The closest model of a conventional school bus I've found for 1/48 is the Sunnyside 9852. The 1/48 Circuscraft sitting children figures fit OK.
3mm white LEDs for headlights:
3mm white LEDs on the ceiling for interior lighting:
red and amber 0805-sized surface mount LEDs pressed against the upper flasher front and rear lenses:
I should have made this externally controllable with control wires to trigger the action, but it is just an on/off switch powered by one AAA battery which is all that would fit under the seats. The 1.5V is stepped up using a boost regulator to about 4V which is needed for the white LEDs. The guts are fairly involved as DIY hobbyist projects go requiring programming of a microchip and fabrication of a circuit board to cram in all the parts:
Some other add-ons are engine sounds and children laughing, and a swinging stop sign synchronized when transitioning from amber to red flashing.

You never cease to amaze me with how much you can cram into the smallest spaces. This has got to be coolest school bus in O-gauge!
