You tried the super white leds? O and you know what worked for me, taking the driving lights out! =) Honestly I don't know if you want to go this route buttttt the ddm halos from the rpm store match the 4500's perfectly (that's the setup i have only with 35 w), so if you pull the driving light out throw in the halos you will have an almost perfect match. if you want i can post some pics just let me know.
That does seem pretty close. If you get a chance and can throw some night pics up thatd help. Did you have the 4500 55w or 35w? Cause they should look a little different if you have the 35w, only thing im concerned about.
