Building integrated led rear mountain bike lights? Answered
Hi folks ,as said above , would like to install a row of red high-power leds into the rear of my bike seat post to give a hidden , high-tech look :-).
Elements of design to be considered ; to run off 2-4 AA batteries , to use 5-7 5mm leds , to use " off the shelf parts " , no hand built electronics , to have constant and flash modes , would consider adapting an existing product ( e.g. cateye light unit )
For the installation i intend to drill a row of 5.5mm holes , 25mm apart , with the led heads sealed in place just protruding the surface of the metal post. The led leads would be drawn up and out of the top of the seat post into the saddle area and is where the battery pack would be strapped in. Any electronics could be housed inside seat post or under saddle. A handle bar switch would be nice but not essential.
I feel confident about the wiring and fitting of the components ( electrician by trade ) just need a pointer with the electronics.
