RGB Strip-to-Strip Connector Troubleshooting

(Shop our range of RGB strips and kits here)

Chances are if you've done or are doing installations requiring making "jumps" to different locations, you will be using our strip-to-strip connectors to do this.  There is also a distinct possibility of running into issues such as flickering or variances of color between strip-to-strip connections.  This blog post will discuss issues with color variances regarding use of our RGB strip-to-strip connectors and how to solve these issues.


First things first, we need to make sure your strips are plugged in the right way. In other words, make sure the black wire (ironically the positive wire in this case) on the RGB strip connector is on the same side as the '+12V' symbol located on one side of each strip. Now that you've figured out which end of the strip is positive, line it up with the "+" end of the connector, which is indicated on the white connector box. If you've got the polarity right for both strips, then let's move onto step 2.


With the polarities right, we can turn the lights on.  To make the rest of these steps as easy as possible, set your strips to white once you've turned them on. If your first strip lights up white, but your second strip doesn't light up at all, or displays a color other than white, then we've got a bit of an issue and we'll need to look a little closer at these connections, which can be finicky to work with sometimes.


If the LED strips aren't both coming up white when you set them to white, then pop open the connector boxes to see the LED strip's connections. Below is a list of a few situations regarding the LEDs color (or lack thereof) and what may be happening here:

- No color:  +12V circuit/copper pad not making good connection with metal pin in connector
- Purple/Pink color: green circuit/copper pad not making good connection with metal pin in connector
- Yellowish color: blue circuit/copper pad not making good connection with metal pin in connector
- Aqua/Blue-green color: red circuit/copper pad not making good connection with metal pin in connector

In case you need to adjust the light strips and metal pads with your bare hands, there's no need to worry because our LEDs run on 12 volts DC, and there is no shock danger there! With the connector box open, we need to check and make sure that LED strip's oval or circular copper pads are properly lined up with the connector's silver pins. If you can see that they aren't aligned right, gently move the strip back and forth until the strips light up properly, this usually fixes connection issues!


While you're attempting to realign the LED light strips, watch your second strip (the one that wasn't lighting up right) and wait for it to start behaving properly. Once the strips are working as intended, snap the connector shut and marvel at how great a job you did and how awesome you lights look (marveling takes a minimum of twenty to forty minutes and is a completely necessary step for the connection to remain solid.(I'm serious.)) 

The below video shows troubleshooting steps for single color strips, but is a good reference for RGB strips also.
