Diplomacy aside:

The problem as stated is to switch between two LEDs. 20ma or less is typical.
I happen to think (at this time) that my circuit is best because it will work off of a single supply voltage of 3 to 24 volts by changing the resistors (at the extreme voltage ends),
and not requiring any extra current, to drive a relay, for example.

For switching AC or dirty voltages and/or high current loads, yes, a relay is a very good choice. If you have a small low current relay handy and this is an automotive application then a relay is a good solution to the problem.
