more info about hid..
just to add info about hid kits....
this is only based on my experience and research made...
in regards to hid, all are from china except a few.. (matsushita,denso ballasts oem of nissan and toyota)- from japan, (osram, philips, hella, valeo (i think)- europe... in regards to prices, they are all based/depending on how the ballast look like, presentation, casing gimmicks.. i have tried them all.. same quality.. i have bought an hid kit which was 50$ nothing was wrong ever since, and some spent over hundreds, same quality.. plus they say lifetime warranty, which includes the price of sending a new pair in the end if ever your present ones stops working... sometimes its 50/50 chances either they go for a long time (2yrs-up) or for a while (3mos-6mos)
and remember, and its always good to keep a pair as a spare if ever it gets sent for warranty replacements while waiting for two weeks to get it sent and shipped back to you...
i have talked to a chinese supplier before, and my my, he has all the ballast and bulbs that are sold for a lower price.. cnlight has the best quality for chinese made.. more info about hid is in hidplanet.com you will learn a lot from there.. from veteran users to custom installers...
that chinese seller offered ballast wholesale are sold to me for 10-12$ each, and bulbs are 8-10$.. and you will actually see those ballasts and bulbs in ebay and some websites that sells them.. and it is sold for more than 50-60% of the original price.. explore aliexpress/alibaba(dot)com or madeinchina(dot)com and guaranteed you will see same design and and quality on the expensive kit that you have...
BTW i dont sell them business is not my thing...
good luck with modification...
