My luck I bought a set off a local for 140$ he had them on his car for 2 days and he blew the motor. I went to install them today and i put them on and turned on the full lighting of the car to test them. Only 1 lit up and the other didn't so i said w.e I had to go to school i would mess with it when i get home. I'm messing around with them thinking its a bad ground and low and behold it starts flickering and goes out. Now both don't light up. I step on the brake pedal and the LED's work so the leds aren't dead. I know to run a lower voltage you need a resistor of some sort for the running lights but im not sure where to get these or if this is the problem and because i bought them off some guy spyder won't even help me.Someone please help before i shove these up the guys *** who i bought them off
