Good To Know

Q: What causes rear light sockets to melt? A: Loose electrical contacts generate resistance, which produces heat that can melt plastic housings over time.

Q: Is splicing required to install the new plug? A: Yes, the replacement harness plug must be spliced and insulated into the existing vehicle wiring loom.

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