6 Best Weapon Lights for Glock 19
1. Streamlight 76800 Stinger Switchblade 800-Lumen
The Streamlight 76800 Stinger Switchblade stands out as a highly versatile lighting solution that complements a Glock 19 setup, especially for users who value adaptability beyond a traditional rail-mounted weapon light.
Rather than focusing solely on momentary target illumination, this light excels as a multi-purpose tactical and inspection tool, making it an excellent companion for home defence, range work, and maintenance tasks where flexible lighting is critical.
One of the most impressive aspects of the Stinger Switchblade is its “five lights in one” design. It combines a wide area light, Colour-Rite warm white, cool white, UV light, and a bright white work light into a single compact unit.
This versatility allows shooters and professionals to transition seamlessly from general area illumination to detailed inspection work, such as checking gear, verifying markings, or identifying fluids and materials under UV light. For Glock 19 owners who want more than just a beam pointed downrange, this functionality adds serious value.
The inclusion of Colour-Rite Technology further elevates its performance. With a 90 CRI and 4000K warm white LED, the Switchblade delivers accurate colour rendering that reduces eye strain and prevents colour distortion.
This is especially useful during low-light inspections, firearm maintenance, or evidence identification, where true colour representation matters. The additional cool white and UV modes expand its usefulness well beyond standard tactical lighting.
Hands-free usability is another area where the Stinger Switchblade shines. Streamlight equipped this light with a tail-end magnet, stowable hang hook, self-standing base, and lip hook, offering multiple ways to position the light without holding it.
Despite its robust feature set, the Switchblade maintains a compact, slim profile that fits easily into toolboxes, range bags, or duty kits.
Its rechargeable lithium-ion battery provides extended runtime and eliminates the recurring cost of disposable batteries, making it both convenient and economical for frequent use.
As expected from Streamlight, durability is a major strength. The light is built from high-impact, super-tough nylon polymer, enhanced with Streamlight’s rocky stipple texture for a secure grip even in wet or gloved conditions.
