BT blink sound for bikes
Needed a simple beep or sound generator and a bluetooth sending device with a common BT protocol in a water resistant housing on base of 12 V and a trigger input (or two).
The trigger could be connected with the blinking relais, controling light or the two blinking lights.
-> EASY, SIMPLE but VERY valuable for bikers, because they could hear the blinking INSIDE the helmet, while OUTSIDE beepers are forbidden for being too loud for the surrounding to be heard inside the helmet while cruising fast speed.
I think this gadget should be sold very often, because its very cheap to built and easy to implement into the bike by nearly everybody. On the other hand practically very interessant for every biker.

I have no idea about BT blink sounds for bikes. You can check https://10ebikes.com/recommended-electric-bike-accessories/ this list, there are accessories that can be added on bikes.
Can I get these at walmart stores?
