There appears to be a lot to like about this new weapons light system from Safariland: 65 lumen LED, inexpensive AAA batteries, built in belt clip.
It seems the light locks onto the rail through the action of flipping the light up to the side, unlock by flipping it back down. Although this seems to be a pretty simple on/off system I have to wonder if it will stay locked on when you need it to stay locked on or too easily unlocked from the rail through the thumb pressure on the switch and/or the recoil of the pistol and possibly the fingers/thumb bumping down the light in recoil. Will be interested to see real user experience with this system. Looks to be about $100 for the light and mount combo or a very reasonable $35ish for just the mount if you have you own approx 1" light you want to use. (I see LA Police Gear is stocking them)
