Nice bright white light. Much lower amperage than the bulb it replaced.

Drop in replacement for the PAR 36. Defiantly a Taxi Light, the Fresnel lense disperses the light horizontally, which is what you’d expect. I’m sure this in conjunction with a good landing light will make you that much more visible in the pattern or busy airspace as it is quite bright at a wider angle.

Whelen Parmetheus LED Landing lights are outstanding. This is the second aircraft Ive owned and the first thing I did was replace the incandescent lights with the Whelen LEDs. They are much brighter, last forever, and have hardly ANY current draw so you can leave them on the entire flight.

Q: Since those lights are PMAed for my airframe, can I install them under the provisions for preventative maintenance myself without having my A&P filing a 337 or signing off on them?

You will need to contact your A&P or local FAA office to determine if a 337 is required. You may want to contact Whelen directly and speak with their tech support to see if they can help.
