The Yokomo SD-UNR is an underbody LED unit made for scale R/C models, producing a red underglow beneath the shell. It features a single switch to step through nine lighting modes, from constant illumination to varied blink and strobe sequences for display use.
Installation is simple: select modes with the on-board switch, and locate the compact lamp beneath the body shell so the light can accent the chassis and ground. During fitment, check that the lamp and wiring clear suspension and drivetrain components and that any body cutouts align with the unit. The SD-UNR is a straightforward visual upgrade to complement model liveries and evening runs.
If you need a discreet underbody lighting option, the SD-UNR supplies selectable red effects and a no-fuss switch for presentation adjustments without changing electronics or chassis architecture.
