Anyone using these ? Do they need resistors thnx...

 

you need to be more specific. What are you trying to switch back, the nike lights?

 

Sorry that would be my front blinkers I want to ditch the hideous halogen yellow but I don't want to splice any resistors

 

Then you don't need switch backs LEDs, just the regular would do. Yes, you need resistors for LED bulbs.
Switch backs are for day time running lights that double as blinkers. The running lights would switch into blinking mode and then switch back to running lights.
Since our blinkers are not running lights, you can't use switch back anyways (unless you mod the wiring).

 

well that sux thanks for the info
