In addition early models had screw in bulbs, these are rated at 18V.Gizzy said:They are usually 5 V or 19 V lamps and are usually powered via the Circuit board.
They have a flat top or a domed top and from memory the flat top ones are 5V lamps....

Just for complete accuracy, the round topped modern (twin prong) ones are 24 volt rated to accommodate both analogue and DCC peak voltages. The older screw in bulbs are 18 volt rated, so get a bit stressed by DCC unless you reduce the chip output voltage somewhat.
