so i bought some 6k 9004 HIDs awhile back, and they are great, but i was looking through the forum of the 9004 to 9007 conversion and it was saying that 9007s are so much brighter, so would 9007 HIDs be brighter than 9004 HIDs?
nope.
defitnaly not, it just means the sockets are different and the blubs are the same. I just installed 6000k hid’s
