I feel like WML can be a narrow use items in certain circumstances. I am not really against WML but I will say that I am a proponent of having a hand held held light at all times. Using the WML within a home defense context would probably mitigate many of the misgivings that I have about a WML system in general. Personally, I use WML on long guns but not handguns. I am currently use Olight and have had very good results with them.
