When and Why Should You Use a Night Light on a Glock and What Are the Benefits?

Why Should You Add a Light to a Glock?

As we mentioned at the beginning of this article, a weapon light is a great idea for identifying your target.

But that’s not the only benefit of adding a tactical light to your Glock.

It also keeps one hand free. If you have a flashlight in one hand and gun in another, what do you do when you have to open a door?

Sure, you can probably grab the handle with the hand holding the flashlight, but that’s awkward and points the light in an odd direction. If you slip, you can potentially shine the light in your eyes and blind yourself.

Which brings us to the second advantage of a tactical light: they are bright enough to blind whoever is on the receiving end of the light.

If that’s a criminal, you just put yourself at a big advantage!

Buying a quality weapon light instead of a cheap generic light is a good idea because quality lights are reliable. You do not want the light to die at the worst time.


When Should You Add a Light to a Glock?

Any weapon that’s used for home defense should have a flashlight on it.

Most home invasions happen at night, so the advantage will go to the person who sees the other one first. If you have to turn on light switches as you go, that potential home invader will see you first.


How to Choose the Best Glock Light

Though this list of the best Glock lights should help make it easier to choose a flashlight for your Glock, you should still know what to look for in a weapon light.

Not all Glock tactical lights are made the same, so here are four factors you should keep in mind as you shop around.

The first, and biggest, factor is whether or not the weapon light will even fit your Glock. If it doesn’t fit your model of handgun, why would you throw your money away?

Most of the lights on this list are cross-compatible. The Streamlight TLR-1 HL will fit a Glock 17, and the SureFire X300U-A Ultra will fit a Glock 19.

However, if you have a subcompact Glock, then your choices are much more limited. A light for the Glock 26 will not fit the Glock 43, for example.

Make sure your specific model is mentioned and you are good to go!

Most of the time, brighter is better. A brighter light illuminates more and blinds potential opponents better.

However, this is not always the case. In a small house with bright walls, 800 lumens may be enough to blind yourself even if you aim the light at a wall!

The longer the light can stay on, the better. This saves money on batteries and can keep the light from dying when you need it to stay on.



With weapon lights, you get what you pay for. More expensive flashlights are often more rugged. Pick your budget and don’t cheap out on a light.


Top Brands

Four main brands dominate the tactical flashlight market. Chances are, if you want a quality Glock light, you will buy from one of the following four brands.


Crimson Trace

Crimson Trace became known for their tactical laser sights designed for people who carry concealed firearms. Rather than mount the laser to the front of the gun, Crimson Trace lasers are integrated into the grip or trigger guard. This makes the laser sight less bulky and more natural to use.

Their flashlight models are similar, though the light bulbs are larger than laser diodes so they can’t hide the lights in the grip. They are still a great brand for ease-of-use, because their lights are made with the same philosophy of not needing to go out of your way to use them. Grip the gun and you are ready to go!

The disadvantage of Crimson Trace is how they rapidly develop and discontinue models. This can make it difficult to keep track of which model is the current version.

Also, they do not like to share certain dimensions of their products online.

Finally, the body of Crimson Trace lights and lasers are primarily made from polymer instead of metal. This keeps the weight down but makes them less rugged than similar products by other brands.



Streamlight logo

If you gather a large number of gun owners in a room and look at the lights on their guns, most of them will have a Streamlight of one type or another.

Streamlight is the current champion of weapon-mounted flashlights. They are used by hunters, fishermen, law enforcement officials, and private security professionals. Streamlight also prizes customer feedback and actively seeks out information on their products by the people who use them.

Not everyone who uses Streamlight flashlights does so with a gun. Streamlight also supplies lights to construction crews, miners, and firefighters. People all over the world who depend on their light to keep them safe at work choose Streamlight.

This feedback and experience with working in tough conditions means that Streamlight’s tactical lights are rugged and dependable. They can withstand impacts and are resistant to water.

