My light modules have accumulated dirt and grime. I took out the module, but could not figure out how to open it up. It seemed the plastic was 2-piece, but had been heat sealed. Is there a way to get in to clean it that I'm missing?

 

you need to put the lightin the oven and heat it up until the glue comes soft and then pull the light away from the housing..im pretty sure theres a write-up somewhere around here.
