LED's dont work?
Yo i just bought some turn signal led's. I bought 1156 bulbs. The bulbs work in the rear turn signal spots and they work well. i will need to put in a resistor to get it not to blink so fast. BUT the LED's in the front turns just dont even work. I cant figure out why. I changed them around flipped them i havent put a resistor in the front but idk would it really need a resistor to turn on?? I dont think resisting the current would make it turn on. The bulbs arent burnt out, and the normal bulb works, but with the LED, no attempt to even turn on. Any ideas?

Did you have the correct polarity? LED's are directional.
Wait - I see you tried flipping around already. Otherwise I would try it with the limiting resistor, and measure the socket with a voltmeter, comparing to the back as well.

ima try with a multimeter. its weird cause i bought 2 types of bulbs, one type works, and the other doesnt, but the ones that dont work up front work in the rear turn signals.

Install real 1156
in the rears that work and install the 1156 LED's in the front and see if they work in that order.The resistors are needed to balance the system for the lamp malfunction maybe using 4 of them without balancing the system is under or over loading the circuit.
