KarSpareHub Toyota Tacoma 2001–2004 Headlight Assembly — Direct-Fit, UV-Coated Lens, Includes Bulb

KarSpareHub replacement headlight assembly restores factory fit and clear night visibility for 2001–2004 Toyota Tacoma models.

These direct-fit headlight assemblies are precision-molded to match the original Toyota Tacoma 2001–2004 fixtures, including compatible OEM numbers and Partslink references. Each unit ships with the high/low beam bulb installed and is sealed against moisture with a durable PUR adhesive and breathable base materials to protect internal components. The lenses have a UV-resistant optical coating to reduce yellowing and maintain light output over time.

Will this headlight fit my 2001–2004 Toyota Tacoma?

Yes — the assemblies are engineered to match the exact mounting points and electrical connectors used on 2001, 2002, 2003, and 2004 Toyota Tacoma models. Compatibility is validated against multiple OEM references so installation is straightforward and swaps in place of the factory units.

• OEM references: 8111004110, 8115004110, 8162004080, 8161004080, 8152004080, 8151004080
• Partslink numbers supported: TO2502136, TO2503136, TO2520161, TO2521161, TO2530140, TO2531140
• Includes high/low beam bulb for immediate use

How durable and weatherproof are these headlights?

Durability is built into the design: a polyurethan (PUR) adhesive creates a continuous waterproof seam, and each assembly undergoes air-tightness inspection to confirm sealing. The base includes a one-way breathable film that balances internal pressure without letting moisture in, protecting electronics and reflectors.

• 100% air-tightness checked during production
• Breathable base film prevents condensation buildup
• UV optical lens coating resists yellowing and surface aging

What kind of light performance can I expect at night?

Expect bright, SAE-compliant light distribution designed to mimic factory beam patterns while improving clarity through the coated lens. The optical components and reflective surfaces are matched to the original specifications to maintain correct cutoff and spread for safe driving after dark.

• Clear lens with UV protection preserves transparency
• OEM-style reflectors for correct beam pattern and spread
• Includes H/L beam bulb tuned for factory illumination levels

Can I install these myself, or do they require a shop?

These assemblies are intended for DIY installation or professional fitment; they use the same mounting points and wiring as the original parts, so most technicians and competent owners can complete the swap with basic tools. If you prefer step-by-step help, reply with "DIY" and we'll provide an installation guide.

• Direct-fit design replaces factory units without modification
• Standard automotive tools are usually sufficient for installation
• Installation support available on request (reply "DIY")

Who is this for? Owners of 2001–2004 Toyota Tacoma trucks who need a reliable, OEM-compatible headlight replacement that balances fit, weather resistance, and optical clarity. It's a practical choice for drivers restoring a vehicle to original condition, replacing damaged or yellowed lights, or upgrading to a freshly sealed assembly with included bulbs and a 3-year limited coverage for regular-use defects.
