BICYACO 4x6 Inch LED Headlights 4-Pack — 6500K High/Low Beams, IP67 Waterproof

BICYACO 4 PCS 4x6 inch DOT-compliant LED headlights deliver bright 6500K white high/low beams with IP67 waterproofing and plug-and-play wiring for classic trucks and older cars.

Upgrade worn or dim rectangular headlights with this four-piece set engineered for heavy-duty trucks, commercial rigs and vintage vehicles that use standard 4x6 H4651/H4652-style lamps. Each lamp uses efficient 60W LED output, an aluminum alloy housing for faster heat dissipation, and a built-in anti-flicker circuit so installation is straightforward and lighting is stable. With a sharp cut-off for reduced glare and a long rated service life, these lights modernize visibility while fitting common factory housings.

What lighting performance can I expect from these 4x6 LEDs?

These BICYACO units produce a pure white 6500K light that improves perceived contrast and roadside visibility. They include both high- and low-beam functions with a defined beam pattern designed to reduce glare for oncoming drivers.

• 60W total power per headlight for strong illumination
• 6500K color temperature for crisp white light
• High/low beam beams with sharp cut-off for controlled spread
• Integrated anti-flicker circuit for steady output on varied electrical systems

How durable and weatherproof are these headlights?

Built for road use, the lamps have an IP67 waterproof rating to resist rain, splashes and brief immersion. The aluminum alloy housing and heat-dissipating design extend longevity and help maintain brightness over time.

• IP67 rated for reliable wet-weather operation
• Aluminum alloy body and fins for efficient heat management
• Rated life up to 50,000 hours under normal use
• Cold-weather tested to minimize failures in low temperatures

Will these fit my vehicle and how hard is installation?

These lamps are made to replace standard 4x6 rectangular units (H4651/H4652/H4656/H4666/H6545 form factors) and work with many trucks, SUVs and older cars. The kit is plug-and-play and ships with H4/9003/ HB2 wiring harnesses so you can complete installation quickly.

• Compatible with common 4x6 housings used by Peterbilt, Kenworth, Freightliner and many GM models
• Ships with four H4 (9003/HB2) wiring harnesses and instructions
• Typical install time around 20 minutes per lamp with basic tools
• Anti-flicker electronics integrated—no extra modules required

How do these headlights protect other drivers from glare?

The optics produce a clean, crisp cut-off line on low beam so light is directed onto the road rather than into oncoming eyes. That controlled beam pattern helps improve your vision without increasing discomfort for other drivers.

• Defined low-beam cutoff prevents excessive upward scatter
• Wide, even spread on high beam for improved peripheral illumination
• Engineered to meet DOT-compliant specifications for road use in the U.S. and Canada

Who this is for: Drivers of older trucks, commercial rigs and classic vehicles who need a reliable, brighter replacement for worn 4x6 rectangular headlights will benefit most from this BICYACO four-pack. It’s suited to fleet maintenance shops, owner-operators and DIY mechanics who want faster installs, weatherproof performance and a long-lived upgrade that fits standard housings on Peterbilt, Kenworth, Freightliner models and many GM cars and trucks.
