Veroma is a German company specialising in accessories for 1:14 & 1:16 scale model trucks. Parts include lighting (spotlights & beacons), chassis parts, wheels & tyres, axels etc. All are of superb quality and really enhance your model. Unfortunately Veroma will no longer supply many of their excellent products direct to the hobby trade as they have sold all their production of 1:14 scale items to Carson for distribution. Unfortunately it is almost impossible to get truck items from Carson & their importer in this country.
Here is a link to a video made by my friend Tim, demonstrating the beacons: http://youtu.be/gxOp9k7cM00
