbs. Spotlight act like parking lights using 1156 bulbs as well (It's a Chinese made spotlight/turn signal). I modified the spotlight to use 1156 type Cree 7 watts LED bulbs, It's bright tho.
I think I need to add pair of resistors to cross front Left and Right signal wires in order to get it flashing by connecting ground to signal wire so monostable flasher circuity will sense and flash (I've taken apart LED flasher relay and it's different than OEM. I can easily tell it's Monostable flasher.).
this is why I leave well enough alone...my head is spinning just trying to read the first paragraph...sorry...hope you get the help you need from someone here who has found the solutuin on theirs.
I just got it figured out. I experimented with resistors by sticking two ends of resistor lead into back of turn signal connector inside of headlight cover. (connecting resistor in parallel to LED lamp). I finally got it flashing and it's 1.8k ohm. (brown grey red gold). Turn signals flashes normally now with all LEDs installed and my turn indicator in dial was really interesting... It went blink on and dimmed every flashing cycle. I thought it was so COOL!!
I secured resistors lead stuck in turn signal connectors with electrical tape. If it have problem later, I would just simply solder it permanently.
I believe that those who have LED turn signal just like I have and wanted a blink on and dim cycle on turn indicator, use pair of 1.8k ohm 1/4 watt resistors
