Cosmo Connected - Cosmo Moto - Motorcycle and Scooter Helmet Light - Removable, Smart and Connected Rear Light - Brake Lights, Automatic Fall Detection, Journey Sharing - Black

Works perfectly and works when engine braking also 👌

Hard to see what it does on engine braking but feel safer with it on especially down M27

The Cosmo Connected is a great idea, and works well for the most part, but there are some issues. First the good - it is very bright, making you more visible to other road users. I ordered a black unit because the Amazon page said the white one was out of stock...but when it arrived, I opened the box and found a white unit inside. Nice surprise considering I wanted the white version to go on my white helmet, but if I'd wanted the black one I would have been a bit annoyed. Now for the slightly dissappointing stuff. First, the accelerometer/braking functionality (which make the light illumiate as if you're braking) is too sensitive and can activate even when just moving your head around. The app that you need to download to use the Cosmo/change settings is very poor. You can change sensitivity settings within the app, but they don't really make much difference. Finally, why there is no option to disable the accelerometer and simply use the Cosmo as a running light makes no sense, especially since the functionality is so hit and miss. It's still worth a purchase at the current price (£60), especially to give more visibility to you as a rider during the winter months, but there are some glaring issues which could probably be sorted with firmware updates.

Good safety addition increasingly visibility particularly to higher seated following traffic, Trucks and Vans. Hopefully decreases risk of been rear ended. Sometimes difficult to turn on. Battery indicator requires connection to app which is a bit of a faff. It easily connects to magnetic base with helmet on.good value alterative to e.g brakefree system.

The light unit is well made & matches the black gloss paint on my LS2 flip front helmet, the led's are very bright when in braking.
