I purchased the Whelen tail light a few years ago and for some reason the NAV light quit working. I contacted Whelen Aerospace and they replaced it without question. I will never shop anywhere else for my aircraft lights.

Whelen strobe is round-shaped whereas factory one is oval. A&P had to use some sealant to complete install of tail strobe. Also, factory tail strobe has no wire for white light, only strobe light.

Now fitted to a PA30C, excellent. Did need to increase the size of the hole in the rudder cap with a deburr tool, quite easily done. Replaced the old Whelen A500 strobe/posn vertical mount 14v.

I like the tail light. I am upgrading my 1984 Starduster Too to LED Navigation/Position lights. As such I am working to use the existing installation mounts. This has proven difficult. After a few calls to both ACS and Whelen I found through a friend that ACS has a bracket I can modify to help retrofit to this light. I was frustrated that both companies could not find this bracket. Part Numbers: 11-06900 and 11-07000, see Accessories

Installed the Whelen - Orion 500 12 volt tail light/strobe on my Mooney M20C , was a major improvement over the original, and is really bright, Was very easy to install, Along with the Whelen -Orion 650 wingtip light/strobe and Whelen LED landing light my Mooney has a high visibility for other planes in the air. Money well spent for safety.

Pilotshop assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Is there any reason the Orion 500 series lights can not be mounted on top of the vertical stabilizer?

Per Whelen, the Orion 500 Series Lights are designed to be mounted on the tail area, vertical stabilizer / rudder etc facing aft. However, the mounting screw holes are at 12 oclock and 6 oclock, not 3 and 9, so a minor modification will be necessary.

Q: Is the OR5001V a direct replacement for the A500AHD1?

Yes, the Orion 500 series (11-11975) is a LED replacement for the strobe style (11-03717).

Q: What is the type and size of wire I should run from cockpit when installing this Whelen Orion 500 series lighting?

We recommend shielded wire, the size will depend on the voltage of your system and the length of the wire.

Q: Can these units be mounted horizontally in a wig tip location as well as vertically in the tail to replace 11-03717 style units?

No, these lights are intended for tail mounting only. For wingtip see the OR 650 series 11-11966.

Q: Do you need a special power supply for the strobe portion of the Whelen Orion 500 series to work?

No, a separate power supply is not necessary to run these LED lights.

Q: Does the Whelen Orion 500 series lighting ship with form 8130?

No, if does not come with an 8130, but you can request it at the time of order for an additional cost.

Q: Can we connect the Whelen Orion 500 nav light wire with the strobe wire or is a separate power source wire necessary?

It is recommended to run a separate power wire for each function. This allows the pilot to turn off the strobe function when it has the potential to interfere with ground operations and other pilots.

Q: Do I need to use shielded wire with the Orion 500 lighting?

No. Shielded wire is not necessary for the Orion product line. Unshielded is acceptable.

Q: Does this rear tail light have a strobe built into it as well as stay lighted consistantly?

It has a steady burn and flash(strobe.)


It will fit. It has the same footprint as a single bulb tail light.
