The document describes a low-cost bicycle indicator kit that uses common electronic components to provide a substitute for commercially available versions. The kit uses a step-down transformer to convert 230V AC household power to 12V AC, which is then rectified and filtered to produce a regulated +9V DC output to power the indicator. It works in a simple but effective manner and is convenient for users.

2. The kit bicycle indicator described here uses
low-cost components and is a good substitute
to many commercially available versions. It
works in an extremely different manner and is
convenient to operate. In the kit Bicycle
indicator the first block is power supply in
which the input is 230V AC which is step down
using the transformer (12-0-12) .The 12V ac
input is fed to the bridge diode to gives 12V
pulsating DC. This DC voltage is filtered through
the capacitor to remove the ripples. The filtered
DC is fed to 7809 regulator to fetch +9v
regulated output.
