I've got light fitting that has the cover retained by some tamper proof

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.

I got a box of security bits from Aldi recently. 104 different ones I
think, for 5 or 6 quid. Quality was not the best, but how often do you
need one of those obsure shares/sizes? Worth keeping an eye out for
future reference.
