My wife has a Focus 1800 Zetec Diesel, she loves it but will have a new one very soon, a Focus Titanium. 2011 model
Is it easy to fit these bright headlight bulbs, the bluey ones we see on other cars, are they named xenon?
Apart from Ford, where would she get them from and would I be able to change them?

She is also looking at the Fiesta Titanium but I am quite a size and doubt if I will be comfy in one, any advice welcome.

Thanks.
