REFLECTOR: Fwd: Composite Designs Landing Gear Controller Dimmer?

[Brian Michalk]

It should be a pulse width modulated dimmer.  You can easily make a 
circuit that does this, and you'll spend more than a few hours getting 
it right.

I make almost all of my circuit boards, but for this, I go off the 
shelf.  This is what I use.
