I'm sorry i can't post pictures right now, but a quick googly will show you.
I think Steve at the Ultimate Garage has them if you in the USA.
They are made of a very tough plastic and insert into the socket. I have been using them
for 5 years and they work superbly, just a quick glance is all you need to find the right size.
They don't fade or wear out when they get all oily, and a qucik wipe with WD40 brings
them up like new.
