Headlamp height

[Matty F]

While there may be regulations for the height of tail lights etc, that really doesn't matter at all. The height of headlamps however is crucial. i.e. the height from the road to the middle of the headlamp. Granted that the headlamp should point downwards to some extent, but if it's incredibly high, say on a truck behind a car, if the headlamp is the same height or higher than a car's interior rear vision mirror, the driver will be blinded by the light. My rear vision mirror in a quality British car is 1100mm high (around

43"). Why on earth are headlamps allowed to be higher than 1100mm, anywhere in the world? Is there any conceivable vehicle used on a public road that cannot have its headlamps lower than 1100mm? Please give reasons.

Tractors with loaders on the front.

Tailgating me at night at 100kph? I don't think so.

[The Other Mike]

It's not unusual your regs could be the same as the UK where the limits are 500 - 1200mm. It's often the case that 'styling' considerations override the retinas of other road users.

My 15 year old BMW has an auto dimming rear mirror. Ace.

The first time I bought a car with one of these I thought "Oh, yeah?"

But actually they are, as Dave says, ace.

[Andy Burns]

Agreed, my last two cars had diming rear mirror, current car has dimming door mirrors too.

[Jethro]

Ah, but does it auto dim the side mirrors ?

[Clive George]

One of those tractors used for working over fields of tall-growing stuff?

[Jules Richardson]

New BMWs come with a built-in feature to dim the driver ;-)

[The Natural Philosopher]

Those normally have roof lamps for actual off road work.

I believe it is illegal to use *working lights* for road use.

Aren't BMW drivers already dim?

Not any more. Audi has taken that crown.

Those who make comments like this are best to state which makes they drive. So we can all have a good laugh...

My car has one, I but I don't use it much for the same reason that I wouldn't wear tinted spectacles for night driving. Yes it's more comfortable when someone behind dazzles you, but dimming the mirror might render that unlit bicycle about to undertake you invisable.

I can switch it off on this vehicle, I had to resort to bluetack in the sensor on the last one.

[Dave Plowman (News)]

Not the same thing. 'Tinted specs' would reduce your vision regardless of the ambient light. The mirror reacts to bright lights falling on it. And if those are dazzling you, you'll not see a less bright light source in it. And in any case, door mirrors are more use for bicycles.

you invisable.

on the last one.

Mine's all manual. But the choice is between not seeing anything at all, because the top of the beam of the 4x4 behind is shining right in my eyes, or having restricted rear vision.

The wing mirrors aren't as bad as they are convex, so the light is dimmer. And that's where I see the bike.
