Can you fit LED bulbs to the Focus Mk3?

This car has halogen headlamps. In the UK, a halogen headlamp unit on a car first used on or after 1 April 1986 must not be converted to LED or HID bulbs: the MOT inspection manual (§4.1.4) treats a converted unit as a fail, however bright or well aimed it is. “Retrofit LED H7” bulbs sold for these cars are for off-road use. Halogen upgrade bulbs (+150% and similar) are legal because the unit is unchanged. Sidelights, indicators and number-plate LEDs are a separate question — E-marked LED versions of those are road legal.
