Product Review

This page features the pair of 3156 size pre-wired sockets fit for most:

• Chevrolet Silverado
• GMC Sierra
• Compatible bulb size include: 3056 3456 4156

Because this is a "one size fit all product", you may still need to make slight modifications if necessary. To ensure exact fitment, compare your adapter with the gallery images' to make sure they match before purchasing this product.

Due to the design of this socket adapter, the long curved tab on the back of the adapter is fragile and can be easily broken; however, the small tabs on the front of the adapter are what will be used for the fitment and the adapter will still fit and function properly and can be firmly installed without any issues.

Each harness socket includes two wires and installs easily with a plug-and-play process. You won't have to worry about any parts melting since each socket is heavy duty, highly efficient and heat-resistant. Get reliability you need to keep your turn signals, daytime running lights, and tail/brake lights working or upgrade them to LED.
