Reply to SL1200 target light

I recently found a Technics that's cheap enough to get me interested. the problem is, the target light is busted.

Is this thing important or I can do without it? I have searched the net for instructions to change the target light and i know it only shines light for the needle. any more function of the light to be of great importance? let me know please.

thanks.

If ever, this will be my first Technics and Turntable
