The MadDogRC KOH 4" LED Light Bar is the perfect light bar to finish off your rig! This light bar features six Red, three amber and three blue LEDs, pre-wired to a custom designed light controller. The controller hooks in between the ESC and receiver, and provides tail/brake light functions, with flashing blue and amber lights, giving it an increased scale appearance on the track, or on the trail.

The lights are 3S compatible and mounted in a precision machined aluminum housing, with clear epoxy potting that creates a waterproof housing assembly. Plus, the housing is tapped for M2.5 hardware, allowing plenty of options for creative mounting in your custom applications. This light bar does not include a mounting kit, but is compatible with the Ultra-Bright Light Bar Bracket Kit (MDC-MDRC056) and HD Light Bar Bracket Kit (MDC-MDRC072). Package includes one KOH light bar with factory installed light controller.
