Compliance and Applications

FAA AC 15/5345-44 (Current Edition)
FAA Engineering Brief No. 67

Illuminated Distance Remaining Markers indicate the distance to the end of the active runway to the pilot.

Arresting Gear Markers (or Moon Board) is primarily used by the military and is used to indicate the location of the aircraft arresting cable on the runway.

Our I-Lux signs solidly and seamlessly integrate off-the-shelf parts and custom fabrication for strength and flexibility while minimizing operating costs.


• Solid, seamless construction for strength and reliable performance.
• Lowest VA loads: Most efficient ETL Certified L-858 signs available.
• Quick, simple and less expensive to install.
• Bright, clear panels are highly impact resistant.
• Uses off-the-shelf MR16 lamps (lamp life ±10,000 hours) with no tools required for re-lamping.
• Style U passive, non-inductive control provides near-unity power factors on all regulator steps.

The platform for the I-Lux is a cabinet machined from solid, heavy gauge aluminum extrusion. Monolithic tops and bottoms are impervious to blowing rains, dirt, and snow because they are free of the gaps found in signs of modular construction.

The seamless panels of the I-Lux display messages without distortion. Bright and clear, I-Lux panels are up to 30 times more impact resistant than other brands.

Bringing light to the I-Lux are commercial off-the-shelf MR16 lamps. Changing the lamp is easy with no tools required - the cabinet stays closed up tight. Lamp life is approximately 10,000 hours - that makes over 2 years at 12 hours a day - so they won't be replaced often.

There are no expensive proprietary lamp replacements, when new lamps are needed, replacements are as close as the nearest hardware store.

The base model brightness controls use technology that has been proven for years in the field. Better, the I-Lux also features a Style U power control system - a passive non-inductive design that exhibits unity power factors on all regulator steps.

Tried and true, the I-Lux is the solid and sensible choice for hassle-free longevity.

Isolating Safety Switch

AGM Isolating Safety Switch

The AGM isolating safety switch allows the guidance sign power control and circuitry to be isolated from the airfield CCR circuit, providing a greater measure of safety when performing maintenance. This allows the rest of the airfield circuitry to remain illuminated to maintain necessary communication to pilots. The isolating safety switch is weatherproof with an IP67 rating and is also available with a weatherproof cover that provides additional protection against mechanical damage.

The switch is a DPDT (double pole double throw) style switch. Two terminals are for power to the PCM, two terminals are power from the isolation transformer, and two are the short circuit path.

Available with weatherproof toggle cover [part # C7-WPC]
