Very nice replacement for my Whelen A555A 28V Tail Light ... The pseudo strobe effect is impressive.

Good product, easy install on my Mooney .... basically a plug and play after removing strobe power box. Brighter then original that came with plane.

I installed this on my '59 Cessna over a year ago. I love it. No RFI at all. Increased visibility. Increased safety. Reduced current draw. People say that they can really see me at night with this product. It might not be PMA'd but neither is the fuse in the circuit. It is made to MIL spec's. An excellent product. I love it.

This is an excellent replacement for original tail light. It’s highly visible day or night. But be prepared to replace it after about 500 hours.

Not worth $10. Barely lights up. Poor quality. You can stare right at it, its so low powered.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce 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: This combination tail / beacon light states that it will fit where a standard Grimes light would go. Does it need separate wiring for the strobe and nav or is it a selectable function?

Per supplier: The unit mounts in the same mounting holes as the Grimes. We do provide new screws as most often the old one are usually rusty. The unit does not require additional wiring (use the existing wiring) for the grimes. The unit is self contained and all the electronics are in the lamp. The nine LEDs facing to the rear are on continuously while the 36 LEDs around the circumference flash. One circuit controls both functions on one circuit. On or off.

Q: I note on the PSA enterprises Combination tail beacon light it says not PMA'd. Does this mean its for experimental aircraft only?

That is correct, since this is not a PMA'd or TSO'd product, this is for use in experimental aircraft and not certified aircraft.

Q: My Grimes does not rotate anymore due to stripped gears. Can I remove the shield behind the bulb and use this light in a stationary position?

The manufacturer does not recommend modifying the product.

Q: What is the difference between this unit and the PSA #11-12040 (LED tail/beacon light). I have a standard Grimes mounted tail light, do I need this unit or will the drop in bulb (#11-12040) do the same thing? Is this unit and just the drop in bulb rated at the same brightness? Thanks AS, great service as always!

Part # 11-12042 is the full assembly. If you already have the Grimes then the bulb part # 11-12040 will be sufficient for the install.

Q: What is the rated output (lumens or candlepower) of the beacon and the tail light of this PSA combo light?

Per the manufacturer: This is rated at 20 candlepower of the tail light, and the beacon portion is about 100 candlepower.

Q: On my Mooney I have a Whelen power supply, which gives me the beacon flash. Do I need to remove it for this unit?

Yes you would need to remove it, LED lights do not require the power supply.
