I have a 92 sc300. I wanna get led bulbs for the lic plate. The new lexus use blue lights, correct? Do i need white or blue led bulbs? Or what size do i need like it know its 168 but do i need a 1 led bulb or can i go with a 5 led bulb, like what size bulb is best?

Also my fog lights are white. Where can i find 3000k NOT HID 1157 bulbs?

Lastly I am going to get 4300k hids. My headlights have 2 small light bulbs. One is burned out and i need to replace it. What size is this bulb and where can i find a white one?
