LED the GI and be done with it.
LEDing the controlled lamps will require an addon or replacement board.
I would put LEDs into the pops. Those lights frequently burn out because of the vibration and heat. Not great for the caps either.

This is because the bayonet socket on pop-bumpers has a pretty crap design, and doesn't make good contact with the bulb. Over time, dirt/corrosion adds resistance to the connection, and the socket becomes loose, so this acts as a resistance between the bulb and the power-source. Resistance + current = heat, which cooks the bulb. A hot bulb will slowly evaporate the filament which then deposits metal inside the bulb, which causes the heat to build up even more. Result, is a runaway situation and a nice black/shiny bulb. This can happen with any poor socket, but the cover of the pop-bumper (which keeps the heat in) makes it even worse, and the poor design of pop-bumper sockets makes it doubly worse.

That was great information...thanks!
Since the popbodies are built as they are, it's hard to get a newer holder with bulb inside unless pressed sideways.
Any tip on this?
