Created for simplicity, these boards feature ultra-bright Green LEDs to illuminate the throttle panel. A 12v input and dimmable power them via a PWN Dimmer (not supplied). These are simple: remove the old plate and fit this one instead. You can see how cool the throttle plate becomes from the last photo when it is lit in full green. 
 
Please Note: This throttle panel does not come with this PCB and requires purchasing separately.
