I just ordered some two wire led lights for my high beams and turn signals. My question is if i have i no load flasher for my rear turn signals, which are led, will this work the led dash bulbs as well or do i need to add a resistor to the bulb itself? If i do need to add a resistor can someone post a pic of what it should look like and what size i should use. I did see on here somewhere to use a680 ohm-1000 ohm resistor. Thanks.
