Had a look at your survey, but seems rather strange and wouldn't have thought it would help your marketing strategy.
- Age or sex, what's the relevance to lighting?
- infrastructure - I ride in all types of roads
- Clothing - no option for reflective clothing, which I think at night time is a very good backup for failed lighting
- Averages - how do you work these out. I rarely buy lights as they last for a long time, probably one over 5 years, so the average would be very small. Better to ask what would be the maximum you would pay for a light
Had a look at your lights on the website and although theoretically a good idea, I think it would give motorists a confusing image. I expect bike to have a front and rear light attached on standard positions. Anything else, including head lights just confuse.
You don't ask if I ride in the dark? I mostly ride in day time and the only serious accident I've had which hospitalized me was in broad daylight. I don't think any clever lazor lights would have saved me.
RE usb/chargeable lights - I don't really like rechargeable lighting. Rechargeable batteries of standard AA & AAA sizes yes, but with the USB ones, if you forget to recharge or are on a long ride, you need back up. With standard battery lighting, it is easy to carry spares with you or buy from a garage on route.
I do use daytime lights which you didn't ask either.
In many ways, less is more. As long as there is something, no matter how small that the driver can see, it will help. If the driver is helped with an outline, he could be tempted to think he has plenty of room and overtake. If he can't make out if there is enough room, he is more likely to hang back.
Finally, if a rider was in a night time group ride and he took the inside position with your laser outline, it could be dangerous for his mate riding on the outside. The laser outline might indicate enough room which from a distance could tempt a driver to think there is enough room and didn't allow for a second rider to be in the same area.
But I wish you look with your project.
