When the LEDs are connected using serial circuit,
if either one of the LEDs does not light up, then
current will not flow causing the other LEDs to not
light up. In the new design, the LEDs are in parallel
with the zener diodes. If either one of the LEDs
does not light up, current can still flow through
causing the others to light up.
