So, one strobe, one landing light, and that will be all. I found an interesting strobe light, 12V, Xenon lamp, for about $14. It is a sealed unit that they use in industrial applications. You probably can find them at any radio shop. And believe me, they work better than a Cessna's! I intend to mount it under the belly, aft of the wings.

The only thing that worries me about them is that the flash rate is pretty low. You get two flashes per strobe head at a rate of 66 TOTAL flashes per minute, which means 33 "flash pairs" per minute, or about 16 per side per minute, which is one double flash every four seconds. That's a pretty long time between flashes, and easily missed in somebody's scan. I still plan to install the whole system, but later on I plan on upgrading to a Whelen power supply that will flash them at a much faster rate, and brighter too. These strobe heads can be used with the Whelen power supply, so I was told by the guy that makes them. Because the Kuntzleman kit is intended mainly for ultralights, it doesn't come with shielded wire either (but he might substitute if you ask for it), which is highly recommended. I found some shielded 5 conductor wire that was left over from a Space Shuttle job for mine. I've already tested my strobe setup, and had to be careful about where I located the power supply. See the bottom of http://home.hiwaay.net/~langford/kpanel.html for details...

I placed it a little high up the rudder because I wanted pilots taxing behind me to see it. Bobby Muse ------------------------------ Date: Thu, 6 Sep 2001 07:57:04 -0500 (CDT) To: "Ross R.

T/C's are very sensitive and must be properly installed. All connections on a t/c must be air tight. Even a small crack in the insulation on a t/c wire can cause incorrect readings. Air and relative humidity getting to the t/c wire or connection is a bad thing and will cause faulty readings. Check the wire for cracks and seal all connections with silicone.
