Enable automatic brake lights

Automatic brake lights use motion detection to activate brake-warning lighting on compatible Lumos devices when braking is detected.

This is an existing Lumos feature that you can continue using with the new app. How you turn it on or off depends on your remote and connection system.

The feature controls your lights—it does not operate your bike’s brakes.

Choose the instructions for your setup

The two square remotes look similar. Check whether yours has a USB-C port or charging contacts.

For help identifying your remote, see Pair and set up your Lumos Remote.

Use the app with an updated USB-C remote

Before you begin

Make sure:

• Your USB-C remote and compatible helmets and lights have completed the BLE upgrade.
• Your remote and devices are paired with the app on the same phone.
• Your helmets and lights are powered on and sufficiently charged.
• Your remote is securely mounted on your bike.

If you haven’t completed the upgrade, see How to upgrade your USB-C remote and devices to BLE.

Turn automatic brake lights on

1. Open the Lumos app.
2. If your remote is asleep, press either L or R once to wake it. Keep the turn signal active until the remote reconnects to the app.
3. Once connected, cancel the turn signal.
4. On Dashboard, tap your Lumos Remote card.
5. Check that Remote mounting position matches how your remote is installed: horizontal or vertical.
6. Turn on Auto brake.

This enables automatic brake detection. It does not make the brake lights stay on while the bike is stationary.

Turn automatic brake lights off

Reconnect the remote if needed, open the same settings page, and turn Auto brake off.

The new app provides an on/off switch only. It does not offer brake-light sensitivity adjustment.

Use Auto brake in your updated USB-C remote’s settings to enable or disable automatic brake lights.

Use the device button with an older Pogo Pin remote

If you use the older square remote with charging contacts and your devices remain on the original 2.4G system, change the setting on the device itself.

The new app cannot turn automatic brake lights on or off for this setup.

1. Press and hold the power button on the helmet or light until the device enters pairing mode.
2. While it is in pairing mode, press that power button five times in succession.

This toggles the automatic brake-light setting: off becomes on, and on becomes off. Repeat the same procedure when you want to change it back.

Use the device’s power button, not the L or R buttons on the remote. Pairing-mode indicators vary by model.

For the older Pogo Pin setup, enter pairing mode on the device, then press its power button five times to toggle automatic brake lights.

Check the result before riding

After setup, with your devices back in their normal operating mode:

1. Check that your remote is securely mounted and your compatible devices are powered on.
2. Test in a safe, traffic-free area.
3. Have another person observe the lights as you slow down and brake normally.
4. You can also manually rock the remote back and forth to check whether the brake lights on the device turn on or off.

Keep your attention on riding rather than turning around to watch the lights.

The feature responds to detected motion. Pulling a brake lever while the bike is stationary does not reproduce a riding test.

What if the brake lights do not respond?

Check that:

• You are using a compatible Lumos Remote, not Remote Lite.
• The remote and devices are charged and correctly paired.
• The devices use the same connection system. Original-system devices cannot communicate with BLE devices.
• You used the correct setting method for your setup.
• For the BLE USB-C setup, Auto brake is enabled and the mounting-position setting matches the remote’s installation.

If you cannot find the switch in the app, check which remote and connection system you are using. The older Pogo Pin setup uses the physical-button procedure above.

For pairing help, see Pair and set up your Lumos Remote.

If the feature still does not respond, contact Lumos Support with your device models, remote type, firmware versions, and a description of how you tested it.

Does this affect battery life?

Using automatic brake lights can increase battery use. Check your remote and device batteries regularly, and turn the feature off using the appropriate method if you do not want to use it.
