where do u get a HID kit?
what does it look like at nite?
how does it look installed? Do u you have a big ugly box on the dash or does it look factory?
How much does it cost?
does it work with other vehicles like the Avalon?
You can get them from ebay, online stores, retailers or you can check the For sale section like what mark said
It makes a huge difference compared to your stock halogens, but depends on what kelvin rating.
12,000k purple
10,000k pinkest white
8,000k blue
6,000k bluish green
5300k white/yellow
4300k white
3000k yellow
the higher the rating the lower the light output. basically the 12000k is a little brighter then stock. Totally defeats the purpose of getting HIDs IMO. It just looks cool. The best light output would be 4300k.
It costs from $250-500 depending on brand and application
And yes it will fit all vechicles. its simply plug and play.
