Step 3: Modding Stock Taillights to be Dynamo powered
Check out the video: Click on the images above for details
I plan on using this as an Supplementary Taillight during touring or heavy traffic. I already use a very nice Busch & Muller's dynamo taillight, and i dont want to replace it with this cheap light. I did it to see whether it could be done or not, and it actually turned out very nice. You can power it both using a battery pack or a dynamo.
Actually, I got this idea from this cool instructable: http://www.instructables.com/id/LiteBack---Backpack-or-Camelback-Mounted-LED-Bike-/
While the taillight which i put together worked fine with a dynamo during initial testing, but I have not stress tested it. At worse, it may burn out and I may need resistors to run it safely with 5V. The problem is I am not really sure specifications of the LEDs, so it would be difficult to calculate the resistance. I will do a stress test tomorrow and see what happens. If it doesn't burn out, I know it will work fine without resistors.
This taillight in this project turned out rather cool. Click on the images. You will get the idea and details on how it was done. Let me know if you have any questions. You may find cheap taillight to experiment from Dealextreme: http://s.dealextreme.com/search/bicycle+tail+light
