I bought part # AR111-CW9W-30 from SuperbirghtLEDs.com. This is a drop in replacement for GE-4509 100W landing lights I used in my KR and SuperCub. Both planes had the landing lights mounted with this kit from Aircraft Spruce: 11-08000 LEADING EDGE LANDING LIGHT KIT. Just removed the 100W lights and installed the 11W LED lights in their place. Haven't flown them at night yet, but they seem a bit more intense as recognition lights with the wigwag. These lights are available in both cool white and warm white colors.
For the last 18 years I have always smelled hot plastic when the landing lights were on; even on as wigwags. I've never been able to determine whether I was smelling hot wiring or hot plexiglass lenses and have never found any heat damage to the wiring or landing light covers. But regardless, I don't like smelling hot anything while in the air. Additionally, with a generator rather than an alternator, my battery was usually pretty well depleted by the time I got to the ground after throttling back on approach, so I often times ended up landing with very little light from the landing lights. The low draw (11W) LEDs should address both issues, which is why I changed them out. My SuperCub has a 60 Amp alternator, so the draw of the landing lights isn't really noticeable. I don't have plans to change out the landing lights on it any time soon unless I find that I really like the lighting on the KR when I get around to testing it at night. -Jeff Scott Los Alamos, NM > > What part number did you order and what kind of back do you need to hold > that light
