    Hello,

    I don't know much about neons, I mean there operating voltage, current & power etc.
    I can work out resistor, capacitor, wirings etc . But want to know any precautions for neons.

    Thanks.

    Neon tubes need a fairly high voltage to "strike". The actual value depends upon the particular tube, but the lowest is around 60V.
    They also need a current-limiting resistor, which can be quite a high value, in series with them.

    In this respect they function much like a zener diode.

    You can't get a neon to strike with 12V.
