This is a selectiond of typical LU Fog Repeaters and Rail Gap Indicators along with some Fixed Red Light signals. These all come with ladders and posts, or can be mounted on the 2.4mm supports for the 2 aspect signals available in this shop. The LEDs should be surface mount (SMD) for these, as the size is quite small. I have had success with http://stores.ebay.com/WEHONEST/SMD-LEDs-/_i.html?_fsub=11170793012&_sid=149381402&_trksid=p4634.c0.m322 for pre wired SMD LEDS
