Construction Arrow - Trailer - HO 87:1 Scale

HO 87:1 scale road construction trailer with Arrow.  This model is designed to accept (15) 0402 SMD LED's.  The  0.6mm diameter holes through the center of each post are capble of holding (34) #38 AWG insulated magnet wire strands.  This means you can wire each LED individually or better yet you can make an animated scrolling /flashing sign by using the schematic in the attached picture.  The size of these LED's (1mm x 0.5mm x 0.7mm are very, very tiny and assembly is going to be tedious and possibly difficult.  Therefore this model is not recommended for novice modelers.
