Wireless Helmet Light with ECU

The Steelmate H3 is a wireless LED light unit that attaches to any motorcycle helmet. It receives signals from an included electronic control unit connected to the bike's lighting circuits. Riders gain extra visibility without routing wires up to the helmet.

Synchronised Brake and Turn Signals

The ECU links the helmet light to the motorcycle's running light, brake light and turn indicators. When the rider brakes or signals, the helmet unit mirrors the action automatically. This single integration step decides whether the system works as intended.

Suits Riders Wanting Cable-Free Visibility

The rechargeable battery delivers up to 18 hours of use and the adhesive mount fits all helmet brands. Ten selectable streaming patterns let the rider choose a preferred style. Buyers who need a hard-wired connection or a model without an external ECU should look elsewhere.

Questions about this item

How does the 18-hour battery life translate to daily riding?

The rechargeable battery delivers up to 18 hours of operation per charge, enough for several days of typical commuting before needing a USB top-up.

What wireless link does the included ECU use to sync with the bike's lights?

The ECU connects to the motorcycle's running, brake and turn-signal circuits and transmits the signals wirelessly to the helmet unit, so the helmet mirrors every lighting change.

How does the light attach to the helmet and will it stay put?

A super-sticky adhesive pad mounts the light to any helmet brand or model; the wireless design means no cables to route and the unit can be removed cleanly when needed.
