It's the home of the Indianapolis Colts and bears the name of a successful Hoosier businessman, but Forrest Lucas isn't happy about a glaring problem with Lucas Oil Stadium, which he paid more than $120 million for naming rights.The building's nighttime appearance has a major problem in the eyes of Lucas and anyone else who sees the nearly $1 billion facility after dark, 6News' Rick Hightower reported.The sign that bears the name of the building and the sponsor isn't working correctly, making "LUCAS OIL" appear as "IUCAS OII.""Apparently somebody dropped the ball again, and I've got to tell you, I'm getting pretty peeved about it," Lucas said in a phone interview. "I would think everybody in town would be getting a little peeved about it."Lucas said he's been getting calls about the lighting problem for weeks."I don't blame the Lucas family for being upset," said John Klipsch, executive director of the Stadium and Convention Building Authority. "I don't blame the Colts for being upset. We're upset. We want the sign company to complete the contract and finish the work properly."The fix isn't as easy as changing a lightbulb. It involves design, installation and construction issues, Klipsch said.Lucas, who spent a lot of personal time and money designing Lucas Plaza inside, said that while he's disappointed and upset, he's still happy about the naming rights deal.But Lucas said that if he had to do it again, he'd ask a lot more questions."This is the crown jewel of the city and the state, and it's sitting there looking ridiculous with half the lights out on the building," Lucas said.Stadium officials said the lighting system is under warranty and can be fixed at no charge for the first year. They insist the sign will be fixed before the beginning of football season.
