If you have a set of christmas tree lights that are giving you problems and not working you will have to do something called troubleshooting.
Christmas lights have been one of the most popular christmas decorations for the past century.
Rated 5 out of 5 by san3help very sturdy we just finished putting away and packing up our christmas tree and used the new christmas tree storage bag..

Our waterfall lights are completely self-contained, meaning all you need to do is plug them in and watch the custom controller sequence of the lights in a soothing manner.
A somewhat common problem, especially if you daisy chain your lights, with one string plugged into another, is a blown fuse.
Michael, thank you so much for showing me how to change a fuse in Christmas lights!!!!!!!!! Do you know by any chance where can I buy replacement plugs (with fuses) for christmas tree lights.
Cheap strings of molded LED Christmas tree lights are finally hitting the market in quantity. Unlike traditional green plastic incandescent Christmas tree lights, which have a multi-part plug socket arrangement at every lamp to allow replacement of the incandescent bulb when it breaks or the filament pops, these sets are injection molded, with an LED sealed up in the middle of two shots of resin. Here is how we rewired the cheap 120vac series-wired LED strings for Festival of the Forest. Yes, it was quite a bit of work - that's why they make Christmas lights and most of the other crap you haul around in your pack in sweatshops in Asia - but in fact all you need to do this rework is a table, some yogurt tubs, some nail-clippers and some tape.
The goal from my POV is to get the current consumed in the diode relatively large - or at least exactly as bright as you want it to be - and the current that is wasted in the resistor relatively small, or at least as small as is practical.
After you clip the LEDs out of the series strings, and before you do the POLARITY step, you need to strip the ends of the leads back so that you can connect them again. Before you can use the LEDs that you have cut out of the 120 vac series strings, you must polarize them.
Each 120 vac mini-ice Christmas Light string gives close to 100 of these socketed LEDs, so the unit-cost of an LED with a diffuser and a cool easy-to-handle package is very very low. If you run a single 20 ma 2 volt yellow or red LED off a 12 volt supply (10 AA NiMh batteries) you need a 570 ohm resistor, but that gives you 20 mw to make light in the diode (it will run very bright at 20 MA) and 179 mw of wasted heat in the resistor. Here is a series string with 6 yellow 2.0 volt junctions, each junction dissipates 20 ma at 12 volts at full brightness. However, if you do it this way, when the battery voltage drops below 12 volts, the LED lights will go out.
My preference is to put the resistors between the cells of the battery pack, whenever possible. When you start playing funky wiring attached to high-current-capacity power sources like D cell packs, surplus Lithium Ion batteries, or car batteries in RV's and motorbikes, this becomes a safety issue, and even if all you are dealing with is watch batteries in costume parts, limiting dicharge rate matters. Choosing the right resistor(s) for your light toy is really easy if you understand how to use the online current-limiting resistor calculator that Rob Arnold put up - I have a link to it near the top of my slice through the internet page so if you lose the bookmark or lose this page, you can find it on my site.


Working with inirgee's mini-ice packaged LEDs is pretty easy compared to working with bare LEDs, because each LED is encased in a molded plastic diffuser, but most LEDs come packaged in a lens that directs the majority of the emitted light right out the end. Mounting the LED in the bottle is easy in principle - you just punch a hole and stick the LED thru it. For most of the installations at FOTF we used the bottom of the bottle, like a cup, with holes punched around the sides for the LEDs. Start by clipping the individual lamp-socket units out of the 120 volt light strings, just as you did for the LEDs above. While you are clipping light units out of strings and someone else is tearing light-plugs out of sockets, and someone else is ripping incandescent lamps out of the plugs, and someone else is stripping off the insulation on the ends of the lead-wires coming from the sockets, have someone precutting the leads of the LEDs to the right length with nail clippers or more appropriate tools, using a fixture of some sort to automate the measurement. At least one wire of the LED needs to be insulated, to avoid short-circuits if the LED gets accidentally twisted in the socket.
Stick the LED leads through the plug and out the holes that the incandescent lamps wire's used to exit through and bend them up into the notches in the plug. After you install the LED-equipped plug into the socket, you need to test it for functionality and mark the polarity.
After each unit has been tested and polarized, I recommend using a drop of hot-melt glue to lock the plug into the socket. And of course there are now high powered LUXEON and UFO emitters, and the long-overdue almost-cheap-enough pulse-width modulated power supplies that are finally reaching the market. These technologies allow dimmable, energy efficient, low-voltage lighting and offer the potential for creating very sophisticated color-adjustment options.

