We replaced all of our lights
with LEDs last year. For the interior take a look at the Alpenglow overheads and reading lights
. We had tried numerous other bulb replacement LEDs but were never happy with the brightness or color. We put both types on Indigo and are really happy with Alpenglow's customer service and product quality.
For the exterior we used a Lopolight for the bow nav light and Bebi Electronic LEDs for the stern and anchor lights
. All are exceptionally bright and would recommend them.
