[Rhodes22-list] Replacing the wire in the mast

[cjlowe at sssnet.com]

Mike is correct about connecting LEDs in reverse polarity. Thanks for your
input.
I made my anchor light and a steaming/deck light with LEDs from Bebi
electronics,and they said that their's will stand up to the task of
reverse polarity. So far (4 years) their right.They explain about it on
their site.  Just google Bebi Electronics. They have a couple of neat dome
lights.I have 5 of their units onboard and I really like them.
Bottom line,don't use reverse polarity on LED lights without blocking
diodes,unless you know for sure the lights are made for this.
