Thanks for your comments. The goodman handles have used stainless inserts in the handle with Stainless screws for about six months. With regular maintenance neither are a problem but the stainless insert is better and more user friendly. Water proof E/O cords are available and have been for years. They just cost a bit more. Again care with the light head will nearly eliminate this risk. This is a problem with a very low frequency even with aggressive use. As for the lights leaking at depth this is a confined situation with unsubstantiated relation between light and user error. All the lights are tested to this depth before leaving and we regularly test and use them at this depth and deeper. Captured o-rings are dangerous due to combustion from battery off gassing and are not recommended. Lastly, we are always looking at other actuation options but given the extreme reliability of simple switches, their tremendously low failure and ease of operation a move away is not easily justified.
