LED in taillight query

So I picked up some LED bulbs for my taillights (1156?). Swapped them out and put it all back and now my signals flash twice as fast like if I had a short in the wiring or something.

Is that normal for tossing LED's in? I'm wondering if this is a problem.

LEDs have almost no resistance and the blinker flasher needs this in order to work properly. When a standard bulb fails, there's less resistance in the circuit causing it to trip and blink fast AKA... an easy way to tell you have an out bulb.

 

The way to cure your problem is wire in proper ohm resistors or buy the LED bulbs with the resistors built in so everything functions normally.

 

Blinking fast doesn't bother some people since the lights still blink, but I have to say it's annoying as Hell.

Another option is to replace the flasher unit with an electronic flasher, which will flash the same rate no matter the load. Some of the "tuner" knuckle heads around here actually like that fast flashing and consider it a mod, they call it hyper flash. :/