If something goes wrong with a Streamlight light that wasn’t due to abuse or normal wear, Streamlight will make it right. They have a lifetime warranty on most flashlight components and a 2-year warranty on the electronics.



SureFire logo

Streamlight may put out rugged products, but they still are not as tough as anything produced by SureFire.

SureFire has contracts with the U.S. Armed Forces. They also sell flashlights and lasers to many law enforcement agencies.

SureFire has long been involved in developing weapon illumination.

In fact, SureFire invented the first laser sight, a telescope-sized device that mounted to the .357 Magnum Colt Trooper. That was back when they were called Laser Products Corporation. Eventually, their flashlights overshadowed their laser sights, and they changed their name to SureFire.

Today’s SureFire products are much more efficient than the monstrosity that was the first laser sight, but they are no less rugged.

Many SureFire lights are waterproof, not just water resistant. They also sport advanced electronics that modulate the beam intensity so the LED bulb does not overheat and burn itself out.

The only problem with SureFire is that they are so well made and so advanced that they are often the most expensive choice. For professionals, this is a no-brainer.

But if you have a limited budget, you do not always need the pay the expense for that much ruggedness. If your gun lives in your nightstand, why spend the money for a light that can survive the battlefield?



Viridian logoViridian, full name Viridian Weapon Technologies, is not as prestigious as Streamlight or SureFire, but this does not make them any worse as a company. They are merely newer and have not yet built up their reputation to the same level as other tactical flashlight companies.

In addition to weapon-mounted lights and lasers, Viridian Weapon Technologies also has weapon-mounted cameras for law enforcement purposes. These cameras are less expensive than body cameras and are less liable to be blocked when the gun is being used.

You can even buy the XTL Gen 3, a tactical light and HD camera that attaches to the front of your full-sized Glock. It may be expensive, but video evidence may be able to save you in a defensive-shooting court case.

For many people, though, the main draw of a Viridian flashlight is the Instant-On Enhanced Combat Readiness technology. Fingers can fumble when searching for the light switch, whereas ECR turns the light on as you draw from the holster, making the light much more simple and easy to use.

This can shave off precious seconds when seconds matter most.



  • How do I mount a light to my Glock 19?

Thankfully, most Glocks have a built-in accessory rail. This makes mounting the light easy.

All you have to do is loosen the flashlight’s bolt, slide the light over the rail, and tighten the bolt again.

Some flashlights replace the Glock’s guide rod. This decreases the bulk on the gun but is much harder to install if you are not comfortable completely tearing apart your pistol. Please pay attention to the provided instructions or use the services of a gunsmith.

Make sure that your glock 19 holster will fit the light too!


  • How do I install batteries in my Glock light?

Replacing the batteries on those fiddly little weapon lights can be difficult! The Streamlight TLR-1 is notorious for frustrating new owners.

To open the battery compartment of the Streamlight TLR-1, it needs to be removed from the Glock. Find the tab on top of the light (where the light mounts to the Picatinny rail) and flip it up. Then pull it toward the front of the light.

This partially opens the battery compartment. You need to then grab the bottom of the rear hatch and lift it toward the top of the light to disengage the part that’s still holding on.

Insert the batteries then reassemble the flashlight by reversing the order. Hook the bottom of the hatch into a lip on the bottom of the TLR-1, then pull the top tab toward that hatch.


  • How do I remove light scratches from the Glock’s slide?

Weapon lights are often metal and can scratch the Glock’s slide during installation. Whoops! It’s happened to the best of us.

Chances are the slide itself is not actually scratched because Glocks have an extremely hard Tenifer or Melonite finish that penetrates the metal. What looks like scratches is often the softer metal from the flashlight’s body.

In this case, a little steel wool will rub it out.

Some Glocks, though, have an additional finish applied over the Tenifer/Melonite. This can be blueing or parkerization.

To fix those scratches, you will need to use a touch-up pen by Birchwood Casey.
