Bill,
You don't have to change the sockets on your old lights. You get the bayonet LEDs from superbright LEDS. Your old sockets are fine!!!!! But do you know a place that sells the rubber gaskets that fit the glass globes. They have the bayonet LEDs in West Marine but they are asking $40.00 for them. Totally ridiculous. http://www.superbrightleds.com does it for $8.00 per light.
