					<description>&amp;gt; How I loathe US headlight laws and how they 
&amp;gt; affect me in Canada.

And here I was thinking how unnecessarily bright US headlights have gotten these last few years, to the point where you never actually need to turn on your high-beams even on unlit country roads.  Just the regular beams, if your car was made any time in the last two and a half decades or so since the popularization of halogens, are enough that you can see objects *in color* at a quarter of a mile (provided the road is sufficiently straight and flat that you have line-of-sight down the road to anything that distant, which in some parts of the US goes without saying, and in other areas would be rather unusual).

IMO, if you think US headlights are too dim, you probably should make an appointment with an ophthalmologist and get yourself checked for cataracts.

&amp;gt; those blue eye-searing lights

Those things *definitely* ought to be illegal for low-beams.  (For high-beams it isn't as much of a problem, provided the law against shining the high-beams into oncoming traffic is enforced.  You seldom need high beams in central Ohio, because there's almost always oncoming traffic, but in places like northern Indiana you do use the high beams sometimes, and a bit of extra brightness doesn't really hurt anything there, even if it isn't strictly necessary.)</description>

					<description>A lot of the worst HID headlights are cheap retrofit kits, which aren't aimed properly. A proper HID headlamp may look a bit weird - classically, that freaky blue flash at certain angles that makes your &quot;Aaah! A cop car!&quot; neurons fire - but it shouldn't be any more annoying for other drivers than an old-fashioned filament bulb. But lots of people have mis-installed HID lamps that're too bright at other angles.

(Just setting them up for a plain symmetric beam is actually likely to be illegal; low-beam headlights are actually meant to give an &lt;b&gt;asymmetrical&lt;/b&gt; beam, illuminating less of the side of the road with oncoming traffic. So they favour the left, here in Australia; the right, in the USA. This is one of the several things that can bite you if you insist on driving a left-hand-drive vehicle in a right-hand-drive country, or vice versa.)

The popularity of SUVs is another problem, here; if you're not driving a vehicle that's just as tall as they are, your eyes will probably be below their headlights, which makes glare an issue again.</description>

					<description>Hmmm.. there are plenty of vehicles with HID beams here (California) - those blue eye-searing lights are a menace I tell you.  

That being said I've been trying to find a retrofit HID bulb for my motorcycle - where I actually want to cause oncoming drivers some annoyance.  An annoyed driver is one who's aware of you after all.  I've already wired up 2-watt leds (8 of em) into my taillight and rigged em to flash from normal to &quot;holy cow, what the hell was that?!?!&quot; for the first 10 seconds after I engage the brakes.  I wish I could leave 'em on super bright but the cops frown upon tail lights brighter than many headlights.  Ah well.</description>

					<description>Does this mean North American BMW X5's don't have unbearably bright HID headlights? And the sporty merc's aren't blinding all oncoming traffic. Does it mean even fools in regular euro car can't drive day and night in North America with their foglights shining all over the place?

If so then count your blessing....unless you are a tosser in an X5, in which just ef-orf with your rediculous low beams.</description>

					<description>Changes, Probably - that's gonna be the next thing up. Part of the problem is the yellowed polycarbonate lenses.

evilspoons, the Mystake (Mondeo) is a '97... hmmmm.</description>

					<description>Our roads are lit enough that I find myself forgetting about high-beams completely. I only ever use them to signal to incoming cars when I see a speed trap... which is technically illegal, but if they ever fine me for that I'll put a frame around the slip and set it on my wall for all to see.
(Lest you think that I'm a speed demon, there are places around here where limits are absolutely ridiculous; it's those I have a problem with, not the traps on the highway.)

FuzzyPlushroom: can't you replace your bulbs with better ones while staying inside the legal limit?</description>

					<description>How I loathe US headlight laws and how they affect me in Canada. I wish we followed the Commonwealth and had REAL headlights around here! My old '87 Volvo 740 is suffering from absolutely horrible high beams and pretty bad low beams thanks to the Americans dictating it had to have quad rectangular sealed-beam bulbs instead of the excellent European E-Code reflectors. 

I installed sealed-beam to H4 conversion bulbs and have rectified some of the absurdly bad high beam problem, but the beam pattern of these conversion units is lousy and installing brighter bulbs will just mean a larger lousy mess.

Incidentally, this H1 bulb you speak of (from 1962) only became legal in the United States (and therefore Canada) in &lt;strong&gt;1997&lt;/strong&gt;.</description>

					<description>Maybe they mean low-beam headlamps? I know my car (an American-market Mondeo) has some of the worst low-beams possible - I could do better if I JB-Welded a pair of cop-issue six-D-cell incandescent Maglites on my front fenders.</description>

					<description>I think their claim of &quot;7 times as strong as a headlight&quot; is not a stretch. Remember that they are in the US, and our headlights are limited by law and are weaker than other parts of the world. The high beam on many current US cars is only 1200 lumens (an 9004/HB1 lamp). There are others (9007/HB5) with 1350 lumens.</description>

					<description>The big question is, of course, why go to all the trouble and expense of a multi-LED-multi-die contraption when a HID will do the job just fine for less money.
I love LEDs and pride myself on not having a single incandescent flashlight (much like you, I seem to have a growing collection), but if I had to get a Serious Spotlight I'd get a HID.</description>
