Hazard lights aren’t working

Hazard lights require the USB-C version of the Lumos Remote, with your remote and compatible devices set up on BLE.

The feature must be enabled in the app. You then use either one of the remote’s turn buttons, held for two seconds, to turn the hazard lights on or off.

Work through the checks below.

1. Check the remote’s charging connection

Only the square Lumos Remote with a USB-C port supports hazard lights.

These remotes do not support the feature:

• The round Remote Lite.
• The older square remote with charging contacts, also called Pogo Pin.

The two square remotes look similar, so check the charging connection rather than the shape alone.

You can still use supported scenes and synchronized power controls with an updated, compatible 2.4G setup.

For compatibility details, see Which new features can I use with my devices?

2. Make sure the BLE setup is complete

Having a USB-C remote does not necessarily mean it is already using BLE firmware.

Check that:

• The remote has BLE firmware and is paired with the app.
• Your compatible helmets and lights have completed their BLE updates.
• The remote and devices are paired with the app on the same phone.
• The helmets and lights are powered on and nearby.

Updating the remote alone is not enough. A helmet or light left on 2.4G cannot communicate with the BLE remote.

Scene synchronization working does not, by itself, prove that the setup is on BLE—scene features also work on compatible 2.4G devices.

See How to upgrade your USB-C remote and devices to BLE.

3. Check the Hazard lights setting in the app

1. Open the Lumos app.
2. If the remote is asleep, press L or R once to wake it.
3. Keep the turn signal active until the remote reconnects to the app, then cancel the turn.
4. On Dashboard, tap the connected Lumos Remote card.
5. Make sure Hazard lights is enabled.

Use the Hazard lights setting, not the separate Auto brake setting.

The app switch enables the feature. It does not start the hazard lights flashing.

Enable Hazard lights in the connected USB-C remote’s settings, then use the remote to activate them.

I cannot find the setting

Check that you are opening the connected remote’s card, not a helmet or light card.

If the remote is missing, not connected, or has not completed its BLE setup, see My remote is missing or stopped working after an update.

4. Use the correct button action

With the feature enabled and your devices powered on:

1. Press and hold either the left or right turn button for two seconds.
2. Release it.
3. Check that the left and right turn signals flash together on your compatible devices.

Use one button, not both.

To turn the hazard lights off, hold either turn button for two seconds again, then release it. It does not have to be the button you used to turn them on.

Holding both buttons is used for remote pairing, not for activating hazard lights.

A short press controls a turn signal. 

A two-second hold turns hazard lights on or off.

Only one side flashes

Check whether you tapped the button rather than holding it for two seconds.

A short press activates the selected turn signal. Press the same button again to cancel that turn, then try the two-second hold for hazard lights.

If the correct hold still produces an unexpected result, note which devices and sides respond and include that information when contacting support.

Hazard lights work on some devices, but not others

For each device that does not respond, check that it:

• Is powered on and nearby.
• Is paired with the same app setup as the remote.
• Has completed its BLE firmware update.
• Supports the relevant turn-signal function.

Do not assume every light area on every model will show the same effect. Hazard-light behavior depends on the device’s supported turn signals.

Compare firmware versions using Which new features can I use with my devices?

If ordinary left and right turn signals also fail on those devices, troubleshoot the remote connection and compatibility first.

See My remote is missing or stopped working after an update.

Hazard lights stopped when I pressed a turn button

A short press while hazard lights are active switches to the selected left or right turn signal. Pressing the same button again cancels that turn.

This is different from the two-second hold used to control hazard lights.

For the complete operating guide, see Use hazard lights.

Hazard lights will not turn off

Hold either one of the remote’s turn buttons for two seconds, then release it.

Do not use a short press or hold both buttons together.

If the remote is not controlling the devices at all, use My remote is missing or stopped working after an update to check the remote and setup.

Still not working?

Contact Lumos Support and include:

• A photo showing the remote’s USB-C charging port.
• Your helmet and light models.
• Their firmware versions and the remote’s firmware version, if available.
• A screenshot of the Hazard lights setting.
• Whether normal left and right turn signals work.
• Whether no devices respond or only some fail to respond.
• A short video showing the button action and the lights’ response.

Do not factory-reset or downgrade your setup as a troubleshooting shortcut.
