As far as I can tell, these small bulbs are identical to the Lucas 4W pilot bulb (Item1162), other than these are of a slightly smaller wattage - 2 Watts instead of 4 Watts. The Lucas description indicates that these are Instrument bulbs - rather than the 1162 Item (which are described as Pilot Bulbs) - but I would expect they could be interchanged if you wished to use a stronger or weaker bulb.
