Aside from automotive work, I spent 20+ years building custom electric signs, I did quite a bit of work for theme parks like Disney and Universal Studios. They're pretty picky, especially Disney who have their own electrical and mechanical engineers to spec out how things are to be built and they inspect everything before it gets installed. Things have to be strong due to liability issues and have to look good because they get seen by tens of thousands of people everyday. Someone(Florida sign guy Dwayne H) made off with most of my pictures. Out of hundreds of sign pics, here's what's left.
Outer Limits I did two of for two different Theme Parks based on the TV Series.
The Harley sign is about 30x30 foot and 90 feet in the air. I built the neon lit letters and spotlight lit letters, two sets each for the main signs going into Disney.

Sega and STP went to Daytona Speedway. There were two of the STP pieces in the pic, plus two arches to connect those and make a complete circle. It was hung from the ceiling along with a fiberglass resin covered, sculpted foam, STP bottle done by someone else. Sega Speedway is/was the Arcade.
