I knew it had "lyte" was associated with it, but until now, I thought it was the manufacturer rather than the product name, as per the comment from Joe Kaminkow on IPDB. It's tough to find something named "lyte" without another piece of identifying information. Clyde combined with Lyte was the key.
Quoted from woody24:Seems like it shouldn't be that hard to convert it to something that looks like the LaserWar topper.
You would still have to make a vacuform mold for the data east style box, and find some smoked glass to cut to the right shape to fit the box. It looks like the glass is riveted to the case.
There's also what looks like holes on the side (in the laser war flyer), and I'm not sure what those are for.
On IPDB:
The manufacturer flyer shows a trapezoidal backbox topper with a spinning red LED board to create an optical effect. Joe Kaminkow told us that the light itself came in a square black box, approximately 12 by 12 inches, made by a now-defunct company called Lyte. Data East added a custom trapezoidal housing around it for mounting on the backbox using screws. The spinning LED display did not operate in concert with game play. He wasn't sure if it got its power from 12 volts from the output of the sound board or if it had a 110v line cord. Joe said the topper was too expensive and was discontinued during the production run of this game. He guessed about 500 of the earliest machines came with this topper.
So, a few pieces of info in that comment are incorrect at least--the Lyte name, and the number of them made (I keep hearing the number 10 thrown about--not 500).
Also, it seems odd that the device would not be connected to the sound system in some way considering it is a sound visualizer (and that this was the first stereo sound system). I really want to see if @aberdeentp's topper has a cord that would connect to something in the game.
