Thanks so much for posting this guide! My outdoor light strings are far from waterproof and I live in a rainy climate (yes, even in December), so my original LEDs corroded badly and the strings stopped working.
I ordered a whack of replacement LEDs using the reference numbers you provided. Replacement was simple. The results were spectacular -- better than I had dared hope. For $10 and a few minutes work, I kept $200 worth of strings from getting tossed. Thanks a bunch!
