Loose parts - that's why it is called and sold as a KIT

False advertising!
Buyer beware! Damn thing comes in pieces, not fully assembled as shown. Get you solder gun cuase the resistors, capacitors, lights, etc all come loose. Much assembly required! EDITORS NOTE: That is why it is called a KIT....

Great Kit
Just finished one of five I bought, took less than an hour to complete. I bought these to make railroad crossing signals , but am trying to figure out how to display them without the board showing?
