Good morning All,

There has been a lot of chat lately about HID headlights and MOT requirements but has anyone HID'd their fog lights, they take the same H3 bulb as the main beam. Do fog lights also need washers and self levelling?

Just a thought.

All Hid's need self levelling and washers

How will you do that in fog lights?

How often is it foggy?...or do you drive around in good visibility with them on?

Thats illegal!! :wonder:

Also....Brighter white light is wrong for cutting through fog

You need a yellower bulb

I think it's pretty obvious they would be illegal, in the same way as the 100W bulbs they sell are for 'Offroad' use only.

Fitting self-levelling and washers wouldn't help as you'd be outside the construction and use regulations. Besides, HID foglamps don't sound like a very good idea actually as you want diffuse light in those conditions.

I'm pretty certain that the more yellow the light, the better it cuts through the fog and so it makes it easier to actually see and to be seen with in thick fog. HIDS obviously aren't anything like yellow, and so you just end up with a brighter whiter beam that's harder to see through fog with......unless of course you're one of those twonks who drive around with fogs on all the time??

Steady!

Ahhh Good to see everyone is angry on a Monday morning.

No I'm not one of those, I'm one of those who uses my fog lights when it improves visibility. It was just a thought, it stands to reason that as HID's are significantly better than standard halogens that they may be better for fogs too.

Nope, as others have said you need a less bright light bulb for useful use in the fog, this is why in really heavy fog it is beneficial to use just side lights (no dip beam) along with the fog lights, especially if you have xenon's this will reduce the glare off the fog.

+1 and heavy snow too it helps

If you want a good explanation why Yellow is better in Fog, have a read through this article. Daniel Stern Lighting - What is Selective-Yellow Light?

That is rather in depth!

they do pass an MOT if the light beam is correct and flick the correct way, and it will pass an mot with hid fogs as they dont test the direction of the light,

Dont listen to all these miserable SODS !

But some AN&L police man may take offence to them ,

Or those of us that drive in the countryside a lot and are sick of being blinded by numptys with HIDs in standard headlamps. Yes it's always nice to be able to see better yourself, but just think how much it will hurt when the other driver you're blinding crashes into you :p

very true, Pease take this into consideration !

i dont know of any one that has crashed from been blinded by HID's but i do know were you are coming from ,

It's usually a case of aiming the car and hoping there's no rocks/animals/umpalumpas in the road for the next 50yards while you can't see a thing usually a pretty scary moment, especially at 60mph+

i know what you mean i hate it when you see them on cars that have one light the is pointing to the sky !

good job my focus st has all the correct stuff lol

... in really heavy fog it is beneficial to use just side lights (no dip beam) along with the fog lights, especially if you have xenon's this will reduce the glare off the fog.

Unfortunately that is now illegal too - dipped headlights HAVE to be used in conditions of reduced visibility...

IMO the fogs on the VRS are not brilliant. My previous Astra's were far better. I think it's down to the shape of the lamp plus where it's located. I can't get any roadside definition or illumination off the VRS ones.

Strange, mine pick out the kerb edge and foreground really kinda well..

You can adjust them on the vertical axis.. maybe yours need adjusting? There's a screw that changes the reflector angle with in the lamp.
