I only use full beam headlights at night on a motorway, with no traffic coming in front. Dipped headlights are normal running lights, unless you want to blind the poor guy coming towards you!

Quite right MOW, thanks for answering this. Smile

Also, it's a good idea to show courtesy to the drivers traveling in the same direction with you in front of you. I am sure you are switching to low beam when you are getting closer to them, just wanted to articulate this for others Smile

thanks darling...! Smile see, I DO know something about driving unlike what hubby thinks.... Rolling Eyes
And yes, I agree that this is more a matter of courtesy than anything else, and it's certainly not very nice when someone comes flashing full beam towards you...!

Oh yeah! And towards your back either, that was my point. But then they might want to see your back better, don't they? Wink

A few years ago when vehicle headlights in the USA were finally allowed to catch up with the rest of the world regarding headlight technology, I experienced some problems being blinded by oncoming lights which were not on high beam. I replaced the bulbs in my 2002 Mitsubishi Eclipse with Sylvania Silverstar Ultras. They performed as advertised. I was at first puzzled that I no longer experienced being blinded by oncoming lights. I did a little research and was surprised to learn that light waves of the same frequency colliding directly head on can actually cancel each other. Waves of similar frequency colliding nearly head on can produce a scattering effect. The factory headlights on my 2010 Kia produce the same effect. I almost never use my high beams.

I cannot believe I didn't see this thread before!

First, let's get rid of the term "high beam." It's not a "high" beam - it's a "full" beam, driving beam or main beam. This contributes that the main beam is the DEFAULT beam for night driving!

Anywhere from near sunset (or even in overcast weather) and to sunrise, even in roads with street lighting - use the full beam. Only dip the full beam if:

1. You might dazzle another road user or pedestrian (dazzle happens within 600 feet).

2. If the road is very well illumanted and you feel like the main beam isn't necessary.

Even in those situations, you can resort to occasional quick flashes of the full beam to illuminate the road without dazzling anyone.

Using the full beam gives you thrince the range, about twice the spread and about ten times more the more clearity in the lighted area. It can also make you more conspicious to other road users and even help light the road for THEM.

Single Carriageway
In a single carriageway, drive on the full beam and dip once an oncoming driver comes into view (or if you follow another driver closely). When the other driver is about to get past you - undip. Because of the angle, you will not dazzle the other driver, but you will avoid transitioning from the area illuminated by his lights into the darkness.

If you are driving on a dual-carriageway and on the right lane, you can undip even earlier (when your headlamps are about 45 degrees relative to the driver of the other car).

Right-handers
Keep the full beam on and dip before another driver (or the lights of the other car - if you cannot see the car itself) comes into the area lighted by your lamps across the bend. This method illuminates the bend for the other driver and alrets them to your presence.

Left-handers
In tight corners, keep to the far end of the lane and keep the full beam on. You should manage to make it across the entire turn without dipping (or dipping momentarily) and without dazzling another driver.

Astraist, Please no offense intended I admire your knowledge. Please realise that other people use other terminology. In the USA the common term is "Low Beam/High Beam". Low beams are aimed low. High beams are aimed high. It makes perfect sense to us. These terms are used in our state driving manuals and written driving tests.

Yep, I can confirm it - high/low beam is a proper term on this side of the pond. Nobody will understand you if you say "full beam". Smile

This actually reminds about even funnier situation. Both my former and later wives grew up in the places thousands miles away from the place I grew up. And with both we had a blank stare moments when something that was said did not register with the other side at all. Not many cases, but at least a handful of things had totally different names.

And this is the same country! I can imagine how many language differences are between English speaking countries scattered all over the globe. Smile

Thanks Misha. I had never heard the term "Full Beam" prior to this forum.

Me neither - but then I never lived in Israel, so this may be Israeli specific.

It's actually an English (i.e. British) term. The Israeli term, obviously in Hebrew, is "Road Beam", but the common expression is "high beam."

Sadly, people fail to use their high beams because of the risk of dazzling another driver and maybe cause they are afraid of what it might do to their gas consumption.

However, the high beams should be the DEFAULT light for night driving! Even many roads that are illuminated still offer poor visibilty. The high beams provide over thrince the range, as well as a bigger width and better clarity inside the luminated area. Also, the high beams can illuminate the road for other road users and en route alert them of your presence - before you get a chance at dazzling them.

I have trained many drivers who struggled with night driving and night vision, only to find the big shift in simply using the lights more inteligently in order to get a better view.

I even find myself using the high beams to flash into areas besides the road, like into woods or alleys that might conceal a hazard. The usefullness of the high beams at any driving enviornment other than broad daylight - including overcast weather, late evening nights and early morning hours - cannot be stressed enough!
