lerch641 Posted October 21, 2014 Share Posted October 21, 2014 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.

ferrariowner123 Posted October 21, 2014 Share Posted October 21, 2014 Yeah its normal the led's run on a different voltage I think. The place you bought them should see a voltage adjuster (a resistor) so that way the car doesn't skitzo on you. -Kyle 1 Link to comment Share on other sites More sharing options...
Kingman Posted October 21, 2014 Share Posted October 21, 2014 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. Link to comment Share on other sites More sharing options...
01Pathmaker Posted October 21, 2014 Share Posted October 21, 2014 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. Link to comment Share on other sites More sharing options...

Karmann Posted October 21, 2014 Share Posted October 21, 2014 As said the voltage difference causes this. I love LEDs but haven't swapped my blinkers to them until they have a resistor built in, and DOT legal ambers. Link to comment Share on other sites More sharing options...
lerch641 Posted October 21, 2014 Author Share Posted October 21, 2014 Thanks guys, I'm not great with electrical so I just wanted to make sure they aren't going to fail. Link to comment Share on other sites More sharing options...
