The Yokomo SD-FUNR is an RC-scale flexible under-neon set intended for installation inside the body shell at the front, rear and lower side panels to brighten the model's underside. Each quadrant is fitted with four chip LEDs on a flexible substrate so the assembly adapts to different body contours without PCB cutting.
Power is taken from the receiver, so plan the lead routing to a spare channel or a receiver-switched output. Because chip LEDs throw light directionally, power the unit briefly to confirm the look and orientation before you commit to a permanent fit.
Installation is easier thanks to pre-applied double-sided tape on the base; the kit items included will help shield and guide wiring as you fit the strip. The neon should be used mainly for show and visual presentation to emphasise underbody detail rather than as a functional road light.
