Whelen Orion 500 LED Tail Light Replacement Lens
Part Number: 68-3951061A31 | Model Number: 90667
Restore the clarity, weather sealing, and structural protection of your aircraft's tail light with this genuine Whelen Aerospace Technologies (WAT) outer replacement lens. Engineered explicitly as the official factory replacement for the Orion 500 Series LED Tail Position / Anti-Collision Light assemblies (Models OR5001V and OR5002V), this lens keeps your white navigation and strobe lighting sharply focused and fully visible to surrounding air traffic.
Because the tail assembly sits directly in line with engine exhaust, moisture, and high thermal gradients, original lenses eventually become hazy, pitted, or crazed. Replacing a weathered lens is a simple, cost-effective maintenance task that instantly reclaims maximum candela output from your built-in LED circuitry, ensuring absolute compliance with FAA TSO requirements.
Key Features & Benefits
Genuine WAT Component: Certified FAA TSO sub-component designed for a flawless, drop-in fit over Orion 500 series lightheads.
High-Impact Polycarbonate: Molded from premium, aviation-grade polycarbonate that stands up to impact from hangar rash, runway debris, and bird strikes.
Advanced Clear Hard-Coat: Chemically treated at the factory to resist yellowing from intense UV rays and scratching from high-velocity air and cleaning cycles.
Optically Pure Structure: Smooth, non-distortion profile allows both the 4 constant-on position LEDs and the 18 flashing anti-collision LEDs to emit maximum lumens unhindered.
Perfect Direct Replacement: Installs easily using your existing factory Lens Retainer (P/N: 19-151080-100).