While a single bad bulb can’t take out an entire string of modern Christmas lights, there are still things that can go wrong with your lights. You can easily pop them out with a small screwdriver and replace them if they’re shot.
We used the antique candle-light and 4-color mini-ice strings that we got from inirgee and other sources and rewired the socketed LEDs into parallel and series-parallel strings for light toys, balls, parasols, etc. Actually they are already polarized - but the polarization is hidden inside - which is the reason that you have to mark them on the outside so that you can recognize their polarity and connect them correctly. Better to connect six 2 volt LEDs in series for 12 volts - then all the current goes into making light and almost none is lost in heat.
Reasons are simple: a resistor between the cells of a multi-battery power-pack can function to limit current available from the cells, which means it not only controls the brightness of the LED, but more importantly the rate of discharge from the battery pack. If the wiring shorts somewhere, you don't lose your batteries in a puff of foul smoke, all that happens is a few of the lights go out. You could hang 2 LEDs in parallel on this resistor and still get 20 ma through the circuit.
The basic rule of thumb is that a single 47 ohm resistor will drive a 2 volt LED from a 3 volt source at 20 ma.


After that we could measure the resistance and make more like it, using fixed resistance values. This is a mixed blessing unless you want to shine light on something to illuminate it, like a sign. I recommend plastic PET drinking water bottles (or pop bottles if you have a way to wash the sugar out of them). In fact, this can be tricky, becasue you really ant to be able to prewire the LED strings and then install them in the fixtures and it took a 12 year old boy Jake Moulton to show us the trick for mounting odd-sized objects in imprecise holes.
Some installations wanted the light to shine obliquely, and for these we used the necks of the bottles with LEDs pointed out radially, which allowed the light to point obliquely up or down.
The parts may look the same to you, but parts from different manufacturers NOT work in some combinations, so do not mix parts from different strings.
I use fancy electronics cutters that have magnetized blades so that I don't get LED leads stuck in my feet after the cut-off ends shoot off the blades on the cutters. Slip a length of the green plastic insulation that you stripped off the green lead wires onto one of the leads.
I am embarked on the task of replacing the halogen lighting in my Airstream with LED, Luxeon and UFO lighting.

The instructions also show where (and why) we put the batteries and resistors in the circuits to provide the correct power supply voltages and currents that various LED colors require. A pair of 47 ohm resistors in parallel is worth 24 ohms (47 divided by 2) three is worth 18 ohms (47 divided by 3). For the moment, I am going to assume that it is a benefit taht you are using bare LEDs, and that you have some objsect that you need to illuminate from within. I have no idea where he saw the ide first, maybe the push on axle-caps on some toy he had a child, but he watched us struggling to make accurate hols and pointed out that a cluster of 4 holes would create an opening with barbs that held the LED and he was right. Safest approach is to use plastic tubs (white plastic yogurt tubs are perfect) to keep the pieces from each string together all the way through the manufacturing steps that follow, all the way through to the hot glue. A strand is made of clear wire with 96 blue LEDs, each spaced six ” apart for a total of 960 LEDs in a waterfall set.
However you choose to strip the wires, you will end up with many short lengths of green plastic tubing.
I do this by soldering wires to the battery with a clip on one wire and a bare end on the other. Or you could put a resistor on each LED to get them each full bright, OR you could put two resistors in parallel, right at the batteries.
For starters, the come in a wide range of sizes, nifty colors (clear, green, blue, etc.) and they offer multiple angles.
When an LED socket is correctly connected, the LED lights up and I mark the side where the clip is attached.
This means that you can set the battery pack for the brightness you think you need by starting out with the right resistance value and then making minor adjustments. The best way to ensure a complementary color fit would be to sample different sets and compare.As a note, our warm white lights have become fairly neutral over the years and don't have as much yellow as they once did. Place votive candles into each hole and then encircle the log with a strand of our battery operated Christmas lights.
