Shader to Show cutout texture at full brightness? Help would be really appreciated :)

Hi

I cannot find a shader to just show a cutout, but to have it at full brightness so it is for some bright sprite type things. The scene is dark but these cutouts need to be lit up, preferably without pasting a light-source on top of them.

I may be misunderstanding something very fundamental but as far as I can tell it may be because the Alpha channel is used for illuminating just parts or something.

If anyone could point me in the right direction here it would be most appreciated, this is possibly my only use for a custom shader.

Thanks, Rich
