This works ok as long as your grounds are all cleaned up. The more LED bulbs that I put on my plane, the more my Garmin comm starts to freak out. I noticed its on the borderline of squelching and as soon as you turn off an LED or two, it goes back to being crystal clear.

Nice idea but useless for aviation because of the rf spurious the led produces which opens the squelch of your comm equipment. The bulb attachment to the housing is very fragile and needed resoldering..
