I got the cheap replacement bulbs in the mail, these, http://www.amazon.com/gp/product/B00...ilpage_o02_s00
Were super bright, but the angle of light was not sufficient for my bi colored nav light, these may work if you have separate red and green, for now I'll be sticking with the standard bulb.
Next I installed these, Amazon.com: ABN 2 PC 42-SMD T10 12V LED Replacement Light Bulbs T15 921 912 906 Extra Bri...: Automotive
in the anchor light. These are definitely good to go. Super bright and provide the required all around white light. I was concerned the light would be too blue or too yellow, but it is a brilliant white. These tests were done in the day time in direct sun, so we will have to wait for final results when I can get out at night. I tried to get pictures with my crap cellphone with no luck as the sun drowned out the light.
