should i buy it or is it just crap?

do a search for hid kit, you will find all the info u need

there are different opinions

i did and there is nothing on the just seller praising up there items :rant:

from what i've heard Philips Diamond Vision let out the same amount of light as the HID kits. They're $150 in a H7 bulb

And you get people saying this is illegal and so is the HID kit.

I get the Diamonds at much less, about $85.00

OK - Out of interest I decided to test a H7 hid kit in some one piece parabolic headlamps. The results were interesting, the beam quality was close to identical to that of a H7 halogen.

Only use these bulbs in single piece parabolics, the two piece have a different glare sheild and throw a lot of extra glare at oncoming drivers.

(I have some Hella 90mm highbeam modules that I am looking to use as driving lights that accept these H7 Hid bulbs VERY well)

I used a pretty decent kit to do the testing, with a 5000K bulb I had laying around (dont go any higher than this, 4300K is ideal, you will have less light than halogen).

If the bulb is secured properly (ie you need to either modify the standard H7 Halogen bulb holder to accept the HID bulb by hacking it up, or make a 4mm thick H7 base out of aluminium sheet or nylon) then it looks like this. A good kit will also use a decent bulb rebase, with a shortened return wire so it doesn't foul on the glare box.

Chinese made ballasts and bulbs have sketchy reliability too, and its still illegal (could result in your insurance being voided if your lights cause an accient).

Have a look at the pics and decide for yourself.

Comparison photo was taken at 14mm, F5, 1/60 sec at ISO400 with an Olympus E-300, no exposure compensation between a brand new Philips Vision Plus 55W H7 and a brand new 35W 5000K H7 Hid kit. Apologies for the bad photos, they didn't resize well :doubt:

what I understand from your post is that the HID kit *may* provide similar lighting to a normal halogen H7 in one piece parabolics, but you need to do some modification of the bulb base to get them to fit, and if you use the 4300k kit you *won't* get as much light as halogen...?

all that and it's illegal (unless certified, I assume?).

:nuts:

not really worth doing then, is it?

no 1 piece parras still suck...

test them out at night against a wall, there is still no defined cut off and there will be glare everywhere

4300k is the best any higher where the light turns blueish and the light decreases

Yerp. 3rd gen parabolics are very poor headlights. It doesn't matter what you stuff in them, you just wont get better light (unless you replace the optical elements etc).

You will get slightly more output* than halogen with 4300K, about line-ball with 5000K, and less as you go higher and rice-ier.

*higher output is not neccesarily good as it is all in the wrong place anyway, all you succeed in doing is blinding yourself at night with an incredibly intense forground that gives the illusion of better lighting.
