The Yokomo SD-UNR is an underbody LED light unit built for scale R/C models, producing a focused red underglow beneath the body. The lamp cycles through nine distinct lighting patterns via a single switch, including steady on, strobe flash, and softer blink sequences for display or low-light running.
Fitting is straightforward: the switch changes modes without programming, and the compact assembly is meant to be mounted beneath the body shell so the light washes the chassis and ground. During installation, check chassis cutouts and wire routing to prevent contact with suspension or drivetrain parts. The SD-UNR offers a simple cosmetic tuning option so builders can match lighting to livery or evening events.
For builders wanting a low-profile underbody lighting solution, the SD-UNR delivers selectable red effects and easy switch control so you can adjust presentation without changing the vehicle electronics or layout.
