4 Pin Male-to-Male Connector for 3528 and 5050 LED Light Strips – 25-Pack
Updated June 19, 2026
This 4-pin male-to-male connector is designed to join two segments of 4-wire LED strip lights, commonly used in RV, camper, and trailer lighting systems—including awning and porch lights. The pack of 25 allows for multiple connections or repairs without soldering, making it a convenient solution for extending or linking RGB or RGBW LED strips that use 3528 or 5050 chip sizes.

Function and Design
Each connector features four male pins on both ends, allowing direct connection between two LED strip segments that have matching 4-pin female sockets. The pins align with the strip's copper pads to maintain continuity for red, green, blue, and common positive (or white) channels. This design supports RGB and RGBW strips where independent control of each color channel is required. The compact, low-profile housing fits within typical strip channels or enclosures used in RV and camper lighting.
Compatible LED Strip Types
These connectors are specifically intended for 3528 and 5050 LED strips that use a 4-wire configuration. The 3528 chips are smaller and often used for accent or under-cabinet lighting, while 5050 chips are brighter and common in RGB color-changing applications. Both types share the same 10mm-wide strip and 4-pin layout, making this connector compatible with many aftermarket and OEM RV lighting systems, including awning lights, porch lights, and interior strip lighting. Always verify your strip's pin spacing and pad width before use.
Installation and Connection Tips
Installation is solderless: simply insert the stripped end of the LED strip into the connector's slot until the copper pads contact the pins, then snap the locking lid closed. Ensure the strip is oriented correctly (arrows or markings on the strip indicate direction). For outdoor or damp locations (e.g., awning lights), apply a dab of silicone sealant around the connection point to prevent moisture ingress. The male-to-male design is ideal for bridging two strips end-to-end; if you need to connect a strip to a power source, a male-to-female or wire-pigtail connector is required.
Troubleshooting Common Connection Problems
If a connected strip segment fails to light or shows incorrect colors, first check that the strip is fully inserted and the locking lid is secure. Corrosion or dirt on the copper pads can cause intermittent contact—clean pads with isopropyl alcohol if needed. Use a multimeter in continuity mode to verify each pin is making contact with the corresponding strip trace. If one color channel is dead, the connector may be misaligned or damaged; replace it with another from the pack. These connectors are not designed for high-current loads; for strips longer than 5 meters, consider parallel power injection to avoid voltage drop.
