CAN-Bus High Beam Interface Module – 12V / 24V Smart Trigger for Driving Lights

Overview

The Perception Lighting CAN-Bus High Beam Interface Module is a smart solution designed for modern vehicles where traditional high-beam wiring is no longer accessible.

Many late-model vehicles control headlights digitally via CAN-bus systems. This module reads high-beam status directly from the vehicle’s CAN-bus network and outputs a clean 12V or 24V trigger signal to activate auxiliary driving lights via a relay — without cutting or interfering with factory headlight wiring.

It is suitable for a wide range of passenger vehicles, 4WDs, utes, SUVs, and light commercial vehicles running 12V or 24V electrical systems.

Key Features

• CAN-bus controlled high-beam detection
• Triggers auxiliary driving lights without tapping headlight wires
• Prevents dash errors and fault codes
• Compatible with 12V and 24V systems
• Single high-beam output (relay trigger)
• Compact, sealed module with status LED
• Ideal for LED driving lights and light bars
• Designed for modern vehicles with CAN-bus lighting control

How It Works

• Connects to the vehicle’s CAN-HI and CAN-LO wires
• Monitors CAN-bus data in real time
• Detects when factory high beam is activated
• Outputs a switched 12V / 24V signal
• Signal is used to trigger a relay for auxiliary lights
• No Vehicle coding or programming required.

Technical Specifications

• Voltage Supply: 12V / 24V DC
• Output: High-beam trigger output: 12V / 24V (1 Amp Max)
• Operating Current: 20mA
• Operating Temperature: -40°C to +75°C
• Dimensions: 63 × 43.5 × 15.5 mm
• Output is trigger-only and must be wired via a relay
• Some vehicles have multiple CAN networks – a correct connection is essential
