虽然这些灯有三年保修期，但自己修灯比付邮资寄回要便宜。我从Digikey购买了T1 3/4（5毫米）LED，寻找任何颜色合适的800 mcd或以上范围内的东西。我最终买了：
Hi! Can you tell me the difference between the two types of light bases you show above? The situation I have is I bought a set of the clear LEDs figuring we could get replacements since my husband prefers the colored ones. But, once we started pulling them apart, we found the different sized bases and the only replacement ones I could find had the short stubby base. Are they interchangeable if we pull the bulb out of the base? Do you have any suggestions for us? Thanks for any help!
The reason for the two different size sockets is that if you look at your strand, every so many lights three wire come into the socket instead of two. I think (and this is only a hypothesis) than the shorter sockets are to allow room for the connection of the third wire. Why they didn't just use short sockets for everything I don't know. But it seems likely to me that the short one would work everywhere. I have not tried it.
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!
