USCG Approved LED Anchor Light
I bought an Orca Green Marine (OGM) all-round white anchor light that I installed last Spring. It's great. Has a photo-diode to turn it on and off (and they claim if the diode switch fails, it'll stay "on"), and draws next to nothing in current. It is very bright, and I can easily spot my own boat from a distance by the slightly bluish light.They advertise it as USCG approved.At the following site you can buy it with the bracket, for the same price as without the bracket from OGM.(I have no affiliation with either of them, other than being a happy customer.)Craig
