Transform cheap bicycle light into Joule thief bicycle light

Step 1: introduction

I want to apologize for my poor English, but i will give my best to explain and include a lot of pictures for the illustration

First of all, Im not going to explain how j.t. circuit works, or how to make one, for those information you have to look for other sources.
I will explain how to use j.t. circuit with bicycle light and convert it to efficient and relatively cheap source of light.
Ive bought cheapest bicycle light for this project (1 euro) and a small lever switch.
If you think about original version (new) it had three modes <br> <br>full brightness <br>half brightness <br>blinking
No it doesn't, on and off only. <br>I was thinking about that too, something like this <br> <br>http://free-schematic.blogspot.com/2010/02/15v-led-flasher.html <br> <br>but than it will always blink, for me its better to continually shine.
does this light have a blinking mode?
