So what I've made is a bike light with an LDR, tilt switch and Rocker switch.
The lights turn on when the light level drops below a certain amount.
The tilt switch then decides which colour lights will be on (red or white) (depicted in images below)
If positioned on the back then Red Lights will show.
If on the front white lights will show
If used in daylight then the Rocker switch will just turn the white lights on and off or if at night it will turn the lights off.


I'd like your opinions on the following:

-Size
-Design/appearance
-how marketable it is (whether you'd be prepared to buy one and for what price)
-Simplicity to use
-how much you'd pay for one

Inside my skull
Is it made from Lego parts?

It’s huge
Rear and front lights have very different requirements.
It is a be seen light rather than see by, so would only ever be a backup and what happens if mounted vertically on the front? A backup light should take up minimal space and not dominate the handlebars.
Doesn‘t look like it’d mount well on the back any place other than a seat post
Seems over engineered and trying to solve a problem that doesn’t exist.
It is an unfinished prototype.
I wouldn’t buy one.

I have got to applaud your tech skills, with a bit of refinement you could be on to a winner..

As long as I breathe, I attack.
s a prototype its big based on traditional screw connectors ?
As a marketable product you would need to get it made on a smaller form factor using pcb , the concept is ok but moving forward it needs to be miniaturized

Hello,
The product is made from two PCBs and in future iterations I would try to minimize size
please could you give feedback on the following:

-Size
-Design/appearance
-how marketable it is (whether you'd be prepared to buy one)
-Simplicity to use
-how much you'd pay for one
