I bought a name call: HID ynamic xenon system for 2002 WRX,
and I just installed it by myself,
it's very easy just plug in stuff, should I do something else like connect to the ground? because sometime when I turn on the HID and the right side will
not working, so I have to turn off the engine and try again, what I think is the
eletric can't go through well into right side of HID? so possible a battery problem? I just check my battery not really sure but the show something like
F 520 or stuff? in the sticker

 

Sorry but your post is a bit hard to read.
I've never heard of that name brand but I'll assume this is a "plug and play" setup where you just put the wires into the factory headlight plugs? If so that is your problem, you really can't do that and expect them to work reliably. HIDs require a high startup current when first turned on, and the factory switched ground circuitry cannot handle that much current, so when you turn the HIDs on there will be a big voltage drop on the ground side. The result of that is the HIDs may flicker and not turn on fully, or just cut out. Once they shut off the power to the ballasts has to be cycled to get them to turn on again.
The solution, assuming your hardware is not defective, is to connect the negative side of the ballasts directly to ground, and NOT to the factory low beam switched ground in the headlight plugs.
Now, in addition to all that is the matter of HIDs not being a good idea for use in the stock headlight housings because they were not designed for use with HID bulbs, but that's a whole 'nother issue.

 

sorry, becuase I am not really sure how to explain the problem, so kinda make you hard to read it..
but thanks for your answer, yeah, because I am using the stock headlight
I think that's why, so is there any way to solve it ?

 

Read my post more carefully, I told you how to solve it.

 

It may also be caused by the kit itself. Low quality kits tend to have issues. Also, make sure that the HID ballast is gounded itself.

 

Thanks ~~well, I don't know about this brand, I just know it's made in Japan and call HIDYNAMIC 8000K HID Xenon Conversion Kit, i bought it from Ebay~
so if I just leave it and don't solve it, sometime when it is flicker at begin start the engine or light go out, will it always damage the ballast or bulb?
sorry for keep asking Question~~just want to understand HID as well!!

 

Yes if you leave it alone the flickering/incomplete turn on will eventually damage the ballasts and bulbs, and can also cause problems with the wiring in your car due to the high current being drawn. Unfortunately as well many of the Asian-made HID components are not the best quality as per Alex's post.
If you directly ground the ballasts like I suggested it should make them work a lot better unless they are just plain defective.

 

I will try it with your suggestion, Thank you very much~~!!
