AlpenGlow was started by some folks that started out building their own lights, and now making them for commercial sale. Looks like some nice products. LED's are the way to go for many things, in my opinion. The low power draw, low maintenance and long lasting qualities are all important in the marine environment.

Saw a posting about a new line of LED lights by Tim Flanagan of Navagear. Looks like a nice line of lights.

I hadn't really looked at Perko before... neat looking supplier. They carry a wide range of boat supplies, lots of lighting and electrical, deck hardware, etc.
