Note: In June of 2010, Aqua Signal changed the design of their fixtures. The new fixtures use bulbs with convex tips. If your fixture was made in Germany, then this is the correct replacement bulb. If your fixture was made in China, and was bought in 2010 or 2011, you may have either design. If you have convex tips, see the related replacement lamps below.
