Lighting

Only obligatory (must have) lights are tested so if you have front fog lights or reversing lights that are not working don’t worry as they are not part of the test.

Front and rear position (side) lights. White at the front and red at the rear, don’t worry if they are broken this is not an automatic fail, just get some lens repair tape or even selotape for clear lenses, this will be assessed on security of tape, colour and light output (so not too much)

At least 50% of each lamp must be visible from the front or rear so if you have a cycle rack or tow bar that covers part of the light you will still be ok.

Near side is passenger side, nearest to the kerb. Off side is driver’s side.

Rear fog light is a must, but only one is necessary and from the centre to the off side. So if you have two fitted as standard and the near side is not working, good news it’is not needed.

You must have a tell tale inside the car that illuminates when the fog light is switched on.

Rear reflectors cannot be repaired with reflective tape, so these would need to be replaced.

Indicators must show the correct colour, sometimes on modern cars with clear lenses they have a bulb covered in orange plastic, over time with the heat this plastic peels off and starts to show white light which would become a failure. These bulbs can come in useful with a broken orange lens covered indicator that shows white light. Change your clear bulb for one of these orange covered bulbs; seal the lens with selotape to keep out the rain and then you will have yourself a pass.

Indicator tell-tale maybe audible or visual and must been seen from the driver’s seat. This may not be necessary if one or more indicator lights on each side can be seen from the driver’s seat. For example if you have indicators on your mirrors.

Head lamp bulbs are not obviously that easy to fit, there have been many occasions that these bulbs have been put in upside down or side ways. This will give an incorrect beam pattern which will reduce visibility for yourself and dazzle on coming road users. Before you carry out a bulb change pay particular attention to how the retaining clip holds the bulb in place, also how the bulb is located.

There are many choices for head lamp bulbs, here are the three most common with an explanation to.

Fit the flat edge of the bulb into the flat edge of the head lamp. The single pin points to the top. Similar to the centre bulb, but only two connectors.
