I would recommend two 194 5-5050 SMD bulbs for the license, and one 12-SMD board for the trunk.
We are currently looking to make this kit, it is requested all the time.
It's really worthless to switch your headlight bulbs unless you're going HID. A new pair of halogen bulbs will cost around $50 and still not be white or bright. New HIDs are just $80.
LED bulbs are brighter, whiter, and use less power.
What?
