You may have to put in a load equalizer due to the fact that LED bulbs take far less current to operate. The flasher going faster is a clear indication. The system doesn't think there is a bulb there. Check out http://www.superbrightleds.com and read the article about it there. You can purchase the item/s necessary to fix the problem from them.

 

Interesting, I had a similar issue.

 

are you talking about one of the LED flasher module? I didn't see anything with a load equalizer on it.. or are you talking about a resister? I have a Tridon EP-35 which is supposedly compatible with LED lights. unfortunately there wasn't any change with the LED's not working though with the new flasher the bulbs didn't blink fast like a bulb/LED was out..

 

If you run the stock flasher (unmodified) w/ LEDs then you need the load resistor to trick the flasher into thinking there are high current bulbs there. If you put in a heavy duty flasher then no need for the resistor as that flasher will run the same speed no matter how many bulbs or how much current is being drawn through it.

 

I will give it a shot.. all I need to do is find the heavy duty flasher its hell of a lot easier than putting in resisters.. any idea where i could find one?

 

OR.... You could make your own LED array!!! Haha, it really isn't too complicated and it's way better than PnP LED bulbs.

The following thread has to to with an LED 3rd brake light, but I did the same thing with my front blinkers except that I used more LEDs and they are amber.

Sorry, not trying to make things more complicated, I'm just showing you a cheaper/better alternative

But as everyone else has said, resistors are NOT required if you have switched your stock flasher to an LED flasher or a heavy duty flasher. Your PnP bulbs should work if the polarity is correct, but I think it's pretty hard to switch the polarity on an 1156/57 bulb. If you can get them to light up from an external source, and your incandescent bulbs work when plugged into the socket, there is definitely something going on with your LED bulb contacts and/or their polarity is backwards.

heavy duty flasher is easy... you just need to get one designed to be used with a trailer harness. Any auto store should be able to hook you up

 

Sounds like the new flasher you got is a heavy duty unit, since it flashes the same speed regardless of how many or what type of bulbs are plugged in.
