i replace all of my worn out gold ones last year, the one in the grille is held on by one screw and one tab on each side, the "lexus" on the trunk has 4 or 5 pins i believe, the "L" has pins also, and the "ls400" is held on with just tape. for the front L, rear L, "lexus" and "ls400" costed me 150 from dealer, but i think you can get them off of ebay for much cheaper (just read the description carefully)
