I've got light fitting that has the cover retained by some tamper
proof screws. The heads have a raised equilateral triangle with each
side 4 or 5mm long. This obviously needs a triangle shaped socket
driver, can I find one? Can I heck. That's looking on CPC and RS
sites. The "security" bit sets don't have this particular type of bit
in them.

Any clues? TIA.

Dunno how big the triang is but... :-)
