Did you know?
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

Newbie Seeking Help with LED Rope Light

Recommended Posts

As the post title indicates I'm a newbie, both in terms of Planet Christmas (this is my first post here - yeah me!) and in terms of rope lights and I'm hoping the community can be of assistance.

I just completed my first cut and power lead installation with initial success (i.e. the LEDs lit up - on the work bench). 

Went to move the string and the power lead fell off; clearly I didn't adequately tighten the compression nut.

Here's the problem:  I've been unable to successfully re-connect the power lead (i.e. I'm not getting power to the LEDs).  I'm wondering if my multiple efforts to re-connect the lead have messed up  the internal wires to the point I can't make a connection.

Any suggestions for potentially remedying this issue that don't require me removing a whole section and starting over?

Thanks in advance for any suggestions.

LED rope light unlike the old incandescent rope light needs to work on Direct Current (D.C.). The power cord for LED rope light contains something called a rectifier bridge (usually hidden in a plastic "lump" in the cord) which turns the Alternating Current (A.C.)from your wall plug into the Direct current to power the LED's in the rope. The LED's in the rope must be connected in the right polarity (plus and minus like a battery) to the D.C. Power cord in order to light up. if the two pins or barbs on the power cord are stuffed into the end of the rope light the wrong way around, it won't light. Try pulling out the power cord from the end of the rope light and reversing the position of the two pins (thus reversing the polarity of the connection) and see if the LED's light up. Also many power cords have small glass fuses hidden in the plugs, this is also something to check...
