These are to be attached to the stock I have been building recently. The red lense lamps are to go on the Brake Vans, the silver lensed ones to locos.
An alternative is to use ready made 2mm Scale lamps produced by Springside.
These come on a card, stuck on with double sided tape so removing them must be carefully done.
One advantage of the Springside offering is that they are attached to the sprue with a stalk.This I keep as long as possible and attach to a loco footplate by
drilling a similar sized hole and just superglueing in place. Springside do a fair range of lamps in different company styles and scales. The ones I have used are for GWR and BR types.
The difference in size can be seen, I am undecided which is the best in the way of scale although the 2mm offerings are better detailed. Your thoughts would be appreciated. I must post a comparison when they are fitted to their intended wagons.
