Alphard Vellfire 30 LED Reflector power outlet harness
Tail lamp LED reflector parts with dimming unit 

 

This is a"power extraction kit"that is convenient for retrofitting LED reflectors. 
 LED reflector/small illuminance can be dimmed freely with the dimming dial, and the brake is 100% lit in conjunction 
When you do not need to turn ON the LED reflector, you can also use"ON ⇔ OFF switch to switch ON and OFF". 
 Since it is a simple coupler-on type, it will not damage the genuine harness on the car body side. 
 All you have to do is insert it between the tail unit and the body coupler.
