Product Information
The Hi-Beam Interface is a CAN-Bus interface that provides two active low-level outputs. When used alongside an automotive relay, you can add additional high-current light sources and/or any other accessory, controlled via the vehicle's high beam controls. The data is decoded from the vehicle's CAN Bus and used to switch power to the connected accessory.
The Hi-Beam provides 3 output options: a constant output, a variable output, and a 'follow me home' mode triggered by successive high beam flashes. Its plug-and-play nature ensures easy installation, making it an ideal solution for vehicles requiring additional lighting for working at night.
Product Application
BMW 5-Series (e-Drive) 2018 - UP
Prior to Installation
Read the manual prior to installation. Technical knowledge is necessary for installation. Please ensure you use the correct tools to avoid damage to the vehicle or product. Connects2 cannot be held responsible for the installation of this product.
Installation
- Begin by removing the side panel using a panel removal tool. Undo the screw holding the main dashboard trim. Once free, use the panel removal tool again to remove the dashboard trim.
- With the trim removed, undo the 2x screws holding the speedometer in place. With the speedometer free, unplug the main 12-pin power connector.
- Connect the 12-pin molex connector to the Hi-Beam interface.
- Attach either the Hi-Beam 1/ Hi-Beam 2 output to the additional accessory (via automotive relay) dependent on the desired function (see ‘Functionality’).
- Connect the female connector to the back of the speedometer and connect the male connector to the main power connection.
- Turn the ignition on and test the functionality of the Hi-Beam interface with the additional accessory.
- When successfully tested, reassemble the dashboard. This will complete the installation process.
Connector Profile
Connection of the Hi-Beam interface is made on the harness that plugs into the rear of the vehicle's speedometer.

Functionality
Hi-Beam 1 Output:
- With ignition on & engine running: this output follows the state of the high beam CAN signal. If the high beam is on, this output will be on.
Hi-Beam 2 Output:
- With ignition on & engine running, this output toggles each time the high beam is flashed. After the first flash, this output will turn on and stay on; after the second flash, the output will turn off.
Hi-Beam 1&2 Output:
- With ignition on & engine not running, the output becomes 'follow me home' with various durations. The time countdown is initiated once ignition is turned off (see "Programming for ‘Follow Me Home’").
Programming for ‘Follow Me Home’
The duration of the ‘follow me home’ function is determined by the number of 'high beam' flashes within 30 seconds of turning the engine off but still having the ignition remain on. After 30 seconds, the interface no longer samples the high beam status to adjust the ‘follow me home’ timer.
Flashes must be no more than 1.5 seconds apart; any longer and the count is disabled.
- 1 flash = 30 seconds
- 2 flashes = 60 seconds
- 3 flashes = 120 seconds
- 4 flashes (max) = 300 seconds
With the required amount of flashes initiated, turn the ignition off and remove the key. The additional accessory will now remain active for the above timeframe.
If the additional accessory fails to function after the vehicle is turned off, turn the engine back on and repeat the process, ensuring you stay within the required time limits.
