MAYELLO 4x6 LED Headlights 4-Pack — DOT Sealed-Beam Hi/Lo, 4500/3000 lm, Plug-and-Play

MAYELLO 4x6 LED Headlights 4-pack are DOT-approved sealed-beam replacements that deliver bright hi/lo illumination, simple plug-and-play installation, and long service life for most vehicles with 4x6" headlight housings.

These MAYELLO 4x6 LED sealed beam headlights replace standard sealed-beam units with high-output LEDs, offering clearer roadway lighting and a durable, moisture-resistant construction. Each lamp provides 4500 lumens on high beam and 3000 lumens on low, inside a fully sealed aluminum housing designed to limit condensation and protect internal components. The set ships with four H4 (9003/HB2) harnesses for easy connection to existing sockets and includes dot approval for road legality in applicable regions.

How do these headlights improve nighttime visibility?

The LEDs concentrate more usable light onto the road than many stock sealed-beam bulbs, producing brighter high- and low-beam patterns for clearer sightlines. That makes it easier to see lane edges, signs, and obstacles without additional bulky accessories.

• 4500 lm on high beam and 3000 lm on low beam for strong illumination
• Distinct hi/lo beam pattern designed for sealed-beam housings
• White halo daytime running light and yellow halo turn-signal compatibility
• DOT-approved for on-road use in compliant jurisdictions

Are these lights easy to install on my classic car or truck?

Yes — the MAYELLO 4x6 LEDs are designed as direct replacements for most 4x6" sealed-beam units and use a standard H4 plug for straightforward wiring. Installation normally requires removing the old sealed beam and connecting the supplied harness without cutting factory wiring.

• Plug-and-play H4 (9003/HB2) harnesses included for each lamp
• Red wire powers the white halo daytime running light
• Green wire supports the yellow halo turn-signal function
• Fits sedans, trucks, and many classic models that accept 4x6" sealed beams

What construction and durability features do these headlights offer?

The housings use high-grade aluminum and a tightly sealed lens to reduce moisture entry and heat buildup, extending component life. An internal breather valve allows pressure equalization; if the lens fogs, opening that valve can quickly restore clarity without replacing the lamp.

• Aluminum housing for heat dissipation and corrosion resistance
• Sealed lens to protect LEDs from dust and moisture
• Advanced cooling system for up to 50,000 hours expected lifespan
• Breather valve cap to clear fogging when needed

Which vehicles are compatible with these sealed-beam headlights?

These 4x6" sealed-beam LED units are compatible with a wide range of vehicles that accept the 4x6" form factor. They are especially popular for classic cars and older trucks that use round or rectangular sealed beams, where modern LED performance is desired without housing modification.

• Fits up to 95% of vehicles with 4x6" sealed-beam openings
• Common fits: Chevy C10, K10, S10, Caprice, F-series trucks, Dodge Challenger/Charger/Dart, Chevrolet Chevelle/Corvette/Nova
