For the IS350 with factory xenons is there any bulbs we can replace them with !!! 6000k,8000k ??? Thanks

 

you can replace them with anything color as long as they're d4s bulbs. The only one I know of is the philips 5800K bulbs.

One member got them and he didn't notice much of a change in color but someone else got a pair and it was noticeably more blue/purple IIRC.

 

Why does only philips have the bulbs?

Arent HID's common??

 

Check out XenonValot.com. They got some 6000K D4S bulbs. Made in Japan. NOT Philips brand.

So far, All aftermarket D4S I have been seeing is from Japan.

PIAA also has some 5500K D4S HID

 

d2s and d2r HID's are very common. The IS uses a d4s bulb, which is not that common.

xenonvalot is the only place I know that carries aftermarket d4s bulbs. I know philips makes 5800 K bulbs but have never seen one available.
