Moving light on image Script

[LIGHTTY]

I use IE-6 and can't get this script to work on my Website ?/
http://thelightofdayradioshow.com/

You see the Cosmic-looking image on top ?? I can't get the script to make it happen ?? I only understand LIMITED html coding...

Here's all the coding I used-<style>
<!--
#Inbound Red Comet of Doom{
filter:light
}
-->
</style>

<IMG id="Inbound Red Comet of Doom" speed="30"
