Concept Bikes & Bike Innovation - for better or worse

The Kickstarter clearly states they can be set to any colour. Any rational person would set them to red. Presume they change to amber when being used as indicators.
I like the idea, but ugy as sin. Why make them in every hipster colour but not chrome or raw?

'Any rational person' isn't justifiable reasoning in a design process. People are massively irrational a lot of the time and just giving them the option to choose the correct option does not mean they will. I bet if it makes it into production a large percentage of purchasers will be on the road at night with different colours or rear light showing, especially with the speedometer function.

As a designer, the creator of this project should be aware of the significance of different coloured lights on the road, both in terms of legislation and reactions of the user and other road users around them. It should be one of the first things that they should be looking into when they start designing anything to do with a bike light. With that in mind they should be well aware that the only acceptable colour for the rear facing lights to be in road going operation should be red, with flashing orange as an option for indication. With that taken into account before looking into any further potential usage modes, it should be clear to the designer that if they want to make further colour modes available to the user they need to make them aware that using the light in any of these other colour modes on the road is potentially dangerous and could well make their bike unfit for road use depending on the laws in the area. But having taken that into consideration the designer should really be assessing whether the additional interest generated by the extended feature sets of changing colours is worth putting a product into the market that has the potential to put the user at risk even after fully informing them of the reasons that it could be putting them at risk.
