Don't worry about the ENTIRELY SELF-CONTAINED solar powered lights 
that typically are a single LED (or two), with a solar cell on top 
and a pair of AA's inside. These are harmless. 

You're looking for things with antennas attached, or that are 
connected to the power line. To understand what I mean by antennas, 
see the RFI tutorial on my website. It should give you some more 
troubleshooting ideas. 


Yes, those "electronic transformers" are VERY nasty RFI sources.
