My friend and I both have 37' boats (Tartan & C&C) . We purchased the OGM Tricolor lights
and have been duped. Both are not working properly. I actually used mine twice before failing. I suspected a bad wiring connection near the mast so I waited until this winter when the rig
was down to investigate. I have repeatedly contacted them leaving messages and emails. Note it wasn't the wiring!!! No reply ever... My friend had the same luck. Just try and call them before buying anything. They are scoundrels. He bought a light from Bebi electronics and I'm shopping for a replacement now. How can we tolerate a $500 light plus labor and it works twice. These guys should be ashamed of the junk they sell and the marine industry shoundn't tolerate it.
