light_x,y is point of light
target_x,y is target point
dir_x = target_x - light_x
dir_y = target_y - light_y
dir_x,y is now the vector from the light point to the target point. Now normalize it:
len = sqrt( dir_x*dir_x + dir_y*dir_y )
dir_x /= len
dir_y /= len
(of course check for division by 0 before doing this)

thanks,
ok things have worked out great,
ive implemented the light into my engine
and things are working perfectly,
here are some screen shots
they are from the game im making,
it's entirely 2D
this screen shot uses the GDI adaptor
*my graphics engine uses a common API adaption interface
to make it graphics api indipendant*
before any lighting *day scene*:
