Pablo,The light covers on my H-26 are a 'three tab' insert type. Basically the lens cover has three small tabs around the ring that slide into three small slits in the fixture itself. I used a small screw driver to 'pop' the cover off - when one tab comes the others follow. Putting it on is pretty much the reverse - get at least one tab in and the 'smack' it home (well, not too hard, you know?)I don't have the exact light numbers on me, sorry. Take one out and take it with you (of course) and go to an autoparts store - they are the same kind of lights used in dashboards, etc. and a lot less expensive than West Marine's 'marine grade' bulbs. I couldn't see a difference in make/quality but you do have to watch the watts since the auto lights come in all varieties. Dave Crowleys/v Wind Dreamer
