I installed new rear turn signal bulbs (LED's) and now every time i signal left or right, it flashes like theres a bulb that is out (double the speed). Is there any way to get it back to normal speed? reset something?? thanks

 

LED turn signals are supposed to come pre-built with resistors that control the level of power that is being used/sent. Your LED doesn't have this, obviously.

 

+1. LEDs draw very little current compared to a regular filament bulb. when no or low current is detected, the car things a bulb is out and flashes like ur describing. you can put an in-line resistor to simulate a filament bulb, or get LED bulbs with enough resistance.
