SUPERNIGHT 10 Pack 4 Pin LED Connector for Waterproof 10mm RGB 5050 LED Strip Lights, Strip to Wire Quick Connection without Stripping, Include UL Listed 16.4ft 22 Gauge 4 Conductor Extension Cable

Excellent product and seller

Works great and easy to use. A must to extend your RGB strip.

Every single one worked as it should. Just take your time and have good lighting. Be sure to open the lid on the light strip side 90 degrees before inserting the light strip in. Also remove the adhesive tape from the back of the light strip. I forgot on one connection but it still worked. On the wire side be sure the wires are laying in the brass grooves properly before you snap it together. I had one wire that didn't and it caused one color to not light. I could see through the cap that one wire wasn't laying right. I just unsnapped the lid and moved the wire and re snapped the lid. Works great.

These are tough to use. I work on car/ machinery electronics so I am pretty savvy to wiring. It's important to follow the instructions to a tee. (the instructions are in the pictures by the item description. Here's the most important points to follow: make sure you use the proper indoor or outdoor connectors. You cannot intermix indoor connectors with outdoor light strip or vise versa.Be sure to cut exactly on the line (too short or too long past the line and you may not make good connection.)Be sure to peel off the sticky back before using a connector (this makes for a bad connection; in my case I lost connection to the green wire so was unable to make all my colors: fyi, the metal connector terminal pushes up, from the bottom through the paper to make contact so if you leave that paper on there they may not all make contact).Be sure and lift the connector lid the full 90 degrees- it says this for a reason. If you don't lift it all the way back then you can't always make full contact with terminals. I did find where I needed to adjust the distance forward or backward just slightly, at times.Ultimately, I had to connect and reconnect several times to adjust the distance and the connection before I got it right. There's no margin for error...it has to be crimped perfectly. If I have anything else to add later, I will edit my review.

I purchased a 10 pack of the 2 pin led connectors thinking it would save me some time over icreating’s connector that includes 4” or so of wire attached.Boy was I wrong. I’m a fairly handy guy. I’m a mechanical engineer by trade and I do a lot of home projects. I’ve done basic wiring in the past and had no issues.I spent 3 days trying to string together 2 strands of LED strips. These things had me doubting myself time and time again. As it turns out, these pieces of crap do not actually conduct electricity from the connector to the wire. It took a hours of troubleshooting with my volt meter and trying various things to get these things to work.I did eventually get one to work by stripping the wire and doubling it back on the unstripped part of the wire before inserting it Into the guitine style connection. However this method was not repeatable due to the inherent short circuit you’ll get if the two stripped ends touch.After a few days of self loathing and annoyance, I ordered the icreating strip to wire connectors and my project jumped into light speed. Easy to use and my I had my skills back. I felt like the guys in Space Jam after they got their skills back from the evil aliens.Don’t let this crap product waste your time and get you down. Find another option

I wen't through 5 of my 10 trying every possible way I could think to make these work. My best connection was still flaky. No instruction on proper trimming of the tape light. This product is very frustrating and just doesn't work.
