First, I am not an expert builder of small kits lit this. Second I will include both the short cabinet and tall cabinet since I bought both and they are the same kit except for the cabinet itself. I also installed the LED0001 into the signal head. These are definatly well constructed and quality pieces. My only criticism would be that the nub on the arm could be a little bigger to afford more glue surface for the signal head. I found in handling after the signal head was mounted that I had 2 of the 4 come off, requiring regluing. My heavy hands and a little learning. I also managed to put a slight curve in one of the brass tubes as I filed for the hole for the LED wires, Just a warning to others. This is my heavy hand not a fault of the kit. The LED wires are definatly very fine and do completely disappear after painting the final assembly. I soldered some wire wrap wire to the ends so that I could connect the wire to screw terminals on the circuit board I used. By using colored wire wrap wire I could see which wire was which under the table in the less than ideal light. These were used to indicate the proper polarity entering and exiting reverse loops on a DC HO railroad. The finished product is very attractive and I would recommend them and would buy them again for another project.
