Mounting a flashlight on a fire helmet takes five minutes and a hex key. Mounting it so it stays put through a ceiling pull, clears your face shield, and does not compromise the helmet takes a little more thought. There are four ways to do it: a brim clamp, a bracket, a strap, or a helmet-specific mount. Which one works depends on your helmet, your eye protection, and the light. This guide walks through each method with the hardware Fire Safety USA stocks and the checks to run before you go in service.
Key Takeaways
- Check your helmet manufacturer's accessory guidance first. A helmet light is not part of the certified helmet.
- Never drill, cut, or glue a structural fire helmet shell to attach a light.
- Brim clamps (Streamlight Vantage, Vantage II) tighten onto a full brim with a hex set screw or thumb screw.
- Brackets hold a removable light: the Vantage 180 X quick-release bracket and Streamlight's Helmet Mount for 3AA and 4AA ProPolymer lights.
- Straps and bands (Streamlight Helmet Band, FoxFury silicone straps) attach without hardware and fit most helmets.
- After mounting, test the face shield through its full range, don your SCBA mask, and run the switch with gloves on.
Before You Mount Anything
Start with the helmet, not the light.
Read the manufacturer's accessory guidance. Bullard points out that NFPA 1971 cautions departments that accessories are not part of the certified product and can be attached by means the manufacturer never engineered or authorized. MSA tells Cairns owners to use only flashlight brackets and accessories MSA supplies or approves. NFPA 1970 has since replaced NFPA 1971. Our NFPA 1970 vs. NFPA 1971 breakdown explains what changed for helmets.
Do not modify the shell. Drilling, cutting, or bonding anything to a structural helmet shell changes how it performs under impact and heat. Every method below clamps, clips, or straps on.
Know your eye protection. A 4-inch or 6-inch face shield, goggles, and Bourkes each sweep a different arc. The light has to stay out of that arc.
Know your brim. Traditional helmets have a long rear brim and a wide front brim. Modern helmets have a shorter, thicker brim. Some brim clamps only fit one well. Our Bullard fire helmet comparison shows how brims differ across the UST LowRider, LTX, USRX, PX, and FX.
Method 1: Brim Clamp
A brim clamp slides over the edge of the brim and tightens with a screw. It gives the most solid mount and the lowest profile. The Streamlight Vantage and Vantage II both use one.
Mounting a Streamlight Vantage II (Fire Model)
The Vantage II fire model clamps above or below the brim. From Streamlight's instructions:
- Choose the position above or below the brim.
- Loosen the clamp locking screw.
- Slide the clamp over the brim and rotate it to the position you want.
- Tighten the locking screw with the included hex key until the light is secure.
The swivel clamp lets you trim the beam angle after mounting. The battery loads from the front, so you can change it without removing the light.
Mounting a Streamlight Vantage
The current Streamlight Vantage uses two different fasteners depending on position:
- Above the brim: swap the installed set screw for the included thumb screw, slide the clamp on, rotate it into position, and tighten the thumb screw. Streamlight says a coin works and a screwdriver should not be used.
- Below the brim: loosen the set screw with the included hex wrench, slide the clamp on, rotate it into position, and tighten with the hex wrench.
- Leather helmets: place the included force spreader on the end of the screw to spread clamp pressure across the leather.
Mount the Vantage below the brim if you want to change batteries without removing it. Above the brim, Streamlight's instructions call for taking the light and force spreader off the helmet first.
Method 2: Bracket
A bracket stays on the helmet and the light clips in and out. Choose this method if the light also works as a handheld or coat light.
Streamlight Vantage 180 X Quick-Release Bracket
The Vantage 180 X ships with a helmet bracket and hex key. Streamlight says the bracket fits the brim or shell of many helmet styles:
- Pick the mounting location and orientation.
- Place the bracket opening on the brim.
- Tighten both mounting screws until the bracket is firm.
- Slide the light's clip into the open channel until it locks.
- Angle the light to put the beam where you need it.
- To remove it, press the lock bar and slide the light out.
Off the helmet, the same light clips to your coat as a right-angle light and switches its rear LED from blue to a white downcast flood.
Streamlight Helmet Mount for 3AA and 4AA Lights
Streamlight's aluminum Helmet Mount attaches to the helmet brim and holds Streamlight 3AA ProPolymer HAZ-LO and 4AA ProPolymer series flashlights. Use it when your department already issues those handhelds and wants them on the helmet for hands-free work.
FoxFury SideSlide Adapters
FoxFury's SideSlide lights lock into a helmet adapter and slide out for handheld use. The SideSlide C-Clamp adapter clamps to most U.S.-style fire helmets and full-brim safety helmets. The SideSlide Bolt adapter is built for select rescue and safety helmets. Confirm fit with your specific rescue helmet model before you buy the bolt version.
