This is an optional Traxxas LED Light Bar Set and is intended for use with the Traxxas Summit. Now you can blaze even brighter trails! The new Accessory Light Bar replaces the Summit?ÇÖs chrome roof light bar with a high-intensity 4-LED lighting system. Fully assembled, pre-wired, and ready to install, the light bar features vivid white LEDs in mirror-chrome housings for an amazing display after dark. The functional LED light bar kit delivers a flood of light for real-world looks and go-anywhere driving after the sun sets. The light bar installs easily with no wiring modifications required; the included Y-harness simply plugs into the Summit?ÇÖs factory lighting system. Photo-illustrated instructions and zip-ties are included for a fast and clean installation.
