What conditions trigger radar tail light alerts?

Different brands use different radar detection algorithms. Typically, alerts are triggered when an object approaches within 150 meters, at a 15–20° angle, with a relative speed over 10 km/h.

Please refer to your radar manufacturer’s documentation for detailed behavior.

Is Lumos Ultra the only supported smart helmet?

Yes. Currently, only Lumos Ultra is supported. We are working to expand helmet compatibility in future updates.

Why doesn’t the HUD show turn signal info from my Lumos helmet?

First, make sure Zenith is connected to your phone, watch, or bike computer. Without this connection, turn signal data cannot be synced to the HUD.
