Gary,

You are correct. Removing the ballast would be optional, the advantage being the weight loss.

The landing light whine will go away with the LED conversion.

The Max Pulse unit will pulse any type of landing light. The weigh only grams, have multiple settings and are fairly economical. Something like $300. Also, for the certified guys, they are STC'd for PA-18 and CC18, among many other aircraft.