Method 3: Straps and Bands
Straps hold a light against the outside of the helmet without any screws. They fit almost any helmet and come off in seconds.
- Streamlight Helmet Band: a 1.75-inch elastic retention band that holds a flashlight or small tool against most fire helmets and hard hats. It is the simplest, lowest-cost way to put a light on a helmet. Our listing does not include a heat rating for the band, so confirm it fits your department's policy before using it on a structural helmet in interior operations.
- FoxFury silicone helmet straps: the Command LoPro and Command+ Tilt attach with a silicone strap that grips the shell. FoxFury states these lights meet NFPA fire-resistant requirements when used with the silicone strap, so do not swap in a generic elastic band on a structural helmet.
Route any strap so it sits on the shell, clear of the chin strap hardware, ear covers, and the ratchet.
Method 4: Helmet-Specific Mounts
Some helmets need a light built for them.
- MSA Cairns 1010 and 1044: the Vantage II MSA model (item 69337) mounts on top of the brim using the helmet's chin strap screws. Remove the screws, plate, and two nuts, set the adapter plate and wedge spacer with the arrow pointing forward and the thick end of the wedge toward the back, then slide on the clamp and retighten the chin strap screws. The wedge gives the beam a slight downward aim. Streamlight states this setup meets NFPA 1851 accessory guidance for those helmets.
- Gallet-style helmets: the Vantage II Gallet model clicks into the helmet's accessory slot.
- Industrial hard hats: the Vantage II industrial model (item 69333) slides into the hard hat's accessory slot.
Above or Below the Brim?
Both positions work. The deciding factors are:
- Battery access. Below the brim, the Vantage changes batteries without coming off. The Vantage II changes from the front in either position.
- Eye protection. A light above the brim can block a face shield as it pivots up. A light below the brim can block goggles or Bourkes as they drop. Test both.
- Exposure. A light under the brim sits in the brim's shadow and stays out of the way of overhead debris. A light on top is easier to reach and adjust.
Six Checks Before You Go In Service
- Tug test. Pull the light firmly in every direction. It should not rotate or shift on the brim.
- Eye protection sweep. Raise and lower the face shield or goggles through their full range. Nothing should touch the light.
- SCBA check. Don your mask and hood, then put the helmet on. Confirm the light does not change helmet fit or press on the mask. Our guide to fitting a fire helmet with an SCBA covers that sequence.
- Gloved switch test. Turn the light on and off, and change modes, with structural gloves on.
- Aim. Stand in a dark bay and check that the beam lands ahead on the floor, not on the ceiling.
- Inspection log. Add the light and its mount to your routine helmet inspection. Check screw tightness after every fire. Our article on fire helmet inspection, cleaning, and retirement lays out the schedule.
Common Mistakes
- Overtightening the clamp. Tighten until the light is firm, then stop. Overtightening can damage a composite brim edge or crush leather. Use the force spreader on leather.
- Swapping straps. FoxFury ties its NFPA fire-resistant claim to its own silicone strap. Replacing it with a generic elastic band gives up that claim.
- Skipping the mask check. A light that clears the shield with no SCBA can block it with the mask on.
- Mounting a light the helmet maker prohibits. If the manufacturer lists approved accessories, stay on that list. Our fire helmet accessories and replacement parts guide covers what to replace and when.
Frequently Asked Questions
How do you attach a flashlight to a fire helmet?
Use a brim clamp, a bracket, a strap, or a helmet-specific mount. Brim clamps such as the Streamlight Vantage tighten onto the brim with a screw. Brackets hold a removable light. Straps such as the Streamlight Helmet Band hold a light against the shell with no hardware.
Does mounting a light void my helmet's NFPA certification?
A light is an accessory, not part of the certified helmet. Follow your helmet manufacturer's guidance on approved accessories, and never drill or modify the shell. Some combinations, such as the Vantage II MSA model on Cairns 1010 and 1044 helmets, are documented by the light maker as meeting accessory guidance.
Should a helmet light go above or below the brim?
Either works. Below the brim lets you change Vantage batteries without removing the light. Above the brim is easier to reach. Test your face shield or goggles in both positions before you decide.
What tools do I need to mount a Streamlight Vantage?
The Vantage and Vantage II ship with a hex key for the brim clamp. The Vantage also includes a thumb screw for above-brim mounting that you can tighten with a coin.
Can I mount a flashlight on a leather fire helmet?
Yes. The Streamlight Vantage includes a force spreader that sits between the clamp screw and the leather to spread the load. A strap-on light is another option that puts no clamp pressure on the brim.
How do I mount a light on an MSA Cairns helmet?
Buy the Vantage II MSA model (item 69337). It mounts on top of the brim using the helmet's existing chin strap screws and a wedge spacer that angles the beam slightly down.
