how to do effect light for logo
please tutorials
thanks

Photoshop -> layer -> glow -> set color and pixel amount

Done.

You don't define - program. Maybe gimp....
GIMP - filtres - light and shadow

I'd first try to ask your friend Google.
There are glowing lights as .psd to download. You can insert them and set them wherever you want. (I hope you get what I mean)
Or you can generate artificial light by double clicking the layer you want to add a glow/light at, tick the box at "glow" and set it as you wish to.
