BICYACO 4x6 Inch LED Headlights 4-Pack DOT 6500K White Rectangular Plug-and-Play IP67

BICYACO 4 PCS 4x6-inch DOT LED headlights are durable, plug-and-play rectangular replacements that deliver bright 6500K white high/low beams for compatible trucks and classic cars. These four LED headlamps are designed as direct-fit replacements for common 4x6-inch rectangular housings found on heavy trucks and older passenger vehicles. Each lamp is DOT-approved for use in the U.S. and Canada, built with an aluminum alloy housing for heat management, and sealed to IP67 standards to resist water and harsh weather. The set includes H4/9003 wiring harnesses to simplify installation and an integrated anti-flicker circuit so lights remain stable after fitting.

How do these headlights perform in adverse weather and temperature?

The BICYACO LEDs are IP67-rated and tested for operation in cold and wet conditions so they keep functioning through rain, snow, and freezing temperatures. The sealed housing prevents moisture and debris ingress while the aluminum body disperses heat to maintain component life.

• IP67 waterproof rating for protection in storms and road spray
• Aluminum alloy housing with heat-dissipation fins
• Durable LEDs rated up to approximately 50,000 hours lifespan

Will these work as a direct replacement on my truck or car?

Yes — these lamps are made to fit standard 4x6-inch rectangular headlight openings and come with H4 (9003) wiring harnesses for a quick plug-and-play swap on many models. Check the vehicle’s headlamp socket and mounting to confirm compatible fitment before installation.

• Includes 4 H4/9003 wiring harnesses for easier hookup
• Compatible with common models like Kenworth, Peterbilt, Freightliner, Chevy trucks and older passenger cars
• Mounts into existing 4x6-inch rectangular housings — usually under 20 minutes per lamp

What light output and beam control do these headlights provide?

The LEDs produce a pure white 6500K color temperature with both high and low beam functions. The optics are designed to create a clear, straight cut-off that helps illuminate the road without glaring other drivers, providing a wider, brighter view than many halogen replacements.

• 6500K bright white color for improved night visibility
• High/low beam functionality in each lamp for flexible use
• Engineered cut-off line to minimize glare to oncoming traffic

How easy is installation and are there anti-flicker protections?

Installation is straightforward: the set ships with instructions and necessary harnesses so most installs are plug-and-play. An integrated anti-flicker circuit board helps prevent flickering without additional components on most vehicle electrical systems.

• Packaged with instructions and 4 wiring harnesses
• Integrated anti-flicker circuitry to stabilize light output
• Designed for a quick swap into existing mounting locations

Who is this for? If you drive a vehicle that uses 4x6-inch rectangular headlights — from over-the-road trucks (Kenworth, Peterbilt, Freightliner) to classic cars and light trucks (older Chevy models, Camaro RS, Blazer variants) — and you want a DOT-compliant LED upgrade that balances brightness, weather-resistance, and an easy fit, this four-pack is built for that use. It suits fleet owners, restoration enthusiasts, and everyday drivers seeking a longer-lasting, whiter light without major wiring modifications.
