I have been doing a lot of research on HIDs and i am wondering the difference between these on ebay. The price is drastically different and I am wondering why. Is it just the brand or something more?

Here are the different options:

http://cgi.ebay.com/ebaymotors/BLUE-...spagenameZWDVW

http://cgi.ebay.com/ebaymotors/XENON...spagenameZWDVW

or

Thanks for your help!

 

Those are all bulbs, they just have a blue tint. I'd guess they also run at a very high wattage to make them brighter. These would probably burnt out in a couple months, as well as mess up your wires.

HID kits look like this.

 

Looks like you need to do some more research. As ELVATO said, those are just bulbs made to look blue.

A real HID kit will come with new bulbs (that look nothing like the stock ones) and a ballast for each bulb. Again, look at the link ELVATO posted, or check around the forums for HID Installation Instructions.

You need an H10 and H13 kit. H13 is the headlights, Bixenon if you want to keep your highs and low and just a regular kit if you want just the lows.

H10 = 9145
H13 = 9008

Don't get those blue bulbs, they suck compared to true HID.

 

H10 are the fogs?

 

Yes, H10 or 9145, both are the same.
