Hi

Some may find the below article of interest

http://www.ledsmagazine.com/articles/2005/06/leds-are-safe-fact-or-fiction.html



Certainly should be considered if looking into high powered leds[ such as torchs']

All of the quality LED torches that I have do state "not to shine in eyes" or something similar.

Publishing an article in a relevant trade magazine is designed to protect the manufacturer/dealer from any idiot who shines the lamp/torch into his own or other peoples eyes.
It probably gives them an "out" should any hi profile law firm decide to try it on.

As an aside, I can remember as a child being old not to shine any torch into my own or anyone else's eyes. That was in the days of incandescent globes and a couple of D or C cells powering the torches available then.

I'm sure there are other 70+ old's who can remember the parents saying just that to them.

Disco.

I sleep with a high powered torch (4000 lumens) at my bedside exactly for this purpose.
Should any socially deprived feral get into my house at night – this is my weapon.

Precisely why the "tactical flashlights" with burst mode are so popular in USA security circles.

Bright light and eyes have never mixed.
Thought it was obvious.

Who can I sue for all the welding flashes I've got over the years (well, decades, actually)?? LOL

Mind you, I don't understand how those bloody projector headlamps, as fitted to a lot of high-performance and European vehicles, ever got approved?
They bounce over a bump and you get the equivalent of welder flash from them.

They are the worst thing I think I've ever encountered (apart from the blokes with 8 Cibie Super Oscars or 6 HID spots who think it's fun to give you high beam for 30 secs to teach you a lesson for being .002 seconds slow on dipping your lights).

I'm full of agreement with these sentiments!

Also fail to understand why DRLs are permitted to remain on once teh mains are lighted. Definitionally, I'd expect that when a driver switches on the "night time" lights, the "daytime" lights would not be required. Is that reasonable?

By definition, DRL must switch off when any other type of light is activated. If they stay on, my educated guess would be they fall into the category of fog lights.

Nope. My factory DRL's come on automatically after the engine starts, and switch off the same when ignition is switched off. They can't be overridden.

Doesn't matter whether the headlights are on or off.

Therefore I suspect your definition isn't quite right, Tim. The car has fogs as well, but I rarely use them. They switch off automatically whenever the headlights are on.

But getting back on the topic, my LED torch has both a warning etched into the case and in the owner's booklet.

DRL's either have to switch off or DIM once headlights are turned on.

It will only be a short amount of time before the adr's will require all new vehicles to be fitted with them. Europe has had this since 2012.

Oldtracks post is a good one in reminding us all not to look at the light emitted from led's.

I failed to specify that it is the case in NSW, I don't know what other states have. You will find it under the Road Transport (Vehicle Registration) Act.

Division 4 Daytime running lights

94 Daytime running lights

(1) A pair of daytime running lights may be fitted to a motor vehicle.

(2) A pair of daytime running lights fitted to a vehicle with 4 or more wheels must be fitted with the centre of each light:

(a) at least 600 millimetres from the centre of the other light, and

(b) not over 510 millimetres from the nearer side of the vehicle.

(3) However, a pair of daytime running lights fitted to a motor vehicle under 1300 millimetres wide may be fitted with the centre of each light not under 400 millimetres from the centre of the other light.

Location of daytime running lights on a vehicle

(4) When on, a daytime running light must:

(a) show a white or yellow light visible from the front of the vehicle, and

(b) not use over 25 watts power.

Note. The third edition ADRs only allow white daytime running lights.

(5) Daytime running lights must be wired so they are off when a headlight, except a headlight being used as a flashing signal, is on.

(6) For subclause (3), the width of a vehicle is measured disregarding any anti-skid device mounted on wheels, central tyre inflation systems, lights, mirrors, reflectors, signalling devices and tyre pressure gauges.

My car has its DRL's in the headlights, as well as the LED turn indicators. That explains why the same-side DRL switches off when a turn indicator is on.
