yes they are H11 mate.
Just dug this up,
Well thanks for that Lenny, been doing my head in the last couple of days. [regards my plan to convert the fogs into 5w or 7w Cree LED DRL's]
The Owners Hand Book states they are H11, but when you go on eBay and use the "Compatibility Checker" some sellers use. It says not compatible, well I've had the bulbs out, measured them depth and width wise, look alright to me.
Today I email one supplier, they told me to use http://www.pal-guide.com/ to check. Input model details, it came back saying the were H8. So I went and looked at some H8's popped them through the "Compatibility Checker" and yes you guessed it, it also said they were not compatabile. H11 or H8 they are all incompatible as far as it's concerned!!!
Edit: out of interest what wattage were those Cree's you fit ?
I have a pair of H11 Cree fog light bulbs for sale if interested...
I've listed the ad but mistakenly listed them as H8 instead of H11...duh!!
Mk2 Focus are H8, MK2.5 are H11.
Actually bulb are same, but watts are differend, H8 is 35W and H11 55W :)
