The gear you use, just like you, has a lineage and ancestors. Take a short walk through history and learn about Weapon Mounted Lights. 

Nothing from a vacuum - a brief history of weapon-mounted lights.

“It is better to light a candle than curse the darkness.” -Eleanor Roosevelt

The Weapon Mounted Light (WML) that currently rides on the rifles and pistols of fighting men of all types and stripes wasn’t invented in a vacuum, and it’s certainly not new. Like, really not new. To get that half thousand+ of reliable lumens in a small durable package took a long time and a colluding set of circumstances.

What was the first weapon mounted light? Though surely humans have been hacking each other apart by firelight and slashing with swords by torchlight since those implements were invented, we can’t really classify a campfire as a “weapon mounted light.” While a 17th-century matchlock would provide an ember of illumination, it was for the operation of the musket itself and insufficient for anything other than that.

If you’re on social media, you may have seen this picture show up recently.

The History of WML (s) - Weapon Mounted Lights

This is a Rarissima pistola a pietra focaia per la caccia notturna, which at least per Google translator means “Rare flintlock pistol for night hunting”. It’s currently on auction at Czernys.

The pistol is estimated to be from around 1800. It’s worth noting that there’s a rudimentary lens to focus the candlelight and that the entire shebang is integral to the flintlock. It’s fun to imagine the Mark Warrens and Will Pettys of the day arguing to only use candle wax derived from Sperm whales rather than beeswax because of its brighter light.

While it was probably okay for that special purpose (lonely night hunters), it didn’t catch on. For one, it’s rather heavy and ungainly. No doubt it got hot very quickly, couldn’t be easily concealed, and when you took the time to light it, it probably stayed on for a long time. I bet reloading could get exciting too. Having one man with a lantern and another with a weapon was simply more efficient. This was developed for a special purpose. Thus, we look at this with curiosity.

But how about light bulbs?

The incandescent light bulb was invented by Thomas Edison (or, just as likely, stolen by Edison) back in 1879. The first portable battery was invented in 1888. Put the two together and you have the flashlight, 1898.

And just fourteen years later, US Patent 1070883 was issued for a Weapon Mounted Light. More than that, it was integral to the pistol, adjustable, and activated by a pressure pad built into the grip. Per the patent, the light was designed to illuminate the target but not the shooter.

Here’s an excerpt from the patent:

Heretofore in the operation of firearms in a dark room or after night where there is no illumination, difficulty has been experienced in properly locating the object or target to be shot at, and any illuminant carried by the marksman results in danger to the latter.

This invention overcomes the above difliculties by providing an intermittent illumination of small character and of great density which does not illuminate the marksman, but the target exclusively, especially adaptable to protecting one from the assaults of burglars, who more commonly operate in a darkened locality.

Older style English aside, does it sound familiar?

Fred Forrester was a man well ahead of his time. I do not know if any were actually produced nor if any survive today.

But no, this didn’t catch on it. Back in the early 2000’s, the issued Visible Light Illuminator (VLI) was temperamental. I can only imagine this was far worse, both in regards to durability and light output.

The ability to fight in darkness has always been a great advantage–just not one that’s come easily. Though there have been some large battles waged in the dark of night throughout history, they’re always highlighted as the exception rather than the rule. During the Great War many advances in night fighting were made; illumination shells  provided the backdrop and tracer rounds tracked the efficacy. This continued into WWII. The Japanese in particular were said to be excellent night fighters, and part of the reason they dominated the Pacific for much of the war. The naval and aviation services also increased capabilities on all fronts.

Reeder pointed out some light use by the Finns that is at least somewhat reminiscent of poaching (he too reads the occasional esoteric libram for fun and entertainment). In  December 1939 the Finnish Army was conducting a planned retreat in the face of far more Soviet troops. At one point during the night of December 10, HQ  troops under Col. Aaro Pajari of the Finnish 6th Division were flanked by a Russian battalion and nearly routed. Part of their remarkable stand, however, was a “hunter-killer team” of two of Pajari’s men. One carried a powerful flashlight, the other a Suomi submachine gun. Together they prowled the woods and when they spotted Russian soldiers one would switch the light on, at which point the Russians “…invariably froze like deer, just for an instant.” In that instant one Sgt. Miinalainen would cut them down with his SMG. Not a weapon mounted light, but the principle was there. Hakkaa päälle!

