The 5 Best Glock 19 Pistol Lights


share on

September 20, 2022

Glock is the most popular semi-auto pistol in the world, leading to countless law enforcement, military, and even special ops groups using them as duty weapons and trusting their lives to them. The Glock 19 is smaller and more versatile than the Glock 17. It is often the choice for users looking for a fast tactical weapon or self-defense tool. 

The Glock 19 can accept countless tactical add-ons to increase its accuracy and effectiveness in the field. One of those add-ons is the tactical light or pistol light. The pistol light can light up the target and surrounding area, as well as temporarily blind someone who may be preparing to fire at you.

With the popularity of the Glock 19 platform, however, there are countless options for pistol lights on the market now. While some of these options are solid tactical illumination products, a significant portion is also garbage. We’ve done the research and pulled together the best Glock 19 pistol lights so that you can find the one that fits your needs the best.

One of the best lights on our list, the Viridian C5L Universal is one of the latest offerings from the well-known tactical illumination brand Viridian. They are relatively new but are gaining a devoted following, and with lights like this, it’s no wonder. The Viridian C5L Universal not only has a 140 lumen white light for illumination and tactical use, but it also includes a green laser for targeting assistance. The Viridian C5L Universal also has a nearly-instant activation due to Enhanced Combat Readiness, which can activate the light or the laser when the gun is removed from the holster.

Key Features

  • Bright 140 lumen light with strobe

Streamlight is one of the most well-known and beloved names when it comes to weapon-mounted lights. Not only do they have a solid reputation for consistent quality, but they offer products for just about any gun you need them for, and the Glock 19 is no exception.

The Streamlight 69290 TLR-6 is a combination of tactical light and laser sight, packed into a compact and sleek barrel-mounted attachment. The 100-lumen white light will easily handle any illumination needs and will push that light out up to a 20-yard effective range. The Streamlight 69290 TLR-6 can be easily activated with the trigger fingertip, and it can be set to activate the light, the laser, or both. 

Key Features

  • Super-light Streamlight design

Pistol Green Laser and Light Combo

Pistol Green is a little-known name, but they have created an incredibly effective laser-light combo. The output of 500 lumens is several times more powerful than some other models in the same space, which can make it far more effective outside, but a liability indoors. The laser can be seen from 100 yards and can be easily adjusted to zero with the bore.

The design is solid, though not as smooth as Streamlight-style lights. Low profile allows easy carrying, even in concealed situations. One of the main draws of the Pistol Green Laser and Light Combo, other than the quality, is the price, which is far lower than most other options.

Key Features

  • 500-lumen output
  • Simple brightness adjustment
  • USB rechargeable

Crimson Trace LG-639G Lasergrips Flashlight

The Crimson Trace LG-639G is one of the most unique flashlight and laser combinations available today, and it comes with some incredible benefits. First, since the lights are not mounted on the end of the barrel as with all other lights, the balance of the weapon is not affected. This also means that it is much easier to activate the lights during use, since the user doesn’t have to reach all the way to the front of the gun. 

The placement also means you don’t have to worry about it interfering with holstering, even in the tightest situations. The laser comes sighted to 50 feet, and the light itself has a great battery life, being able to run for 4 hours continuously. There are versions of the light available with both a red and a green laser diode.

Key Features

  • Incredibly unique grip-mounted design
  • Will not affect holstering
  • Instinctive Activation feature eliminates manual activation

What Is A Glock 19 Pistol Light?

A Glock 19 pistol light is a weapon-mounted light that is used to add supplemental lighting at night. Not only does it allow the operator to more safely navigate and acquire their target in the dark, but it can be used offensively as a way to prevent others from seeing or firing at you with any accuracy. The lights are generally very small and are attached to the front of the gun beneath the barrel, eliminating the need for the operator to carry a wholly separate light source.

Do You Need A Light For Your Glock 19?

If there is ever the potential for you to need to operate your Glock 19 in the dark or a nighttime scenario, then you should have one on your gun. While you may not ever use it, if you use your Glock 19 for protection or home defense, you should be prepared to be able to operate safely and effectively in a dark environment. 

What To Look For In Your Next Glock 19 Pistol Light

When you’re looking for a new Glock 19 pistol light, there are several things you’ll want to consider before hitting the checkout button. You want to be sure the weight is acceptable, as well as the dimensions and shape if you plan to carry. The ease of use, including zeroing and battery changes should be taken into consideration, as well as the overall brightness. Finally, consider if it includes a laser, which can save you precious attachment real estate.


The weight is an important consideration before you buy any pistol light, not that you’ll be able to do much about it, but you’ll need to be ready for the degree to which it will affect your shooting. Most people will need significant practice after mounting a pistol light since it so greatly changes the balance and operation of the gun.

Dimensions & Design

The general size and shape of the light will be important if you plan to carry the gun or holster it. In this case, you’ll want something that has a rounded, smoothed design, and as low of a profile as possible to make unholstering easy. If you aren’t going to be carrying, the design and dimensions of your light will matter only as far as your preferences are concerned.

Ease Of Use

A primary concern before buying your Glock 19 pistol light should be how easy and convenient it is to use. In a situation where you’ll be using your gun in the dark, you are likely going to have ample adrenaline in your system, and operating small buttons or switches may be difficult. Some of the best lights will have the functionality to automatically activate when picked up or unholstered for use. If these measures aren’t available, be sure the light can be easily activated when needed.


Brightness for flashlights is measured in lumens, with more lumens equalling more light. More light isn’t always the goal, particularly if you anticipate using the gun in a dark, enclosed area like home during an invasion. Brighter lights are more suited to outdoor nighttime use, while indoor use should be limited to avoid temporary vision damage.

Laser Inclusion

If you’re shopping for a light, you may not necessarily be shopping for a laser, but getting one included in a combination light can save you some valuable attachment space on your Glock 19. In most cases, you only have the space under your barrel for one attachment, and being able to find a combo unit that fits your needs means you don’t have to choose between a light or a laser.


Before you choose a pistol light for your Glock 19, make sure you’re thinking about which one would be best suited to your needs. There are several factors that we discussed that should be instrumental in your eventual pistol light choice, and failing to consider them could mean you end up with a light that you don’t like or is not optimal for your situation. Keep our buyer’s guide handy, however, and you’ll be ready to make an informed decision.
