LED Tail/Beacon Replacement Lamp Only 12Vw

read earlier reviews and time will tell. but initially works as advertised. nice and bright and flash portion of bulb works which you can see almost 180 degrees, depending on the mount. my piper lance because the frame around the outside glass cover blocks a little, but more like 160 degrees. for the price nothing else comes close and comparing the position lite to the bottom original no comparison.

Im going on 3 months with this light and its still working great! I really like that it flashes while staying constantly on in the rear, adds a level of safety that no other product has. Some people complain about the flashing part being too far back int he socket to be visible, but at night its very visible. Cheap way to add safety. If this does burn out soon, Ill replace it with another.

looks to be more robust than the original, which is great. only 4 stars because the price is too high.... there is no reason that in this day and age a replacement LED should cost $80,..... ok old guy rant over

Metal top of lamp separated from metal bottom. Was a great lamp until it separated. Had to order another. Not warranted after more than 30 days.

When they say you gain a beacon its because the unit flashes on/off. Had I known this I would not have bought.

Q: How is the beacon feature of this LED tail / beacon replacement lamp activated? Does it come on with the position light or is another wire required to operate the beacon? Part # 11-12040

Per the supplier: The beacon feature of our P936-45-12VW lamp is automatically activated when the lamp comes on. You do not need another wire.

Q: Regarding Part Number 11-12040: What is the wattage on this lamp?

Per the supplier: 12 volt x Less than .2 amps = 2 watts

Q: One 12v power wire only, nothing else required to make this flash on/off? Id like to install on my 172 vertical fin and want to know if I must remove my tail bulkhead mounted beacon flasher.

Per supplier: P/N# 11-12040, is a replacement lamp only. No wire involved.

Q: Will this replace incandescent bulb 040-0028 for my 172 anti collision beacon?

Per the manufacturer: No, this bulb is made to fit the tail light in the tail cone. To replace the beacon on top of the tail you must use part number 11-07243.

Q: I have a Cessna 182 RG that takes bulb number LAMP MS35478-307. Is this a direct replacement for the anti collision tail cone lamp. And is this FAA approved for my 182?

Part number 11-12040 is not approved for certified aircraft as of 3/9/15. This part will not fit as a direct replacement for your 182, a new socket must be installed first.

Q: I own a 1959 Bell 47 G2... One of my original Grimes manufactured position lights is burnt out. Can I purchase one of these bulbs to replace the one on the helicopter?

No, the PSA tail light will not work as a position light. This light is designed to fit in the standard tail light assembly.

Q: Is this a FAA TSO Approved drop in replacement for an incandescent tail nav light in a certified aircraft? My light is always on.

No, this unit is not FAA Approved and is intended for use in experimental aircraft only.

Q: Is this lamp red?

This is a white light. The beacon could have a red lens on it though.

Q: Will this replace GE-1073?

Yes, it will.
