Why aren't the car makers going with led lights ? I was given a led lenser for helping someone out with a central heating boiler, it has amazing light, uses very little power and is fairly cheap.
The beam pattern from a correctly fitted hid is identical to a halogen. The kelvin is different, and the brightness higher.
Anything remotely recent I.e 80's onwards has a cut off beam preventing blinding light.
The issue comes when Dave puts said hids in his badly aligned headlights ( probably the reason he decided to upgrade them in the first place) and leaves it at that.
Headlight beam testing is done by sn "independant" company funded through a collaboration of car manufacturers.
Additionally car manufacturers who have sold hid systems did not initially provide special light units, or auto levelling.
The eu decided on e marking for hid on the light, because otherwise an old car on self levelling suspension with a headlight wash system would comply.
And how much tax and revenue do the automotive industry and government stand to loose?
£500 option vs £30 eBay... You do the maths.
The new Ford 150 will come out with LED lights. It's the future. My 7 x cree led torch is unbelievably powerful, much more so than the headlights in my '01 Volvo V70 or my motorbike.There is quite a lot of heat to move away, it occurs at the LED junction, and LEDs are still in their infancy.

Andystobbs. Can't seem to quote on phone ;(
They just need to be correctly seated, and aligned. Some hids aren't a direct replacement as they are longer. The actual arc takes place in the same position as the previous filament .
I believe seat are using LEDs for everything now. However they become increasingly inefficient and bound by temperature as you increase the output.
quote. u can get replacement led bulbs for 400w sodium high and lowbay fittings. the thing is though they have a small fan that permanently runs to keep them cool and there expensive so there size is limited without cooling
