LED Replacement lights

Install an upgraded LED in a strand of LED christmas lights.

Although these lights have a three-year guarantee, it really is less expensive to fix them yourself rather than pay the postage to send the lights straight back. I bought T1 3/4 (5 mm) LEDs from Digikey, in search of everything in 800 mcd or up range into the proper colors. I wound up buying:

404-1096-ND (red)

404-1097-ND (orange)

C503B-BCS-CV0Z0461-ND (azure)

C503B-GCN-CY0C0791-ND (green)

404-1092-ND (yellow)

The LEDS are wired in show in teams- three teams to a-strand. If one LED inside team has failed, not one in that group will light. The secret is to find on which one (or ones) is bad.

Its easiest when you yourself have one working strand or section of a strand. In that case, remove one LED through the good strand, and use that socket to test each LED, individually, through the bad strand. In the event that LED doesn't work in the good strand, replace the Light-emitting Diode in accordance with the directions that follow. There could be multiple bad one, so after replacing, in the event that bad strand still does not light up, go on to another Light-emitting Diode.

If you don't have a good strand to test with, and do not have one other way to evaluate the LEDs, then pull each LED, individually through the bad strand, and check the causes be sure they truly are maybe not broken. If broken, replace, if not, place the LED back and carry on to another location one.
