Los Angeles is home to a number of interesting and historic buildings, and one in particular was going to give the owner a shock. Clifton’s Cafeteria was to undergo a makeover when they noticed a neon sign that was still turned on. Aside from how old the building was, when experts came to see it, they believed that it had been on for over 77 years, making it the longest in neon light history. The owner thinks it had been turned on since 1935, which means the owner must have paid over $17,000 in power bills!
