Light Switch with glow

I have altered a light switch script to include the glow as well as the light when the object is clicked. I have put the script inside the rout prim.

Problem is when I have more than one of the lights up they all do not work, the flow comes on but the Light does not, and when you walk up to the object the light comes on??

here is the script can anyone tell me what is wrong


//Title: Light Switch
//9-01-07

//Simple light switch. Click object with script turns light on and off.

integer light_switch;
vector light_color=<1,1,1>;
float light_intensity=1.0;
float light_radius=04.0;
float light_falloff=1;


init ()
{

//Set light to off initially
light_switch=0;
llSetPrimitiveParams([ PRIM_GLOW, ALL_SIDES, 0.0,PRIM_POINT_LIGHT, FALSE, light_color, light_intensity, light_radius, light_falloff]);
llOwnerSay("Set to midnight and click to toggle light!";

}

default
{
state_entry()
{

init();

}

on_rez(integer start_param)
{
init();
}

touch_start(integer total_number)
{
if(light_switch==1)
{
//Light is on, turn off
llSetPrimitiveParams([ PRIM_GLOW, ALL_SIDES, 0.0,PRIM_POINT_LIGHT, FALSE, light_color, light_intensity, light_radius, light_falloff]);
light_switch=0;
llOwnerSay("Light turned off.";
}

else
{
//Light is off, turn on
llSetPrimitiveParams([ PRIM_GLOW, ALL_SIDES, 0.3,PRIM_POINT_LIGHT, TRUE, light_color, light_intensity, light_radius, light_falloff]);
light_switch=1;
llOwnerSay("Light turned on.";
}

}

}

You are limited to a certain number of local light sources. Can't remember the hard limit, 6 maybe?

There are only 6 (or even as few as 2) available prim light sources, depending on your SL version and video card. Only the closest ones will show as lit. Face lamps, and other local lights in the area, will eat away from what is available for use in your object.

Eventually high end cards will have no limit (that comes alongside the work LL has been doing on shadow support), but it will be a while before that becomes an official feature, longer before we can depend on many people being able to see things that way.

So, you may want to make do with alternatives like the glow, full bright, maybe a bit of particle stuff, to fill in for what local lights can't really do just yet.

That explains a lot thank you very much, and I thought the script was wrong. Thanks all.
