Although these lights have a three-year guarantee, it's cheaper to fix them yourself than to pay the postage to send the lights back. I bought T1 3/4 (5 mm) LEDs from Digikey, looking for anything in the 800 mcd or up range in the proper colors. I ended up buying:

404-1096-ND (red)

404-1097-ND (orange)

C503B-BCS-CV0Z0461-ND (blue)

C503B-GCN-CY0C0791-ND (green)

404-1092-ND (yellow)

The LEDS are wired in series in groups- three groups to a strand. If one LED in the group has failed, none in that group will light. The trick is to find out which one (or ones) is bad.

Its easiest if you have one working strand or part of a strand. If so, remove one LED from the good strand, and use that socket to test each LED, one at a time, from the bad strand. If the LED doesn't work in the good strand, replace the LED according to the directions that follow. There may be more than one bad one, so after replacing,if the bad strand still doesn't light up, go on to the next LED.

If you don't have a good strand to test with, and don't have another way to test the LEDs, then remove each LED, one at a time from the bad strand, and check the leads to make sure they're not broken. If broken, replace, if not, put the LED back and go on to the next one.

Kılavuz Adımları

Adım 1

Retirez le cache de "l'ampoule". Le couvercle de l'ampoule se tire, certains sont plutôt durs à tirer, mais ils finissent par sortir. Ils ne se dévissent pas.

Adım 2

Enlevez la LED et sa fiche. Dans les connecteurs que j'ai, il y en a deux styles différents qui ne sont pas interchangeables.

Adım 3

Enlevez la LED défectueuse de la fiche de sorte à ce que vous puissiez réutiliser la fiche. Notez que la nouvelle LED a une patte plus longue que l'autre.
