It appears as though I can use these on a Cessna 172, and that it is a simple replacement of bulb & lens operation - a 1 cuppa coffee job. Is that correct? And, what kind of paperwork is required for approval?
Per the supplier: This Sextant product will work just fine on your 172. You simply operate your nav switch each time you want to change modes. No switches, wires, or boxes necessary...it is really plug and play. With each kit comes a certificate that the product meets FAA 20-74.
A follow-up to the C172 question, YES it was really that easy to install. I took the extra time to clean the sockets of any corrosion with steel wool and spray contact cleaner prior to installation. I also used the supplied dielectric grease to waterproof the connection during installation, just about guaranteeing I'll never have to open the NAV light fixtures again. Total time for installation was barely more than 1-hour for all three lamps. The end result was WELL worth the money and the effort!
Thank you for following up with this information.
Do these satisfy the anti-collision beacon requirement for night VFR?
Per the supplier: My strobe lights do not meet the requirements for anti-collision lights. They are only a replacement for the standard navigation or position lights, with the additional strobe feature for safety.
Is there a right and a wrong way to install these NavStrobe lights?
Per our tech: You just need to make sure you put the correct color lamp on the correct side wing tip. Green goes on the right (co-pilot side) and the red goes on the left (pilot side) wing tip. Replace the colored wing tip lenses with the clear ones in the kit. The tail uses the existing lens, just replace the old lamp with the new LED lamp in the kit.
I have a combination strobe and halogen tail light, Whelen A500A. Will the white LED lamp in your kit fit into that receptacle? I want to retain the tail strobe and add your flashing tail lamp.
Per the supplier: According to the Whelen website their A500A light is a direct replacement for the original GE-94 incandescent light. Since all of my tailfin lights also replace the GE-94, then I can assume will work as a replacement bulb.
Are these kits universal? I fly a 1970 Mooney M20F. Will they work with my existing lights? The parts manual shows my lights as:
Grimes- A1285-R-12, A1285-G-12, A2064-1777
Yes, they will replace most bulbs found in common strobe systems. For your particular system, these should work just fine as replacements.
How do I know if these will worth on my airplane? I have a 1976 Cessna 150M.
We recommend that you check the currently installed bulb on your aircraft. We have added some application info to the "Overview" tab on the web page. These NavStrobe bulbs will replace most common bulbs found in GA aircraft. Please check the applicable bulb numbers listed on this web page against the currently installed bulbs on your aircraft. You can find the bulb number for your aircraft by looking in your parts manual or physically pulling one off the plane. If you don't see a matching number to what we have referenced, you can check the dimensions for the BAY15S (wing tip) and BA15S (tail) base styles in the "Dimensional Drawing" tab. Then you can measure your current bulbs to see if they will fit. Like we noted on the web page, these are nearly universal replacement bulbs for GA aircraft. This Sextant 30W kit will replace about 99% of all GA position lights. These should be no problem in your Cessna 150.
I have tried other LED bulbs for my Cherokee and found that they cause so much static my radios are unusable. Do your bulbs have circuitry to eliminate static?
Per the manufacturer: I have designed my Sextant products to have a very low RFI emission. There is a small amount of RFI coming from my bulbs in the strobe mode. It is well below the normal threshold of a radio and use of the squelch will eliminate the noise. In tests, I need an antenna within 1 foot to cause any problems, so I would ask if the customer could make sure the antenna is not really close to the Nav lights. Usually the issue is a loose or dirty light socket. This is where cleaning the socket and the dielectric grease really helps. If the radio has auto squelch it will totally remove squelch when tuned to very distant stations and then you may pick up my lights. As you get closer (stronger signal), the squelch increases and the issue will go away. If you are tuned to a station with no signal, you will not hear my lights since the default squelch is usually about 10% of radio sensitivity.
When these lights are in strobe mode, do the red & green nav lights still illuminate between strobe flashes?
Per the supplier: No. There is no light output between light bursts.
Do these carry any kind of warranty? If so, what are the terms? I think just about all my customers would buy these.
Yes. The manufacturer offers a 90 day satisfaction guarantee.
Will the bulbs in this kit replace a Grimes 1512 bulb?
Per the supplier: Yes, my Sextant 30w kit (11-11987) contains bulbs that are a direct replacements for the Grimes 1512 bulb.
Are the Sextant Nav System With Constant + Fast Strobe 30w lights approved and legal for other than experimental aircraft? For example, can I legally use them on a Cessna, Mooney or Piper?
The Aircraft Sextant Nav System With Constant + Fast Strobe 30w lights Meet FAA AC No: 20-74 and TC Part V - Chapter 523, Subchapter F, 523-VLA.1393 requirements but is not FAA/PMA Approved. FAA Approval paperwork is not available.
I currently have wing tip and tail constant nav lights, with no strobe function, so its just a simple on/off switch.
I have a separate belly strobe which I want to remove
If I replace the bulbs with your system, how does the strobe function work with a single Nav light switch?
this nav light system (11-11987) is able to be operated from a single switch. Turning the switch on once will activate the constant lights, turning the switch on twice within 3 seconds will activate the strobe light.
My 1977 Cessna 150M wingtip bulbs are #A7512-12 and the tail #1777 (from the parts manual). Will these be compatible?
Yes, however these are not approved for certified aircraft.
It seems to be advertised as a replacement for almost all GA aircraft but is not FAA approved. Can it legally be used to replace lights on my certified aircraft?
No, the Navstrobe NAV system (11-11987) is intended for use in experimental aircraft only.
Do the NavStrobe Sextant lights need a power supply to work?
No. These bulbs do not require a power supply. They are replacement nav light bulbs only with a safety feature that flashes. They are designed to be plug and play in your already installed aircraft lighting system.
