- Two headlights and two white sidelights at the front of the vehicle.
- Four amber direction indicator lights - two at the front and two at the back of the vehicle.
- Four red lights at the back of the vehicle - two tail lights and two brake lights - and two red reflectors.
- One or two white reversing lights at the back of the vehicle.
- Number plate lighting.
Daytime Running LightsSince February 2011 all cars manufactured in the EU have been fitted with DRLs (Daytime Running Lights). DRLs automatically omit light from the front of the vehicle once it starts moving. The white lights increase visibility in the daytime and improve road safety. They should not be relied upon at night-time or during lighting-up hours as they do not emit enough light. If your vehicle was built before 2011 and doesn’t have DRLs fitted, the RSA recommends that you use dipped headlights in daylight hours.
Full headlights should be used when driving at night, except in the following circumstances. In a built-up or residential area with good street lighting, when driving behind another vehicle (i.e. you can see their red lights ahead), when stopped in traffic, when meeting an oncoming vehicle, in dense fog, heavy rain or snowfall and wherever they may distract or disrupt other road users eg. cyclists or pedestrians. In the above cases, use dipped headlights. These should also be used at the beginning and end of lighting-up hours - that is, just after sunset and just before sunrise - and during daylight hours if your car isn’t fitted with daytime running lights.
No headlights should be used while a car is parked. Parked cars should only light up with parking lights or side lights.
Fog LightsFog lights are commonly misused by motorists. As the name suggests, they should only be used in dense fog or falling snow and you must switch them off when visibility improves. It’s an offence to use fog lights in clear conditions as they can dazzle other drivers. The RSA states that you should only use fog lights if your visibility is less than 100 metres - i.e. you can’t see approx. 25 car lengths ahead of you. Fog lights are best used with dipped headlights. When visibility is significantly reduced, it’s also a good idea to use your foot brake to slow down, so that your brake lights can alert the driver behind you.
Hazard Warning Lights
There are two main instances when hazard warning lights should be used. This includes if your car is stationary and obstructing traffic in some way or to warn a driver travelling behind you of an obstruction or hazard up ahead. Do not use hazard lights as an excuse for illegal parking.
We’ve all seen the driver that indicates at the last second before making a turn - don’t let that be you! Every time you change the direction of your vehicle, you must signify this with your indicator lights. Use indicators in good time, so that other road users can react - and don’t forget to turn them off after you’ve made your manoeuvre. Also keep in mind that putting on your indicator doesn’t give you the right of way: you must wait until there is a safe gap in traffic to make a turn or a change lanes.
