Product Description
The TriLite FFLP flashing warning light is a compact beacon for industrial signaling, safety and warning work, indoors or out. TriLite's current product page covers the AC model, the FFLP-110P: permanent mount, 25 watt incandescent lamp, 115 VAC nominal, flashing 80 to 90 times a minute.
TriLite installation literature also documents DC versions of the FFLP with 12V, 24V, 36V and 48V replacement lamps, along with magnetic installation. Distributor listings carry DC color and voltage combinations too. Documented is not the same as stocked, so confirm the configuration before you order a fleet's worth.
Every dome color runs on the same body: amber, blue, clear and red. The lens is a 360 degree Fresnel, so the flash reads from any angle around the machine.
What is the TriLite FFLP flashing warning light?
The FFLP is a compact incandescent flashing warning light for indoor and outdoor signaling. TriLite lists solid-state construction, a 360 degree Fresnel lens and a durable ABS base. The current AC model draws 0.21 amps at 115 VAC and flashes 80 to 90 times a minute. There is no sweep and no rotating mirror. The lamp switches on and off at a fixed rate, which keeps the mechanism simple and the maintenance list short.
FFLP AC or FFLP DC: which one do you need?
Go AC if the light mounts to a fixed structure with mains power nearby: a wall, a column, a machine guard, a door frame. The FFLP-110P is the current AC model at 115 VAC nominal. Go DC if the light rides on a vehicle and draws from its battery. TriLite documents DC FFLP models at 12V, 24V, 36V and 48V. One caution worth repeating: TriLite's live product page is AC-focused, so treat DC availability as something to confirm rather than assume.
Which FFLP voltage should you order?
Match the voltage to the supply you are wiring into. A fixed installation on building power takes the 115 VAC model. A vehicle installation takes the DC voltage on the battery plate: 12V for pickups and smaller lift trucks, 24V, 36V or 48V for larger electric forklifts and tugs. Replacement lamps are voltage specific as well, so note the voltage when you stock spares.
Permanent mount or magnetic mount?
Permanent is the confirmed current configuration. The FFLP-110P fixes in place and wires into the supply, which suits a light that never moves. TriLite installation documentation also covers magnetic models, which sit on flat steel and power through a DC plug. Magnetic wins when one light covers several machines or a temporary job. The catch is the exposed cord and the need for a clean steel surface to hold on.
What dome colors does the FFLP come in?
Amber, blue, clear and red. Amber is the default for general equipment and traffic warning. Red and blue tend to mark specific zones or conditions inside a building. Clear gives the highest raw output because nothing filters the lamp. Color conventions vary by site and by jurisdiction, so check your own policy before standardizing.
Can you use the FFLP on forklifts and industrial vehicles?
Distributor listings position the DC FFLP variants for industrial use including lift trucks and shop vehicles. The AC model suits fixed points instead: dock doors, conveyor guards, machine cells, gate approaches and anywhere foot traffic crosses equipment. Set the mounting height so the flash clears racking and shows before the hazard reaches the person you are warning.
Flashing, rotating or strobe: what is the difference?
A flashing light switches its output on and off at a steady rate. A rotating beacon spins a reflector to sweep a beam. A strobe fires a short, very bright burst. Flashing units like the FFLP and the FF3 keep the mechanism simple. Rotating beacons such as the MR3 give a moving beam that reads well in open areas. Strobes like the MS1 and MS11 punch through bright ambient light. Match the type to the site rather than defaulting to one.

Customer Testimonials
Life-changing for my daughter with asthma. We installed these in her bedroom and playroom, and her nighttime coughing has decreased dramatically. The pediatrician even noticed improvement in her breathing. We now replace filters monthly religiously – it is the best $20/month we spend for her health.
– Jennifer M., Portland, OR (Mother of 8-year-old with asthma)
I cannot believe the difference in dust accumulation. We used to dust furniture near vents twice a week – now maybe once a month. And my seasonal allergies are noticeably better when I am at home. The filter replacement is super easy, takes 30 seconds. Wish I had found these years ago.
– Robert T., Atlanta, GA (Allergy sufferer)
We have two cats and my husband is allergic. These filters in the bedroom have been a marriage-saver! He can actually breathe at night now. We still have the cats (obviously), but the constant sneezing and congestion is gone. The filters definitely catch pet hair – you can see it when you replace them monthly.
– Sandra K., Chicago, IL (Pet owner)
As a property manager, tenants with allergies always complained about air quality. These covers have been perfect – affordable enough to install in multiple units, and the health benefit keeps tenants happy and renewing leases. I stock replacement filters and sell them at cost. Total game-changer for tenant satisfaction.
– Patricia L., Denver, CO (Property Manager, 40 units)
My son has severe dust mite allergies. His allergist recommended covering vents in his bedroom. These filter covers have made such a difference – his morning congestion is almost gone. The investment in monthly filters is nothing compared to what we used to spend on allergy medications.
