Part 3: Adding LED Lighting

For this build, we’re keeping it simple and installing the 8035 lighting kit, which includes headlights, tail lights, and side marker lights, plus the required LED lighting module (aka “power supply”). If you want to go all out, Traxxas also offers a Rigid LED lightbar and rock lights. These are sold with and without lighting module. Since we’re installing a lighting module with the 8035 kit, our Bronco will be ready for a light bar and rock lights down the road. Traxxas makes light installation super easy, thanks to the LED-ready body features and handy tie-down spots to keep the wires tidy. One extra step for our build: since we’ve got the High Torque 400, we’ll install the required High-Voltage BEC while we’re in the receiver box hooking up the LEDs. For a detailed look at the LED install, go back to the Ultimate Trail Truck build.

The 2262 High-Voltage BEC kit includes the 2260 BEC plus the required receiver box lid and new seals. Installation is pretty straight forward since Traxxas includes all the required parts in the kit. For a detailed look at installing the High-Voltage BEC kit, refer back to part 3 of our Ultimate Trail Truck build.

The 8035 light kit includes the required LED lighting module. Traxxas also offers the kit minus the module (8036) if you’ve already got a module installed in your truck as part of another accessory package. Mounting the module is easy since the bosses are already on the chassis.

The lighting module and the High Output BEC both need to plug into the speed control. A Y-harness is included with the BEC just for this reason. Be sure you're plugging into the high voltage wires from the ESC and not the fan output. The headlights and front marker lights install from behind the grille.

The LEDs plug into a distribution block that attaches inside the body using a mount that captures the plugs. Plug the LED’s into the block first, then install the block in the mount, then install the block into the body. Use the zip-tie loops to keep everything tidy. Now we're ready for night driving. The LEDs switch on and off with the speed control as long as they are plugged into the power module.
