The new Streamlight TLR VIR Pistol-Mounted C4 LED Weapon Light is one to look at. With the integrated LED IR Emitter, and only 3.39" long, shining a bright 300 lumens, it's a force to be reckoned with.

This great weapon light is good in high temperatures, shock-mounted, impact resistant and made with a Boro Float Glass with anti-reflective coating. The one-handed snap-on and tighten interface keeps hands away from the muzzle when attaching/detaching. It fits securely onto many pistols with rails and all long guns with MIL-STD-1913 rails. Included in this are keys for glock-style, picatinny, Beretta 90two, S&W 99 and S&W TSW.
The body of this thing is indestructable,--made with a machined aircraft aluminum body with high impact, chemically resistant engineering polymer mode selection housing.
The tethered battery door and latch mechanism prevents battery door loss while providing easy battery replacement. The three-position mode selector makes it easy to distinguish each--IR illumination, Safe OFF, or Visible Illumination. It also has an steady on/off switch, and a double-tap feature of a momentary switch within 0.4 seconds to activate the strobe. If you don't want the strobe at all? No problem. Just disable it!
