Met is offering its top level Sine Thesis in a Nightlights version that it claims is the first bicycle helmet with luminescent material injected into the exoskeleton, cam divider and size adjuster.

This material is designed to absorb light during the day which it can then emit for up to two hours when it is dark in order to provide additional visibility for night riding.

The Safe-T Advanced USB LED Light is included with Sine Thesis Nightlight. This fits onto the dial of the retention system and features six LEDs in flashing or constant modes. You also get an automatic night safe mode.

Met reckons that it’s visible up to 500 metres in urban conditions.

The Sine Thesis also features reflective stickers and logos at the front, the back and the sides, and reflective straps.

Of course, neither Met nor anyone else is suggesting that this is a substitute for good lights on your bike.
