Aqua Signal Series 25 Classic Navigation Lights Reviews:
Product good, picture...not so much!
My masthead (steaming) light was knocked of during the mast raising. As it was the original ('82) and it was pretty beat anyway, I told the yard I would take care of it myself. West Marine sent me what I ordered, but it was not what I expected, didn't match the picture (continueing complaint I have with WM). But the new part fit into my existing combination steaming/foredeck light housing just fine. The bulb wasn't the same, but I had spares that worked!
