If you are having trouble with wiring the light bars up without a relay, then you may want to try the third option. You may want to consider using a simple manual switch that will not allow power to pass through it. Let's see how to wire LED light bars this way.
The first thing you need to do is find an old light bar and remove the three screws holding it down. You will also need to remove the old led light bulb so you can reassemble the light. The second thing you need to do is to locate the four screws that hold the two sides of the led strip in place. Remove these screws one at a time.
When you look at the led strip, you will notice that there are four terminal holes on the edges. These are what you need to plug into. If you are unsure about which pins go where, you can use a soldering iron to trace the connection on each side of the strip. This way, you can figure out which pin goes where.
Once you have plugged in the terminals, you will want to make sure that the led strip is facing away from the wall. If it is facing towards the wall, then the light bar will be powered up, but if it's facing away from the wall, then it won't be. It's always good to plug the led strip in and test it out before powering it up. It's a good idea to leave it running in a corner of the room, with the led strip facing away from the room and all the light fixtures.
If your strip is facing the wall, you need to install a new circuit board. The last thing you want to do is to find out later that the strip is stuck in one position because it's facing the wall. First, take out the old strip and resolder the power wires. Take the new strip and place it over the power wires. Connect them to the relay, as well as the ground wire. Next, you should check that the led strip is facing away from the room. If it is, then you are ready to install the new circuit board. Take the new strip and place it over the power wires.
To finish off the wiring of the strip, take the power wires and connect them to the relay. Once this is done, solder the lead wires to the circuit board. Make sure to keep everything as close to the original orientation as possible. After you have completed the wiring of the strip, you will need to turn it on. If the strip is already wired up, you will see that the led strip is lit up. You should be able to adjust the led strip according to the color you wish to use. To change the led strip color, you simply need to adjust the led strip until the color you want is being displayed.
When you turn on the led strip, you should be able to turn the lights on or off. Once you've completed this step, you should be able to set the led strip back on its own. Now, all you need to do is hook up the relays and you're good to go. Just be sure that you will not be putting any more power into the led strip. You should only need to power it up from the wall, when it needs to be turned on for some reason. You should not have any trouble connecting it to the power source.
