Hello , i've bought some 6000k quality bi-xenon for my civic 01 . They are ok but the only probleme is that there's almost no light close the car on the road ... I don't know if you understand . On a wall you can see almost no light at the bottom .

obviously it was not "quality" enough. lol

but on a serious note

any time u stick a "hit kit" into a non HID application (like ur stock headlights) you will run the risk of producing improper light reflection (hence you dont get any light near the bottom of the beam pattern.

here is the longer explanation if u are interested in the dynamics of it.


In a perfect world, a halogen h4 and a hid H7 would be identical (obviously except for one burns and filament and the other ignites a xenon gas)

In that perfect world, if you plug a hid h4 bulb in a halogen H4 socket, you light output would be exactly the same as oem. Meaning ur cut-off would he the same, your beam pattern would be the same, and the only thing that changes is the amount of light output (lumens)

However, we dont live in a perfect world.

As a result, the hid bulb actually replicates an H4 socket (base) in order to fit in the socket. So it's safe to say the aftermarket companies just reconstruct a generic hid bulb with different bases (h1, h7, h4, 9005, 9006, etc)

(This is the key to ur question)
So as a result, the filament (part where it lights up) POSITION of the halogen H4 and the aftermarket hid are now the same

and keep in mind the stock reflector of the halogen H4 bulb is VERY specific on the reflection angles, etc...

So if the filament/arc is miss aligned forward a little bit on the hid H4 bulb, it throws the reflection point off when the light hits the reflector, it goes ape **** and flies in unintended directions (and this is what causes glare).

i should add:

fast forward to 2011, most of the aftermarket HID bulbs are now made much much better than they were 5 years ago.

the arc position of most aftermarket bulbs are fairly close to the halogen H4.... ive seen a few really good ones outputs from a stock reflector and ive seen TONS of crappy ones (glare)

The first set of bulb i had for the car was ok ( 8000k ) . But I've changed for 6000k and it does that . I have a glare shild and the cutoff is pretty good .

You probably got a lower quality bulb when you switched to the 6k


Having a glare shield has nothing to do with the direction of the refractions of the light

The focal point on these bulb is better than normal one ...

 
Rep Power: 352

obviously not if u are not getting the lower foreground light.

you asked the quest, and i answered it.

if u feel these newer bulbs have a better focal point then great!

i get what hes saying...when he switched bulbs the light is more focused forwards than scattered downwards. i had this same problem when i got my hids...but i got some foglights with 10000k hids and its MUCH better.

ahah yep there you go . Maybe If I buy some 3000k hid for my fog it will be ok ?
