The yellow and green bulbs below the seats were transferred over from the Scrambler after it's refurbishment in 2016. The current lights look new and appear to be LEDs.

They were. The Eiffel Tower was originally floodlit with bright halogen lamps before switching to the colored LED lighting. The uplighting surrounding the Tower was removed prior to the 2017 season. 

Those colors look awesome! Now all we need is for the yellow tubes to return to the rotor at the top (please please please please please Kings Island just do it!!!!!)

I'll post a longer rambling either tonight or tomorrow after I hopefully get my second ridethrough in.  This was an amazing ride! There were so many Easter eggs that I noticed and even more new things overall! I don't think anyone who's ridden it could call this a Boo Blasters reskin or anything of the such anymore.  Some spoiler-ific things below including both good and bad things! I'll try to not repeat what others have said, but apologies if I do. I think I'll like it more as I ride it more, but I'm glad it's back     IIRC for the first few days they had return time tickets that helped the queue line feel quick while ensuring social distancing could be observed. I think I might've waited an hour before my first ride on/around July 2nd or July 7th (whichever day the park opened that year).

Good eye! I always wondered.. Were those fixtures used as nighttime downlighting back in the day?   I love the new season threads. I grew up in Cincy but moved to Oregon 4 years ago, so I don’t get to the park very often anymore. It is always fun to recognize small changes like this!
