Car Lights Law

Driving convictions, penalty points and fines are easily obtained if you don’t keep a careful check of your car.

This is especially crucial to new drivers who are still within the two years from passing the driving test and can only receive a maximum of six points to lose their licence.

It’s important that all lights on your car are kept clean and in good working condition to not only remain within the law and to avoid penalty points and fines, but to remain safe yourself and for other road users and pedestrians.

Detailed below are frequent mistakes made especially by new and young drivers in terms of car lighting, the safety implications involved, plus the potential fines and penalty points involved with defective or inappropriate car lighting.

    is there a law regarding the use of colour changing side lights as I have seen many a car with side lights that change colour

  2. Generally it should be white / amber at the front and red / amber at the rear, though there are some exceptions:

    Side lights that actually change colour would be highly distracting and confusing to other road users. I can’t imagine that they would be legal.

    I’m yet to fix the earth fault which causes my rear left light to go out when my break lights are on. Is this illegal?

  4. Hello Emily-rose,
    It is a minor defect, so I would think it would have to be pretty harsh for a police officer to issue any form of fixed penalty notice. They may well stop you, though it’s more likely you’ll be issued a VDRS, or Vehicle Defect Rectification Scheme which entitles you to 14 days in which to get the defective light fixed and within this time, you’ll need to provide evidence of its repair. VDRS are typically issued for minor defects.

    Is there a requirement that a car that has broken down on the freeway while it is dark out MUST use their flashers to warn other drivers? Can’t seem to find a vehicle code section directly on point.

  6. Hello Kelsey,
    In the UK you should use hazard warning lights and if it’s dark, then also use side lights if possible. There’s no specific law for this. The Highway Code generally consists of advice to follow which is defined by ‘should’. Regulations come into place where the word ‘must’ is used.

    Is it a legal requirement to have front sidelights in working order?

  8. Hi Alan,

    The Highway Code (Lighting Requirements) states:

    You must ensure all sidelights and rear registration plate lights are lit between sunset and sunrise.
