Lookig at the 2004 West Master Marine Catalog, on page 697, the side lights are either West 281147 and 268518, Perko No. 0955oP0CHR and 1264DP0CHR (They are sold in red/green sets and I can't recall which of those two sets is the right size), and the stern light is West 257162, Perk No. 0965DP0CHR. They are also available, I believe, from Defenders
They visually look the same, but the gasketing and the interior lamp design is improved over the original lights. And yes, they are bright shiny chrome.
