Meh.
On the basis that this idea was floated on dragons den a year ago...is now in production and available in the uk already.
I suspect by a different firm.

Its a skull boiler type tho.
For me who runs warm normally, that is enough to put me off any consideration of its other features.
General note.
I have a £20 decathlon helmet with £15 worth of lights attached. My sole reason for a helmet is as a high level vantage point for them and worn only in bad weather, dark rides when I feel the need for more light, but I wouldn't buy an integrated light/hat and particularly not with indicators.
If the lights on my helmet fail, I replace only those, if I feel they are not doing what I need, or something better comes out, I replace only that piece. If the helmet is replaced, I do not need to trash the lights along with it and buy new ones at extra expense, if the light batteries run out I carry spare good quality ones @ £2 and they switch from bike to bike readily - I dont have a USB power source on any of my bikes nor fancy buying one or more just for power resilience for the hat JJ links to. I have free rein to pick a helmet that is best suited to my head shape and heat dissipation and is as comfortable on as it can be - with these integrated ones, I may have to compromise that comfort level to acceess the novelty features.
If helmet integrity in a minor crash or fall is a factor then my helmet itself makes no compromise to having weak spots or thinner membranes in order the fit the light units flush - accepted I may be putting a stress point in as per Schumacher Cam with an attachment but both front & rear are designed and fitted to minimise this eventuality & crash tested.
