Hi Khalifa, See if this sample file helps: https://svn.blender.org/svnroot/bf-blender/trunk/lib/tests/gameengine_visual/lampRGB.blend
The code runs in the BGE (Blender Game Engine), but the BGE works the same for Blender and for the BGE. Apart from that BGL is simply a wrapper of OpenGL functions, so I presume the error is in your OpenGL (bgl) code.
