I installed the lights and gave them a try in the hanger at night and the brightness was a bit more then the stock lights. The big test was when I turned on the communication radio. The squelch opened and lots of noise with the lights on full and less noise when flashing. The next day I flew the plane and tried them on and off several times and there was no noise at all. I left the power on after killing the engine and got out to see if the lights were flashing and yes there were on. No noise on the radio. I dont know why there was radio noise in the hanger with the engine not running. Maybe the WIFI next door and the lights had a frequency that created radio interference. I will try again in the hanger. Over all I am happy with the lights.

Aircraft Wingtip Nav Light 5W-A-1512

Very bright, like the strobe mode, work as advertised

Very bright strobe / Nav light. Low amp draw to alternator. Great product.

they work great. very bright.

These are at least 50% brighter than the standard Grimes 14v Nav lights and they are a whiter light also. Durability to be determined. I think they rock. The strobe model is great too. It may give you anti collision light capability if your regular beacon burns out you can switch to the strobe mode on this model. Basically a back up anti collision capability. Beats the heck out of paying $1200 for a set of LED fixtures and they fit a standard Grimes Nav light fixture.

Works as advertised

Everyone should keep in mind that flashing nav lights are NOT legal (homebuilt or cert.) The nav lights should be solid on steady.

A little more pricey than some led nav lights but very easy to install. The strobe function doesnt always work. Once they get warmed up I cant get the strobe function to work at all.

When in strobe mode, they create a high level of RF interference which the COM and NAV radios pick up. If you are talking to ATC, you will not be able to hear them when the LED is in strobe mode. The frequency that is most affected is above 120.00 MHz. It seems that at 119.9 and below, the interference is far less. Operationally, they are bright and easily fit in my standard NAV light mounts. The strobe mode is very effective.

I installed in a Cessa wingtip and look great,they cause static on aircraft radio when on

Mine lasted about two years and failed.

Very bright but causes so much static on 2 X KX-155 had to remove. Spent considerable $$ on vendors recommended fix but in the end went for another brand as the static was never resolved.

Cessna 175B I bought a set of these and they worked for 5 minutes ok on the battery, 12.7 volts. The 1st time with the engine running, buss at 14.2 volts, both failed almost immediately. I returned them for a replacement set. On the battery both had leds not lit. I returned them for a refund. Ill go back to standard bulbs.
