One part signal booster should be mounted within 5 feet after a light, then you can add up to 60 feet of spacer cable to make a jump after the signal booster.  This signal booster part comes in black color only.  The signal booster is exactly 12" long, and looks like a pebble light, but does not emit any light.  This signal booster can be used on RGBW or RGB light chipsets.
