I replaced the old damaged Pearson port and starboard running lights with new Perko LED lights. I found them unsatifactory, sent them back to the factory because the chrome came off of one and both of them had water condensation inside. That was two weeks ago after exchanging emails and I have yet to recieve replacements. The LEDs draw less amps and seem to put out brighter light than the orginal units. I just hope that these lights are not another example of good old traditional American products that were so dependible being manufactured in Mexico or Communist China, if so I will look for old USA made replacements.
