10 X OO Gauge Head Lamps Model Railway White
these lamps come with 10 gems which can be stuck on but the lamps also are hollow inside so could be fitted with a micro led or fiber if preferred
the hole underneath is 1.5mm
You can place these on Bachmann and Hornby locos lamp irons (steam) without the need of gluing them in place I have had mix results with diesel as long as there is about 1mm clearance between the back of the lamp iron and the loco you should be fine.
PLEASE NOTE GEMS ARE NOT STUCK ON BEFORE SENDING
