Clear vision is essential in any survival situation, since it allows you to observe, orient, decide, and then act on what's around you. In the dark of night or a pitch-black room, it can be difficult to accomplish any of those tasks reliably, so illumination is key.
However, there's one particular time when visibility is almost guaranteed to make the difference between life and death: self-defense with a firearm. If you can't see your attacker clearly, you may hesitate to fire or miss your target completely; and with devastating consequences. Worse, misidentification of an innocent as a threat may lead to a different set of devastating consequences.
Therefore, we expanded our HighLights guide for this important theme, selecting 10 pistol flashlights to test and review. These lights offer diverse sizes, features, controls, and prices, so you should be able to find one that fits your specific needs. For evaluation purposes, we selected lights that fit the most popular pistol on the market, the Glock 19. If you own or carry a different gun, that's not a problem — many of these weapon-mounted lights (WMLs) are universal-fit, and the remaining few offer similar variants that fit other guns. Keep in mind, holster selection can be limited for light-bearing pistols, but it's a secondary concern for bedside guns.
Most importantly, each of these lights can help you identify a threat in the shadows and decide if you need to pull the trigger. No other type of flashlight carries such a heavy burden.
