Met unveils glow-in-the-dark helmet

Luminescent lid emits light for up to two hours

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.

I'd suggest that a hi-viz festish is better than a black one.

Clearly most drivers are looking.
It's a bit gimmicky. Id have made it 100% reflective rather than black.

Oooh yes, much more hi viz items to add to your existing plethora of hi viz. Entrench that hi-viz fetish. 

The drivers aren't looking anyway.

Does anyone actually think that glow in the dark material will actually make anyone significantly more visible? I'm willing to be proved wrong, but I'd be very surprised if it does!

I may be wrong, but I've been observing that a helmet mounted light tends be perceived as being further away as the rider actually stands. In some situations you can't see the rider’s silhouette, neither can you judge the distance by the size of his light.

Combined with a primary light at "regular" height this a less problematic.

£190 for a piece of polystyrene that offers no more protection than another piece of polystyrene costing a tenth of the price.  But it has some comfortable straps, an integrated light and some stickers that will easily outshine the luminescent material they've added.

It also has a design that means the wearer's head can catch on objects as he slides across the road, rather than a smooth, rounded design that won't.

People actually buy this?
