Hey boat owners! If you need to replace the navigation lens on your SeaChoice 0515 marine light, this is the exact replacement you're looking for. This 112 degree red and green lens features highly polished stainless steel side light construction that's built to handle marine environments. The bulb can be replaced from inside the boat, which makes maintenance so much easier. Measuring 7-3/4 inches long by 2-1/2 inches high by 2-3/4 inches deep (that's about 19.69cm x 6.99cm x 6.99cm for our metric friends), this lens is designed to fit perfectly on SeaChoice 05161 and SCP05161 models. The red and green coloring provides that essential port and starboard navigation signaling that keeps you safe on the water after dark. Made from durable materials that can withstand sun, saltwater, and the general wear and tear of marine use. Installation is straightforward if you're handy with boat maintenance. Seriously, if your current navigation lens is cracked, faded, or just not working properly, this direct replacement delivers that factory-fit performance without the hassle of replacing the entire light assembly. It's one of those essential boating maintenance items that ensures you stay safe and legal when operating after sunset.
