Wujexuhe Rear Tail Light Bulb Socket & Wire Harness for Kia Optima 2014-2015 — Direct-Fit with Copper Wiring

Wujexuhe's 92451-4C500 rear tail light bulb socket and wire harness is a direct-fit replacement engineered to restore reliable taillight connections on 2014–2015 Kia Optima models.

If your Optima's rear taillight is intermittent, dim, or not lighting at all, the fault is often a worn socket or a damaged harness rather than the bulb itself. This replacement part pairs a durable plastic bulb socket with a copper-core wiring harness to bring back a stable electrical connection and consistent illumination. It matches the OEM fitment and the manufacturer reference numbers (92451-4C500 / 924514C500) so installation is straightforward for DIYers and pros alike.

How does this part restore a faulty taillight?

The socket and harness replace corroded contacts and frayed wiring that interrupt power to the bulb. By re-establishing a solid conductive path, the assembly prevents flicker and loss of brightness, and reduces the chance of short circuits that can affect other rear-light circuits.

• Direct-fit for Kia Optima 2014–2015 to simplify installation.
• Copper wiring for improved conductivity and lower resistance.
• Precision-molded socket to secure bulbs and prevent poor contacts.

What are the build quality and materials like?

The unit uses impact-resistant plastic for the socket body and insulation around the harness for durability in everyday road conditions. Copper conductors inside the cables ensure dependable electrical transfer and reduce voltage loss compared with cheaper materials.

• High-grade plastic resists heat, abrasion, and road vibration.
• Copper core wiring for consistent current flow.
• Reinforced connections to minimize wear at plug points.

How easy is installation and what tools are needed?

Installation is typically quick because the part is designed to match the factory connector layout and mounting points. Basic hand tools and standard electrical safety precautions are usually sufficient; you won’t need specialty adapters when replacing the OEM 92451-4C500 unit.

• Fits original mounting points—no cutting or splicing required in most cases.
• Simple plug-and-play electrical connector for fast replacement.
• Recommended tools: screwdriver set, pliers, and a multimeter to verify connections.

Will this prevent future lighting problems?

While new sockets and harnesses reduce the risk of failures caused by wear, they don’t protect against unrelated issues like water intrusion or vehicle wiring faults elsewhere. Used as part of routine maintenance and proper sealing of the taillight housing, this replacement improves reliability and longevity of the rear lighting circuit.

• Replaces worn contacts that commonly cause dim or intermittent lights.
• Improves electrical stability when installed correctly and housing is sealed.
• Not a substitute for fixing unrelated wiring or grounding problems elsewhere in the vehicle.

Who is this for: This Wujexuhe 92451-4C500 socket and wire harness is ideal for Kia Optima owners (2014–2015) and automotive technicians who need a reliable, OEM-style replacement to restore rear taillight function. Choose this part if you’re troubleshooting taillight outages, seeing flicker or dimming under load, or preparing the vehicle for inspection and want a durable, straightforward fix.
