Retrofitting Bike Light (Old Dynamo Bulb to a Battery LED)

My friend teased me to retrofit a headlight on my old bicycle, so I accepted the challenge. After spending few bucks on small soldering iron, custom switch and a new ultrabright LED flashlight, I started to work on it. First, dismantling the whole thing, picking out a bulb and other small items included in the former dynamo light.

Then I took a battery holder from a small flashlight, combining it, gluing a custom switch to the opening where the dynamo wires were running through and a bit of soldering, putting it all together with a LED light circuit board. Trying to fit it all inside and all set, new bicycle headlight ready. Ultrabright front bike light retrofitted to the former dynamo front light.
