1 watt and 5 watt LED for Nav lights?

To Jim Weir and Group

I am interested in using the new (to me) 1 watt and 5 watt LEDs for
nav lights.
Not having to worry about changing bulbs or the power requirements are
very attractive.

I have seen some posts about leds but would like to tie it all
together.
I know of two sites showing their versions and one is using 9 LEDs
while the other is using more.

What it boils down to is this: how many leds for the the right and
left wings, how many for the tail and can the leds be strobed or any
thing else I don't know?

Thanks
Bill
