I have not really looked to see what can be done to keep the function the same.

Thanks Jeff - great analysis; no wonder the flashers and signal lights were erratic when I tried the LEDs in the front park/signal light sockets. I am going to delve into this further as well. Looks like some digital switching circuitry (to address the AND-OR functions) might be required between the lights and the control signals.
