Brightness/ alignment of new cars/ LEDS head lamps

No yellow beams are lethal, I have used yellow lenses/bulbs in old cars before trying stock halogen bulbs and again with retro fitted HID's/projectors, they're fine until there's fog/smoke/mist, then all you see is a white solid cloud infront of you, higher kelvin doesn't do this, that's why they don't use yellow.

Another scary thing is, things like deers/rabbits are harder to notice with yellow, I found they tend to blend into foresty/grassy/bank areas more under yellow light due to having a colour tint over everything you see, this in the rain makes things very dangerous, with white lights you obviously spot a grey/brown animal as there's no colour tinting everything you see.

High Kelvin does do that. It's a smaller wavelength so it doesn't penetrate as well. The closer you get to blue the more it scatters.

Specific models made in china for the chinese market.................. however all JLR cars are made in the UK or EU for our market AFAIK (jonnycoupe will correct me if i am wrong i am sure)

not my stats but a quick google shows this stolen shamelessly from speakev forum

Whitley - Powertrain engineering and Global Corporate ...
Gaydon - Principal design and engineering
Solihull - Builds F-PACE, Range Rover, Range Rover Sport, Range Rover Velar.
Manchester - Software and IT
Castle Bromwich - XF, XJ, F-TYPE and XE
Wolverhampton - Petrol and Diesel engine plant
Halewood - Evoque, Discovery Sport

Outside the UK but in the EU:

Shannon - Software Engineering: automated driving, electrical architecture, next-generation telematics, cyber security, cloud services and benchmarking.
Budapest - New office. EU Supply chain managment, design.
Nitra, Slovakia - Defender and Discovery.

Graz, Austria - Magna Steyr builds the i-Pace under contract.


but yes with chinese factories for the chinese market - which seems sesnible to me.

BUT all that said...... since when was built in China a recipie for disaster anyway? loads of premuim cars (and other products) are built over there - often to a higher standard than western equivalents.

also with a PS of I am not defending JLR build quality or their customer service at all...... that is not the point of my post...... I guess i just get a bit tired of the whole "built in china = crap " stereotype

I was talking about Lucas electrical components. An OE brand. They was always **** and appeared on a lot of British cars. Then supposedly got worse when they became Chinese made. They are famous for being bad.

They can make the car where they like, but if they are using cheapo components it won't help. We all see how unreliable Range Rovers are, especially electrical stuff.

A very debated subject and the science usually comes up against yellow lights.

I can say from doing a lot of driving at night though with the Philips Xtreme Vision on my truck which are near day light temperature on main beams but have a yellow hue on dipped, originally were on cheap yellowish halogens when I got it and other vehicles with more modern white light for both you don't want yellow for main beams - stuff like animals are definitely better picked out by white light, but the slight yellow hue of the Philips definitely is nicer on dipped for making out detail in fog and rain where the white often just blooms - the same doesn't really hold up for main beams though (if you get the same level of light output the results are similar).

Yep, animal visability is lethal with yellow.

Have you ever tried Osram Nightbreakers? They're a decent shout too, never used the Philips but heard good things about them.

Don't find the Osrams quite as good - Philips do some kind of colour biasing which makes things stand out a little better - though the Osrams are whiter.

Yeah I always heard the Philips were better but more expensive and died quicker, I imagine burning brighter? I've had hit or miss experiences with Osrams, depends on the bulb type, some are no better than normal bulbs despite the wild claims on the packet.
 
so, are they still handed ?
think about it - UK you have a kick up on car near-side - and those leds would have to be off in europe - so the lights wouldn't be as good

Can’t speak for other cars but on my E Class, you can set which side of the road you drive in the light settings
 
I couldn't beat them so I joined them and made sure the car I've just ordered has full led auto headlights
 
There can't be many new cars on sale today that don't have auto headlights or LED headlights.
Plenty if you're only looking at the smaller cars.
You ask them to make sure they aren't adjusted properly so you blind everyone constantly?
I'll make sure they're wonkier than a cross eyed baby before I drive it away
 
Here is the thing though - can you even 'adjust' these modern lights?

There are adjustments on the back to align them. They "self level" but only to maintain what they have been set to.

The self leveling stuff and the motors inside them can die ofc, as well as the LEDs. and then it's bend over time because these lamps are sealed units can cost thousands each. Yay for progress...

They have individual segments to do what they need to, they area of a headlamp nice is far in excess of what’s needed for lighting so they are not the constraint they used to be.

Think about what? Less LED than possible cos you want a portable sun in each lamp?

this should never have been allowed to be honest. as much as I like my headlights...... they need to be a serviceable part within reason. a few hundred quid, that stings but it's doable in a high end car. but someone posted earlier they had to pay thousands and that is nuts

They could easily make the bulbs changeable, but that's bad for business

Manufacturers saving money by not having to have someone fit bulbs on the assembly line probably :/

Tell me you don’t know how LED lights work without telling me you haven’t got a clue.
