The difficulty is that in other countries they're called different
things.  The ones used in the side lights and indicator side repeaters,
as well as the instrument backlights is a fairly big fat bulb about the
size of the top joint of my pinky.

The ones I meant are about 4mm x 13mm and are the same as the ones used
in the panel lamps on an RL02.  Guess where I got the spare bulbs for my
RL02 from?
