Hey Prof, thanks for the feedback man. Could you please review the thread I have at Ausmicro.com about this project. You can see it here:

I've managed to fit all the circuitry (using SMD of course
) on one pcb that I've etched by hand. I'm looking at a quad 2 input OR gate package instead of diodes for the 4 middle LEDS to be able to isolate the two (left/right) channels.
How do you power yours? If you're using the NE555 you need a minimum of 6V yes? I'm using the TLC555 (cmos version) that runs at 3V. My pcb includes a 1.2 -> 5V DCDC convertor circuit and I run it off the car's battery.
There are some photos on the ausmicro thread.
Cheers,
