Attwood 2-Mile  LED Articulating All-Round Light
Attwood's Anti-Glare Lights are a great improvement – they focus light at the horizon and above, not in the pilot's eyes. The bottom aperture reduces glare at 7.5° below horizontal. Above horizontal, the continuous arc of light makes the boat more visible in rolling seas and to taller craft.  The patented Articulating Head adjusts from 15° forward to 15° aft. Just align to the horizon and tighten the adjustment screw!
