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.
