Well, you SURE don't want to get the OEM from Toyota. The whole bolt in assy was $250.
The lenses are removeable to change the "common" H3 halogen bulb, $2-3 from anywhere.
The body parts guide I have gives a part # for both left and right lenses, but I don't know if can still get them from Dealer.
Please read and follow the directions in....

I could have given you the part #'s had I known exactly what car you have.
