This is the essential Power Regulation Module for the Traxxas TRX-4 lighting system. In the world of modern RC crawlers, you cannot simply plug LED lights directly into the receiver or battery, as the voltage is often too high (6.0V - 11.1V) and will burn them out instantly.
The TRX8028 acts as a transformer. It takes the high voltage from your battery (via the ESC's red JST plug) and steps it down to a safe, constant 3.0 Volts (DC). This ensures your LEDs burn bright without overheating or popping.
Key Features
-
Regulated Output (3.0V): Specifically designed to power standard Traxxas LED light kits (Headlights, Tail Lights, Rock Lights).
-
Warning: Do NOT use this for high-voltage light bars (like Pro Scale or 3rd party 12V bars) unless they are specifically designed for the 3V rail.
-
-
3-in-1 Wire Harness: The output side features a splitter cable that allows you to connect 3 separate LED accessories at once (e.g., a Light Bar, Rock Lights, and a Bumper Light).
