Unfortunately not.
If you have access to a 3rd party video editor, I recommend that you render two versions of your clip (one with the lights turned on, and one with the lights turned off).
Make sure you render the 2 versions of your clip as image sequences (PNG format = best quality and the lowest file size).
Then fade between the 2 clips in the video editor to make it look like the lights are fading in.
