    This is the brightest one I've found and lights up the whole boat.

    A bright and Quiet LED

    Using this for the steaming light replacement in an Aqua Signal 40. Very bright and zero rf noise in VHF. The VHF antenna is less than a foot from the steaming and anchor light.

    Great running lights

    Lights are bright, fit great and priced very well. One of the bases appeared slightly damaged but it still works so I installed it and so far no problems.
