How to use your car's high-beam headlights... properly

And how to avoid being dazzled by them.

HIGH-BEAMS OR full headlights are the really bright lights at the front of a car that are turned on by pushing or pulling the indicator stalk away from or towards you until it clicks. (On some newer cars, they’re automatically operated.)

Whenever your full-beam headlights are turned on a blue warning light shows on the dashboard.

High beams are used to increase visibility when it is dark. With dipped headlights you should be able to see about 30 metres (about 7 car lengths) ahead of you, however, with your high beams on you should be able to see 100 metres (about 25 car lengths) on an unlit road.

The RSA advises that you should always use full headlights when driving at night.

However, you should NEVER use your full headlights in the following situations:

  • in a built-up or special speed limit area where there is good street lighting
  • when stopped in traffic
  • when meeting oncoming traffic
  • when you see red lights of a vehicle in front of you
  • while parked temporarily
  • wherever they may cause annoyance or distraction for other road users

However, because high beams are so bright, you need to switch to your low beams within 150 metres of oncoming vehicles and within 60 metres of following a vehicle so you don’t blind the driver ahead of you.

It’s hard to guess such a precise distance, so use your common sense and basically switch off your car’s high beams as soon as you see the tail lights of a car in front of you or the headlights of a car approaching you.

If an oncoming vehicle has its high beams on and doesn’t turn them off, avoid being dazzled by the light by simply look toward the left at the edge of the road until they have passed and do not stare at their lights.

If the driver behind you does not dip their high beams while following you, flick the switch on your rear view mirror to night mode. If their lights are still too bright, turn the rearview mirror up toward the roof or pull over in a safe area and let them pass.

    Emm, who is the woman in this photo …

    ‘ A mock Presidential debate at Assumption Secondary School, Walkinstown. We think it’s mock. Image:’

    She looks nothing like the woman in any of the posters running for president… Is it Dana ?

    Looks like the real Seanie is gone to ground-was supposed to be on local radio today, but on mature reflection, decided against it.

    Yes it would Diarmuid. No I am not of fan of Davis. I am a fan of standards in photojournalism, however. If you think she looks well in the posters, then you need to address the focus issue you have with your eyes. Michael D will get my vote, as he is the only one fit to represent the Irish people.
