WEILEITE Left & Right Tail Light Wiring Harness Kit - Direct

Our review of the WEILEITE left and right tail light wiring harness kit finds it best suited for owners of 2003-2007 Chevrolet Silverado trucks who need a direct, OEM-fit replacement for failing taillight wiring. The single biggest reason to buy is straightforward: this kit is designed as a plug-and-play replacement for OE part numbers 16531401 and 16531402, so it removes the guesswork of splicing or complex rewiring and restores reliable taillight function quickly.

Key Features

• Direct replacement: Fits the stated Silverado model years and replaces OE numbers 16531401 and 16531402 for a like-for-like repair without extra wiring work.
• High quality materials: Constructed with wear-resistant, corrosion-resistant and moisture-proof materials to hold up under road conditions.
• Heat and impact resistance: Wrapped plastic surface and heavy-duty plugs are designed to tolerate high temperatures, impacts and chemical exposure for longer service life.
• Factory tested: Each harness kit is tested to meet or exceed OEM standards to reduce failure risk after installation.
• Complete kit: Includes both left driver and right passenger side harnesses so both taillights can be serviced at once.

Who It's For

This kit is intended for owners of 2003-2007 Chevrolet Silverado 1500, 1500HD (2003-2006), 2500HD and 3500 who have worn, cracked or shorting taillight harnesses and want a direct swap to restore tail lamp function quickly. It is ideal for DIYers and mechanics who prefer a plug-and-play replacement that matches OEM connector locations and part numbers.

Those who should look elsewhere include owners of other truck years or models outside the listed fitment and anyone who needs a custom-length or aftermarket-modified harness for nonstock lighting upgrades. Also, purchasers who require absolute connector interchangeability should verify fit since a few customers reported connector engagement issues.