Both the Allies and Axis powers worked on night vision. The early models look big and ridiculous by modern standards, but in the land of the blind, the one eyed man is king.

During the intervening years between the wars, there were some advancements. JW Reid, a Special Agent for Union Pacific, used this guy to hunt down burglars:

J. Zajac patented a “firearm light” which used dual beams (on either side of the barrel) that would converge 100 yards away.

We did see urban fighting in WWII and beyond. This is the area, at least for military personnel, where white lights tend to dominate in modern times. As to why they weren’t used in WWII, I have a theory. The TL-122 flashlight was issued. You know, that ugly angle head dinosaur. Big, dumb, and no doubt a similar bulb would have broken under the recoil of the Garand. Furthermore, in those days of mass air raids and carpet bombing, civilian casualties were not as much a consideration as they are today.

We would see a limited-run military WML soon though. Like its predecessors used for law enforcement and hunting, it would serve a special purpose.

In 1962 the Limited War Laboratory (LWL) was created by the US Army. Their mission was to make all manner of cool shit to counter the impending Soviet threat. They made the great grandparents of many things we use today, like silent sniper rifles (with 500 grains of ‘fuck you’ per projectile), illuminated reticle scopes, backpack feeding systems for the M60, and even plastic M16 magazines–any of this ringing a bell?. They also worked on solutions for the “tunnel problem” in Vietnam.

The Tunnel Rat kit was produced in 1966. Among things like a specialized suppressed .38 revolver, a bone conducting microphone that attached to the skull, and a headlamp that activated via a bite switch (think CamelBak nozzle), there was a weapon light. The kit was not adopted due to numerous issues (read the full write up here), but it was a step in the right direction.

A couple years ago Larry Vickers recreated and then gave details about the weapon he used during the Model Prison Raid during the invasion of Panama. The same configuration was later used for SCUD hunting during Operation Desert Storm.

…a waterproof SCUBA dive flashlight painted black was installed underneath the bottom handguard via hose clamps, and then our commo guys wired the flashlight for push button activation. It worked well for the intended purposes but they were replaced in short order once Surefire 6P flashlights came online. 1988 was a long time before Surefire weapon lights hit the market and became the industry standard.”

It’s not strictly true that Surefire wasn’t around. At the time they were named Laser Products, and as you’ve already guessed, they focused on lasers.

Surefire made their fist official foray into lights in 1985 with the Model 310. It was for the 1911, and though it looks silly now, it stuck around in one way or another for quite some time. Later WML models didn’t look quite so clumsy but are easily recognized as dated.

So, what happened? How did this previously special-purpose item, once nearly solely relegated to Special Forces and SWAT/ERT/ESU/whatever, make it to general use? Houses. Caves. Civilian casualties. Fratricide. Places where night vision of the day couldn’t exclusively be used, and not everyone had it anyway. During the early years in Iraq, the very best we could get our hands on were 120-lumen incandescent SureFires if you were lucky. They ran for twenty minutes on (2) CR-123 batteries. And we loved them for it.  Because during the invasion we had the relatively fragile, low powered, and leaky VLI or worse.

Nothing brings faster advancements in warfare than warfare itself.

Our current crop of bright, durable, and long-running WMLs wouldn’t exist without previous development, needs, and failures. We needed the bulbs, batteries, electronics, and mission requirements first.

No doubt our children will look at X400U’s and panoramic GPNVG’s the same way we look at that laser on the AMT Longslide from Terminator or a Korean War NVG setup.

    Note: You can start even earlier than that the 18th century. The 16th century saw smaller shields equipped with lamps.
