Thank you so much, now when I made some test front short and long lights

The other day I found this toy at a flea market, I changed the cables, I've cleaned and works perfectly, I put some photos

As you can see is a military reflector, is the right size to attach it to the truck, I have to modify the hitch wearing and not if you change the wheels by other larger or only slightly lower the shaft relative to the rest of the trailer that the proper height for the truck, also'll have to make some tinkering paint and others, in order, the first is the bus, greetings and thanks again
