Add scale lighting to your 1/18 scale TRX-4M Defender for an extra layer of fun and good looks. The Pro Scale Lighting Kit adds working headlights, tail lights, brake lights, and hazard lights that respond precisely to your inputs. Installation is quick and easy because the programming is already built into the ECM-2.5™. Just install the lights in the body and plug a single wire—that’s all there is to it! Pro Scale lights are built to handle all weather conditions with fully waterproof construction.
