Yes.  Her Majesty's fuzz are now using these bulbs in both liveried
and 'stealth' vehicles.  They're distinctive when they approach from
behind because the lights are not only this particular colour but are
also properly aligned.  If you see the same colour but poor alignment
(usually very different heights on different sides) you know you only
have a prat approaching.

It really is a strange correlation - it's been on my mind for a few
weeks - why would someone want to spend $$$ on bulbs when spending $
on alignment might be just as good?
