Light bulbs in bow and tower docking lights?

[patryk]

Does anyone know what size bulb is used in the bow and tower diving lights? I'm going to want to switch them to LED when they arrive because I'm not a fan of halogen yellow. I want to guess they are probably A H3, but I don't have a boat here to check. I'd like to order them online before my boat arrives. Thanks!

Tower on the Alpha Z is a MR16

Thanks. What about the beam and wattage? I found them on Super Bright LEDs, but there are so many with different beam patterns and wattage. I am thinking about these, but they are 120 degree beam angle...

Then there are also these with a 30 degree beam

Wide beam would be a flood and narrow beam would be a spot. More wattage = brighter, but i doubt you will find an LED that would exceed the current draw of the bulbs coming out.
