would you trust those led lights

*********no I was just restating the fact***********************
One can make an LED light work with modification, I know because I have retrofit HID projectors/bulbs from a newer car into my older car. THE LIGHT WORKS the same as in the factory car the bulbs and projectors came from.

********but I will take you to task.**************
1.first you say "One can make an LED light work with modification..."
Sure, And 'one can launch a rocket to the moon'.
You statement is SOOO broad as to have no meaning.
To complete YOUR statement to be factual you would have to then say "IF MONEY WAS NO OBJECT."
The law of physics show that an LED buld has an ENTIRELY different hot spot that a halogen or HID. Since 'one' would have to creat a headlamp designed for an led bulb, one would need lots of money to computer design the angles to reflect the light CORRECTLY.
2. you then change topics in the middle of a compound sentence.
"I know because I have retrofit HID projectors/bulbs from a newer car into my older car."

you are talking about LED, and then you interject HID bulb that burns COMPLETELY different from a LED bulb....just for starters.e hid forum article on HID failing in a halogen headlamp.

Now the burden is on you to 'prove' that the led bulb buns at the exact same hot spot AND at the same point on the light spectrum.

(please refer to the link in the article I posted at HID planet)

So, "one can fly to the moon, because I drove to Dallas today". Doesnt make sense.
************************************************** *

There are cars from the factory ( Simply illuminating: Cadillac introduces its first all-LED headlight system | MLive.com )

*******************************Again, with money being no object I am sure you could retro the Caddy led light system......what.....$2,-3000? What would the Caddy system set you back? I owned the first mass produced HID headlamp system (02 Q45) each headlamp assembly was $1600 in 2003.**************************************

I am sure these could be retro fit as well.
******************Really???? Your 'sure'. I would suggest that it would be much more difficult than you think*************


There also many other bolt on LED options out in the form of fog lights and other auxiliary lights that come with their own housings. Ask a rally driver if those work or not.

The topic is NOT auxillary or fog lighting. The topic is 'plug and play' LED lights into a headlamp system.
I'll be glad to discuss AUXILLARY lighting in another thread.

Ok just so you agree that it can work and it can be done.

Oh and in a projector the HID and Halogen can interchange and put the hot spot in the same place. There are projectors from the factory that had both, can't tell if you knew that or not from your post. If you read through some more posts at hidplanet there is some more info about a few of these projectors if you want some more info on it.

These conversion leds have developed better but is there already someone using these like these H7?

I have these '50W' H11 LED lights in my fog lights.

I use them as DRL's.

They are not really 50W. They don't even give as much light as a 50W halogen H11 lamp would, though they come close.
They consume maybe 5W each.

Compared to the 55W halogens I had in my fog lights they are much less focused. Less light ahead, much more stray light.
That was just what I expected.
EDIT: this means of course that these LEDs are useless as fog lights. They emit light from several points way apart from each other. They are plainly impossible to use as low or high beams.
A LED low or high beam lamp would need to have all the light come from one single spot placed at and no larger than the position of the halogen glow spiral or HID spark chamber.
It is unlikely that there will ever be a LED that produces so much light from such a tiny area. any time soon.
OEM LED low/high beams use several LEDs each with their own lense or reflector.

As I swapped my (projector, HID approved) low beam halogens for HIDs I found that once running the lows adding the fogs was hardly noticeable.
I would never run my fog lights in fog without low beams on too so they were a bit dysfunctional.
Now, with the LEDs they are fine for DRL's.

That was funny!
The guy spends the entire time saying 'the led pictures are better in real life. My camera doesn't really show how well the led works'!!!

Or to translate:
' the scangauge doesn't really show the correct mileage ...'!

If you simply want more light try these. phillips H7 x-treme vision. They DO give more light. Own experiance. and top of the line halogen with good lifespan (can differ on some types. Had a citroen that chewed them up afther 10.000km. And in my polo they lasted 50.000km). not cheap but worth your money

As I look at the still picture comparison of the video that vekke posted, several things jump out.
1. The snow banks on the side w/led are toooooo bright. That is caused by glare (bad) and misdirected light (bad). The light rays are incorrectly bouncing inside the lens and not going where they are supposed to go. So your eyes are drawn to the space immediately infront oft the car and not down the road.
2. immediately infront of the car, the light is SOOOO bright that the white glare washes out the detail of the road. This is bad.
2. the distance light ends shorter and the road actually goes black BEFORE the silver sign dot at the end of the road.
3. PROPERLY designed housings w/ the CORRECT light source, project the light down the road. This keeps your night vision properly focused & adjusted for distance. The led is causing (incorrectly) your eyes to refocus on the space in front of the car, destroying your distant vision. Why is distant vision important.....BECAUSE THE CAR IS MOVING!
4. Because your eye is 'distracted' by the up close brightness, your eye muscles get tired quicker and driving no is unsafe.
5. The glare and brightness created by the incorrect bulb is now a visual distraction to the oncoming traffic.

Again, I cant repeat this enough.
1. 'light' has a spectrum, like a 1-10 scale. Each light source creates a different light hot spot.
2. Housings (the chrome thing that reflects the light source) are designed SPECIFICLY for the light source hat comes in it.
3. The light assembly AND the produced light are regulated to meet certain design characteristics. Unless the company making the alternative bulb has proof that the bulbs light passes the govt test, then it is NOT a correct replacement.

Just so we are clear.
Retro modding, retro fitting, retro: taking the ENTIRE lighting assembly (from a newer car) and 'modifing' the entire assembly so it installs in an older car. Leaving the proper light source in the proper housing.

Plug n play: installing inncorect light sources that 'fit' into an existing lens designed for another type of light source.

Light source: 1. hid, 2. led, 3. halogen Each have a diferent light spectrum and hot spot and are not enterchangeable despite 'fitting' at the base.

btw, if have posted at hidplanet in the past

Why does the set pictured in the first link come with ballasts? LEDs don't run on thousands of volts like HID does, so it would be unnecessary.

That said, I just replaced my halogens with a cheap $40 HID kit on Amazon, and I'm very happy with the results so far. The housing was already a projector style, so the beam is very well controlled, and nobody has flashed me for blinding them. I measured the energy use at 40 watts, which only saves me 15 watts, but it still gives me much more light.

Those led lights look much better to me in the video, however way too expensive at 160 bucks.
