Hi all,
I'm in the process of making a power supply box for my pedal bike lights. The board currently works and everything is GREAT, but I'm not sure how to get the wires from inside the box to outside.
If I want to make it professional looking, I don't want to just feed wires through a hole then silicon the hole shut. Plus I want it to be removeable. My bike lights use these connectors.

Which is just a simple locking/waterproof barrel connector. It's "waterproofness" comes from the fact that they're REALLY hard to push together. I would LOVE to use these, so I wouldn't have to cut the connectors off of my lights, but I cannot find a panel mount one. One that I could mount to the side of my box.
Failing that, what other waterproof/female/panel mount power connector would you recommend?
