Tip: Fixing Pre-Lit Christmas Tree

Here is your solution. Find the non-removable bulb with the white socket. It is the last one on the strand, I believe the "non-replacable" white bulb exists only so that you have to buy a new tree ever four years. :(

You will find that it's blackened or burned and causing your problem.

Wiggle out the bulb, then dig out the socket with a pair of pliers. Be careful not to destroy the socket. Take your time, wiggle it loose. Stick any replacement bulb into that socket and, BAM, your tree will be perfect again!

    Question: Pre-lit Christmas Tree Lights Keep Going Off and On

    The top section of my newly bought tree keeps going on and off. It seems when they are on and I try to adjust the branches the lights go off. Then when they go on again they stay on indefinitely as long as I don't touch the branches. Any help would be greatly appreciated.

    Sounds as if your tree has a short in the wires. I would return it or call electrician or someone you may know to take a look at it. Don't want your house to catch fire.

    Question: Trouble Connecting Lights on a Pre-lit Christmas Tree

    No one seemed to understand the problem with my pre-lit Christmas tree. Anyway my tree has a main hot wire that runs up the center of the tree. The tree also has lots of plug-in ones that will connect to the main wire on each section, then the other plug-ins that will connect to each other so each section will burn.

    My problem is getting the main one plugged in the right socket so I can work my way up the tree. All fuses and lights are OK. Will someone give me some idea how to get all these plugged in? Or tell me which one plugs to the main hot wire on each section? There are no color codes on the plug-in. Thanks

    I did what redhatterb suggested, but then I made a diagram showing which branch numbers get plugged into the tree plug and which get plugged into the previous branch's plug. I keep this diagram in my tree storage container in a plastic sleeve. It's made putting the tree up each year much easier.

    Question: Partially Working Lights on Pre-lit Tree

    I have a four section pre-lit LED Xmas tree. After five years, the top two sections remain fully lit. On the bottom two, some branches light up and some don't. If a bulb is removed from a branch that lights up, the rest of the lights stay on. Each plug for each section lights up some branches. I have changed out the fuses in each plug and still some branches don't light up. I have checked the wires and can't find any damage. Any suggestions?

    Have you used the tree before and has it worked. Someplace on the bottom tier there has to be a male plug. When I put my tree together, I always plug in the bottom layer, then when I do the next layer, I know when I get the next layer plugged in just right, etc. Putting these trees together and getting them working, can be a real pain, and there are times I feel like I almost stick my head into the branches to find the right connections, but by plugging in the first tier and then each successive tier after that, it is easier than not plugging it in layer by layer.

    I have had the same issue and I'm getting ready to take mine back to Costco. The first year I had the tree it was perfect. The issue you are having started for me the second year where those white encased bulbs started burning out. Why did they make an irremovable bulb that burns out easier than the others? I have no idea.

    If you twist and pull on the bulb it will come out and leave the white casing in. This will likely break the copper wiring from the bulb which will stay stuck in there. Get a pair of needle nose pliers and stick one side into the socket (unplug your lights first :)). Try gently pulling or scraping up to remove the white casing. If it doesn't come out easily, apply more pressure. If it comes up a little bit but is still stuck, just try getting a grip on the white casing and pull it out. It will likely tear slightly, but that's okay.

    Get a replacement bulb from the little bag that came with your tree. Remove a bulb from the green casing. Make sure any broken wire has been removed from the white casing. Place the replacement bulb into the white casing so that the two wires go through the two holes in the bottom then fold the two wires up and then stick the whole thing back into the tree.

    The good news is I think I have replaced nearly all of my white encased bulbs over the last 2 years and the ones I have replaced seem to not burn out.

    I also recommend plugging your tree into a surge protector.

    Question: Repairing a Prelit Christmas Tree

    My mama left me her pre-lit Christmas tree and her lifetime collection of antique ornaments. So, needless to say, I'm willing to do whatever it takes (short of setting my house on fire!), to fix this tree.

    Anyway, last year when I plugged in the tree only 3, yes 3 sections of lights lit up. Please understand, 3 limbs "did not" light. Only 3 small sections out of about 500 limbs! At that point I went searching and found what I consider to be one of the hidden wonders of the world, "the Christmas Light Fixer Gun". And it was wonderful! It fixed "every" light on the tree with the exception of one portion of the very last limb on the bottom of the tree.

    So, this year I was ready "to do battle" with my trusty fix-it gun. What a disaster! Part of the lights on limb sections would burn, half wouldn't. Various lights on various sections of limbs got "really" bright then burned out completely, some of the bulbs themselves were fine when I tested them, others were black in the center and completely blown to kingdom come. You should also know this tree has 16 strands of lights that all meet at the bottom of the tree. They don't plug in to separate outlets on the "trunk" of the tree. All strands of lights provide converge at the base of the tree.

