...motivation...
I have the 2006+ projectors because it came w/ the vehicle, but if I didn't have it, I wouldn't bother getting them.
Because they are expensive, the projection isnt that great & the beam pattern isn't sharp.
I would do a retrofit. I've done a TSX projector retrofit on a Lexus SC300 before.
And I'm sure you want them to look OEM like nothing was done to it...I'm the exact way!!
I included some links for you to check out...
