    This LED light works great, much brighter than my previous bulb. Straight forward replacement bulb. The strobe function works just as described and is a great addition.

    Although it is not installed yet this is the best value for a tail strobe that I found. Thanks

    This works great. Very bright and basically gives me a 3 light strobe system. If your battery voltage isn't fully up it might not strobe if the engine isn't started. As soon as your alternator is on line it will work ok. The side lens was loose on two side but I used a tiny bit of clear silicone glue to set them back on and it's fine.

    Q: Do these strobe lamps require a power supply box or are they self contained? ie. Do they run on just 12v without a capacitor?

    These are just bulb replacements. They are intended to replace the bulbs currently used in your aircraft. They are self contained and do not require any power supply modification.

    Q: Does the tailfin nav strobe bulb function as both a white tail lamp and a strobe light?

    The NavStrobe tailfin bulb is a replacement for a tail light lamp, but does not take the place of a strobe with a flashtube. The flashing option is a safety feature, but not a replacement for a strobe assembly.

    Q: Are these lamps FAA-PMA approved or are they just for experimental use as your other bulbs state?

    This bulb is approved as a replacement bulb for tail lights only with the added strobe safety feature to be used at the pilot's discretion. They are not approved as a replacement for an anti-collision system. They do not have FAA-PMA approval but as replacement bulbs only they are not required to.

    Q: Do the NavStrobe Aircraft LED Tailfil NAV Strobe light 7.5W-A-1156 work in a 28v system?

    Yes, these can be used with systems at 8-30 volts.
