AS Headlight Assembly Compatible with 2005-2006 Toyota Tundra Double

In this review the AS headlight assembly is evaluated for owners of 2005-2006 Toyota Tundra Double/Crew Cab and compatible 2005-2007 Sequoia SR5/Limited models who need a direct replacement that looks factory-original. The bottom line: this assembly delivers a close OEM fit, strong waterproofing, and noticeably improved reflector brightness, making it a practical choice for drivers who want a plug-n-play swap without modifying wiring or mounts. It is best suited to four-door Double Cab trucks; buyers with regular or access cabs should look elsewhere.

Key Features

• Direct OEM Fitment: Designed for 2005-2006 Tundra Double Cab and 2005-2007 Sequoia SR5/Limited, it fits as a replacement without altering the vehicle.
• High/Low Beam Output: Uses H4 for low/high beam and 3157A for turn signal, enabling standard bulb choices and conventional beam patterns.
• IP65 Waterproofing: Fully sealed structure and quality PC lens keep moisture and debris out during rainy or snowy driving conditions.
• Superior Reflectivity: BMC reflector bowl delivers a high reflection rate for brighter, clearer output compared with worn original lenses.
• Plug-n-Play Installation: Bolt-on design allows an installation in roughly 15 minutes with no vehicle modifications required.
• One Year Warranty: Backed by a one year return policy for quality issues, with seller support available through the product question channel.

Who It's For

This headlight assembly is for owners of 2005-2006 Toyota Tundra SR5 or Limited four-door Double Cab models and 2005-2007 Toyota Sequoia SR5 or Limited who want a straightforward replacement that restores a factory appearance and improves brightness. It suits DIY installers who value a bolt-on, plug-n-play swap and expect reliable waterproofing for varied weather and road conditions.

It is not for Tundra regular cab or access cab owners, as those configurations are explicitly incompatible. Buyers who need aftermarket projector optics, LED conversions, or different mounting geometry should seek a product designed specifically for those upgrades.

Pros & Cons

Pros

• Easy to install with a bolt-on, plug-n-play design that typically takes under 15 minutes.
• Quality materials and IP65 sealing reduce the risk of moisture intrusion compared with aged originals.
• High-reflectivity BMC reflector improves light output and on-road visibility.
• Matches factory style closely, refreshing the truck's front-end appearance.

Cons

• Fitment receives mixed reports; some sellers and owners note minor alignment or adjustment challenges during installation.
• Bulbs are not included, so separate purchase of H4 and 3157A bulbs is required.
