Re: Dangers of LED navigation lights
I use LED lights exclusively for a number of reasons. They are more efficient and more reliable. But mostly they also cut through haze more effectively. There is an unmistakable spookiness to LED lights if you know what I'm trying to say. Maybe it's their phase or something. But I consider them far more visible than incandescent bulbs which are also more likely to blend in with back ground lights.
As far as avoiding collisions, hopefully everyone is using every available means than just looking for a light. And no one should be careening through an anchorage at night without a proper lookout on the bow.
At anchor I usually keep my spreader lights on all night too as the party doesn't stop until 6 in the morning.
