Hi,

I'm not so sure, but it looks like an Infrared Sensor. From the casing it has, it can also be a LED. It would be best to test it and see the output. Also, you can ask your friend what it is since you got it from him/her.

Hi Sourav Kumar,

I think it is an old type of indicator bulb mostly used in older models of color tvs as channel indicators which works on a max of 22v anyhow dont apply 22v .
check the resistance of the bulb with a multimeter, apply dc usig a variable power supply
vary slowly from 0 to 12v. these bulbs were use during the year 1980 to 2000.after that
i think it disappeared fr the market.