    I'm already facing one problem, the replacement bulbs I have, don't have wires long enough to fit in the green husk. Any information anybody can give me will be incredibly welcome. I do have one more question. Is there any such thing as a complete replacement light kit to replace the lights throughout the entire tree? Thank you for your time and hopefully your suggestions!

    It is very important to make certain that none of the bulbs are loose. That is usually the problem. They can become loosened in shipment or just getting them out of the box and putting them up. If you have ONE bad bulb and it's still in tight, the others will remain lit, and of course check the fuses in the plug, if all else fails...

    Question: Is It Safe to Remove the Fuse Light from a Pre-lit Tree?

    The problem is in the fuse bulb. It is a very bad design because it is not replaceable and when it blows the entire string goes out and this is a real problem on a pre-lit tree. Why there is a fuse bulb on top off the fuses in the plug itself is beyond me. On my tree, only one year old, five of the fuse bulbs had failed!

    GE sent under warranty three new strands but I really didn't want to thread them all in on top of the dead bulbs and wires, so I did this: (1) unplugged the tree (2) pulled on the fuse bulb until it came out (3) carefully, with an ice pick, levered out the white fuse bulb socket enough to use a pair of needle-nose pliers to fully remove it (4) with those pliers, molded it back into shape (5) from the spare bulbs, removed one from its green base and threaded it into the white base (6) put the bulb and white base back into the socket (7) with the needle-nose pliers, pushed it back down fully.

    Result: A beautiful tree, fully lit again. Yes, this supposedly violates the warranty, but I already have three free new strands I'm now not going to use, but will keep just in case.
    GE really needs to make that fusible bulb replaceable (and provide spares); otherwise, get rid of it entirely.

    I have the Trim-A-Tree9 with GE bulbs. Same problem described, except that I had three of the white-base bulbs appeared to be burned. I pulled one apart and confirmed the bulb was dead with a multimeter. I went to Ace Hardware to find a replacement. Problem is there was no data on the bulb, so I used a regular replacement bulb without a base and something interesting happened. The lights came on, but that new bulb blew out immediately.

    I found two more white-base bulbs that appeared burned and did the same procedure. Same results. But, the rest of the tree lights up. I am worried that those white-base bulbs may be surge protection, but what a crappy design. The fuses in the plug are supposed to provide that protection. If this tree fails again, I'll replace it with a regular tree and then buy LED lights. Note to GE: Is this really the best you can do?

    I bought a pre-lit Christmas tree from Elder Beerman's after-Christmas sale. The tree was a display tree, and for some reason when it was taken down all the light sets were unplugged. It has been a total nightmare in getting the lights to work. The tree was put in a different box with the wrong instructions. I have no idea how to even plug the lights up without the schematic diagram.

    RE: Pre-lit Tree Lights Not Working

    With the pre-lit trees, sometimes you will get a pinched wire when folding it back up to store it. If you have a hinged tree, you can light it in sections with regular strings of lights and leave them on, so all you have to do the next year is plug them in. If you have to replace a strand, it's not hard. (12/20/2008)

    We have a tree we purchased from Kmart last year on clearance. It's great and I love it, but the lights were starting to go out already. Found this site as a result of the google search I did, and we tried to locate the "safety" lights and ended up cutting them out of the circuits and splicing the lights together. Worked very well. I may get the LKP also, as there are still some areas which aren't lit up, but it's way better than before we started removing the "safety" lights. On our tree in particular, there was no white, the safety ones were blackish green and clearly had no way to remove the bulbs. (12/23/2008)

    By NHLinda

    RE: Pre-lit Tree Lights Not Working

    I noticed several posts in this area that mention eliminating or shorting out the safety fuse lamp. While it might make the string of lights work, it's not a good idea. They use small wires on these light strings and the tree is usually plugged into a circuit supplied by a 15A breaker; a lot more than the small wires can safely handle. The safety fuse lamp is in there to keep the tree from catching on fire if certain fault conditions should occur.

    A better approach could be to cut out the safety fuse lamp and replace it with a splice-in fuse holder for AG type fuses. A small amp fuse, 1 - 5 amps, rated for use on a 120VAC circuit (assuming USA here) should work fine. Just so there is something in there to open the circuit in case of a fault. That's better than having the wires heat up and catch on fire. (01/14/2009)

    RE: Pre-lit Tree Lights Not Working

    I solved the problem on my tree. The "safety bulbs" appear to be a "safety" for the manufacturer so the strings will all go out eventually and force you to buy another tree. They are simply bulbs without a shunt. I was able to pull the non replaceable white bulb bases out of the sockets with pliers and dental picks and I replaced the bulbs with ones that had shunts using the same white bases, and everything works fine.

    If you can't get the white bulb bases out, you could just cut the socket out of the circuit and splice the wires together. The only result will be slightly brighter lights since you've removed a little resistance from the series circuit (12/09/2007)
