Spare B1 - 0148X Twinkling bulbs

Spare bulbs suitable for the following light sets:
Carnival 40 set
Carnival 80 set
Carnival 160 set
Melting Ice 160 set
These replacement bulbs have a Red base. Those with a Green base are B1 0148C - and care should be taken to replace with the correct bulbs. Certain twinkling sets do contain both bulbs. As B1 0148X is the twinkling bulb, without one of these bulbs in each line the set will fail to operate.
