Use hazard lights

Hazard lights flash the left and right turn signals together on compatible Lumos devices.

With the feature enabled, press and hold either turn button for two seconds on your USB-C Lumos Remote to turn the hazard lights on. Repeat the same action to turn them off.

Check your remote

Hazard lights require the USB-C version of the Lumos Remote, with the required firmware updates completed.

Check the charging connection, not just the remote’s shape. The two square versions look similar, but only the USB-C version supports this feature.

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

If you have an older remote

You can still use scenes and synchronized power controls after updating your app and device firmware. You do not need a new remote for those features.

See Which new features can I use with my devices?

Before you begin

Make sure:

• Your Lumos app is up to date.
• Your USB-C remote and compatible helmets and lights have completed the upgrade to the new BLE connection system.
• Your remote and devices are paired with the app on the same phone.
• Your helmets and lights are powered on, nearby, and sufficiently charged.

Having a USB-C remote does not necessarily mean its firmware has already been upgraded. If you have not completed the upgrade, follow How to upgrade your USB-C remote and devices to BLE.

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

Enable hazard lights in the app

1. Make sure your updated USB-C remote is connected to the app.
2. If the remote is asleep, press either the L or R button once to wake it. Keep the remote turning left or right during this process, and do not cancel the turn until the remote reconnects to the app.
3. Open Dashboard.
4. Tap your Lumos Remote device card.
5. Turn on the Hazard lights setting.

After the remote reconnects, it remains connected to the app so you can finish configuring it. This setting enables the feature. It does not start the lights flashing—you use a turn button on the remote to do that.

Turn hazard lights on

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

Use one button, not both buttons together. Holding both buttons is used for remote pairing, not for activating hazard lights.

Turn hazard lights off

Press and hold either turn button for two seconds again, then release it.

You can use either button to turn the hazard lights off; it does not have to be the button you used to turn them on.

Hold either turn button for two seconds to turn hazard lights on. 
Hold either button again for two seconds to turn them off.

Can I signal a turn while hazard lights are on?

Yes. Press the left or right turn button once to switch to the corresponding turn signal.

Press the same button again to cancel that turn signal.

A short press controls a turn signal. A two-second hold controls hazard lights.

What if hazard lights do not turn on?

Check that:

• Your remote has a USB-C port, rather than charging contacts.
• You completed the firmware updates for both the remote and the devices you want to control.
• Your remote is paired with your setup.
• Hazard lights is enabled in the remote’s app settings.
• Your helmets and lights are powered on and have sufficient charge.
• You are holding one turn button for two seconds, rather than tapping it or holding both buttons.

If the feature still does not work, see Hazard lights aren’t working.
