This idea started when I found this small oil lamp in our landlords storage shed. I have been working on bikes for a while now and I remembered that I had this old incandescent bullet light knocking around. This thing was pretty useless; it wasn't very bright and the batteries were not held in place very well, making the light cut in and out as you rode. I had been thinking about doing an LED conversion on it because I liked the style of the light so much, but the idea just seemed a little boring. Enter the bike lantern.
Note: I apologize for any confusion it may cause, but you will notice work being done on two different versions of this. The first was with the found pewter lamp and the second is with the brass one ordered from the internet. I have them mixed in the steps but the brass one is the final product that I have used for three months now.
*Actually I would still keep the commercial light as the candle-power of this project is pretty easy to quantify; It's one. Also check your local laws for bike regulations. We get pulled over pretty regularly here in Berkeley for light violations and I have yet to get a ticket, although I can't wait to see what happens when I do get pulled over!
