I was browsing Petsmart across the parking lot from my work the other day and stumbled across this light kit and decided to toss it in my basket. Wasn't looking for anything in particular but the lights came out real nice. Here is a video I did real quick to showcase the lights. I got them in green and red. The overhead blue light is something else. I forget who makes it. Anyway, I thought you all might be interested.
