Wujexuhe Rear Tail Light Socket & Wire Harness for Kia Optima 2014-2015 — 92451-4C500 Direct-Fit Copper-Core

Wujexuhe 92451-4C500 is a direct-fit rear tail light bulb socket and wiring harness designed to replace the factory unit on Kia Optima models from 2014 and 2015.

This replacement kit restores the electrical connection between the tail lamp and the vehicle wiring, helping the brake, tail and turn signal bulbs receive stable power. Built from durable plastics and copper conductors, the assembly is engineered to resist everyday vibration and exposure under the rear light housing. The part number references (Replace 92451-4C500, 924514C500) match the original equipment for an easier swap and fewer fitment questions.

How does this harness match my 2014–2015 Kia Optima?

The Wujexuhe socket and wiring harness are manufactured to align with the mount points and electrical connectors used on Kia Optima model years 2014 and 2015. The connector pins and wire lengths are sized to plug into the factory loom without splicing for a clean installation. Using a matching replacement reduces fitment issues and electrical faults compared with generic aftermarket parts.

• Direct replacement for OEM part numbers 92451-4C500 and 924514C500
• Connector shapes and pin layout mirror factory components
• Wire length tuned to reach original mounting points
• Plugs into existing vehicle loom—no custom wiring required

What materials and construction ensure durability?

This assembly pairs impact-resistant molded plastic sockets with copper-core wiring to balance mechanical strength and electrical performance. The plastic resists cracking from vibration and temperature changes, while copper conductors provide reliable current flow and lower resistance under load. Overall construction emphasizes stable contact and insulated protection to prevent common tail-light failures.

• Molded plastic socket resists abrasion and flex fatigue
• Copper-core wires for dependable conductivity
• Soldered/crimped connections designed to minimize contact loss
• Insulation to protect against moisture and short circuits

How straightforward is the installation process?

Installation is intended to be plug-and-play for technicians or DIYers familiar with rear lamp removal. The kit mates with the factory connector and secures in the existing socket cavity, reducing the need for electrical tools beyond basic hand tools. In many cases, replacing the harness eliminates intermittent lighting issues and restores normal tail light function quickly.

• Remove tail lamp assembly, unplug factory socket, and install new unit
• No major rewiring or splicing required for proper fit
• Standard hand tools and basic vehicle access are sufficient
• Compatible with the original bulb types used in the vehicle

What common problems does replacing this part address?

Swapping the socket and harness addresses loss of tail, brake, or turn-signal illumination caused by broken connectors, corroded contacts, or damaged wiring. A fresh harness reduces flicker, open circuits, and unreliable bulb behavior. It also helps prevent short circuits that can lead to blown fuses or nonfunctional lamps.

• Stops intermittent or dim tail light operation
• Resolves open-circuit faults from worn connectors
• Replaces frayed or brittle wiring prone to failure
• Helps prevent electrical shorts in the tail lamp circuit

Who is this for? Wujexuhe's 92451-4C500 rear tail light socket and wire harness is intended for Kia Optima owners (2014–2015), independent mechanics, and DIY vehicle restorers who need a reliable, OEM-fit replacement for a failing tail lamp connection. Choose this kit when your taillights are dim, flicker, or have stopped working due to connector or wiring issues, and you want a direct-fit part that restores proper electrical performance.
