That's like saying they would have developed the internal combustion engine and built a Ford Pinto too. Why would any organism that evolved like humans discover any technology similar to that on earth? Technology would likely be more dependent on environmental influences more so than based on evolutionary influences.
Looking for emissions of energy radiation I can see. Looking for artificial sources of light, or identifying wavelengths of light would make sense. But the specifics of looking for evidence of LED light, seems way too specific. It's like looking at Mars and say you're looking for the existent of purple majesty potatoes. When you're looking for evidence of something broad you don't start focusing on on specifics.
