I am seeking replacement light bulbs for the brass cabin light in the main saloon of my Sharki. The lamp is made by Poinsard. The bulb is a 12v 25w bayonet type with two contact points. The base is approximately .875" (22mm) and the bulb is approximately 1.25" (32mm)diameter. It is about 2 5/8" high overall. Writing on the bulb is: SPLENDOR 12V 25W AUSTRIA J4. I haven't been able to locate such a bulb locally and would appreciate any help. Thanks!
