I am looking for a font made of block letters comprised of a box with light bulbs inside, kind of like what you would find in early 1900's signs in France, The West End, or Broadway.

A sans serif version of this: http://youthleaderstash.com/wp-content/uploads/2012/01/diy-carnival-marquee-letters-3.jpeg

Perfect! You are a genius. Thanks!

You're welcome.
