Specs At A Glance

Good To Know

Q: Will these sockets work with LED bulbs? A: These connectors are compatible with standard 3157 and 4157 LED replacements as long as the base matches the socket configuration. Some LED setups may require additional resistors to prevent hyper-flashing.

Q: How do I identify which wire is the ground? A: Typically the black wire acts as the ground, while the other two handle low and high brightness circuits. Verifying with a multimeter before final installation is recommended for proper circuit matching.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
