This is one occasion where a lookup by numberplate would be
appropriate.
Although I've not had a lot of luck with such searches recently.
According to the gadget in Halfords last week my car only has rear
wiper blades (I wanted front) and only has headlight bulbs (I wanted a
brake light).

I had better luck in Eurocarparts in Wapping the other day for wipers
and some bulbs - the counter guy left his post to go look at our car
and didn't trust what his computer said....

I went and got the old bulb and found the right one by eyeball. Ordered
the wiper blades from eBay after being given an eyewatering quote (for
unbranded) from local car accessory shop.
