All the lighting control of a full-scale truck is at your fingertips with the Pro Scale® LED Light Set for your TRX-4® Sport. Turn the headlights on and off and select high or low beams. Signal for turns with automatic cancellation or put on the hazard lights. The brake lights glow when you slow or stop. Hit reverse, and backup lights glow automatically. For maximum power and convenience, add Traxxas Link and the optional Wireless Module (Part 6511, sold separately) to configure your lights right from your iOS or Android device. The Pro Scale system makes it easy.
