Is It Illegal To Drive With One Headlight FORD Focus Mk2 Hatchback (DA_, HCP, DP) (07.2004 - 09.2012)
- @john_s19.09.2025 07:32MemberIn the UK, driving with one headlight out is illegal as both headlights must be fully functional when driving at night or in conditions of poor visibility. The Highway Code and Road Vehicles Lighting Regulations require all lights to be in proper working order to ensure safety for you and other road users.
Key Points:
- Driving with a single defective headlight can result in a fine up to £1,000 and three penalty points on your driving license if stopped by the police or failing the MOT test.
- It is mandatory to use headlights from half an hour after sunset until half an hour before sunrise, or when visibility is seriously reduced.
- The MOT includes checks for headlight functionality and alignment; a failed light can cause an MOT failure.
- It’s important to replace a faulty headlight bulb immediately to avoid fines and safety risks.
Recommendations:
- Check your affected headlight bulb and replace it as soon as possible (usually straightforward on a 2008 Ford Focus).
- If unsure which bulb type to use, consult your owner’s manual or ask a professional.
- Have your headlights aligned during a routine service or MOT to ensure they meet legal beam pattern standards.
Driving with a full lighting system helps reduce glare for others and improves your own visibility, ensuring safer driving conditions for all.

Hey folks, I’m driving a 2008 Ford Focus and I’ve just noticed one of my headlights is out. Is it illegal to drive like this in the UK? Also, are there any specific penalties or issues I should know about? Thanks!
