Helmets with Emergency Stop Lights (Brake Lights)
Some modern motorbike helmets (mainly Nolans) come with their own brake light built in. It’s generally termed Emergency Stop Signal or ESS and they work because they use their own in-built accelerometer and power supply, so they don’t need to be linked with the bike. Where a crash helmet either comes with an ESS or there’s one available for it, you’ll find its review on this page.
