Homemade Halogen Bike Light

Step 3 Battery Casing

Yes, I did actually make this case from scratch from pieces of aluminium lying around in my garage fixed together with pop rivets and nuts n' bolts. You can use anything you want for this, as long as it isn't too big but still houses the batteries and connections. I have yet to make this box watertight, and will be sending pics once I have a solution, oh, and a lid for the thing. As you can see the cable coming out of the box has already been sealed by using sealant glue (can use glue gun, or whatever is suitable).
