How is it possible for rotating lights attached to objects?

How can I set this light which is attached to this player shape to face forward instead of up? I used attachtoobject to attach the light to the player shape. Any ideas?

I tried to change the rotation but it didn't seem to do anything.

%light = new volumeLight() {
      dataBlock = "sgMountLight";
            //rotation = "-0.357694 0.933839 9.9834e-009 180";
            rotation = "0 0 1 0";
            scale = "1 1 1";
            dataBlock = "sgMountLight";
            Enable = "1";
            IconSize = "1";
            ParticleColorAttenuation = "1";
            Texture = "common/lighting/lightFalloffMono.png";
            lpDistance = "0.35";
            ShootDistance = "5";
            Xextent = "0.6";
            Yextent = "0.6";
            SubdivideU = "4";
            SubdivideV = "4";
            FootColour = "1.000000 1.000000 1.000000 0.182000";
            TailColour = "0.000000 0.000000 0.000000 0.000000";
   };
   
   %light.attachtoobject(%obj);

This is simply code copied from the swinging light in the TLK demo. Of course that rotation of "0 0 1 0" isn't going to do what I want. That's just there to show where I tried to set rotation at.

The light will rotate with the hand during animations, but it always points up the arm. Any idea how to point it forward like if this was going to be for a flashlight ?
