Rechargeable Bike light set with bottle battery

This is my light set up I've just completed for the long Scottish winters complete with high power front and real LED lights and a rechargeable bottle battery. I've drawn inspiration from a couple of people who are referenced with thanks.

Step 1 Costs

Since cost is usually prominent in folks mind I'll start there. I've tried to keep these as low as possible since i consider this a prototype and intend to have a better version for next winter.

Total for this project = $25 (£15) + £24= ~£35 plus loads of left overs for another project. Not bad for a really bright light set.

1x 22mm tight focusing lens (pack of 5) $5
