Best 4X6 Sealed Beam Headlights for Classic Vehicles and Trucks

#1 · Best Overall

1. Morimoto Sealed4

• Lens Material: Polycarbonate
• Wattage: 35 W
• Voltage: 12 V DC
• Compatible with Vehicle Type: Bus, Car, RV, Truck, Van

Best for: Precision-optics classic LED buyers.

Why it ranks #1: The DOT-approved pair lists up to 4,300 high-beam lumens, projector optics for low beam, broad vehicle compatibility, and a five-year manufacturer warranty.

Morimoto’s Kuria Optic projector lens shapes the low-beam pattern, giving this DOT-approved 4-by-6-inch LED pair a named optical feature beyond basic lamp replacement. High beam is listed at up to 4,300 lumens, and die-cast housings double as heat sinks for longevity.

The Kuria Optic projector lens is specified for low-beam precision, giving buyers a defined beam-control feature for regular road use. High-beam output reaches up to 4,300 lumens, while die-cast housings also function as heat sinks, linking the housing construction to heat management. The pair includes universal wiring and is listed for cars, trucks, buses, RVs, and vans with 4-by-6-inch headlights, giving installers wiring components across varied vehicle categories.

Skip it if you prioritize a higher listed wattage; MAYELLO 4Pcs 4×6 LED Headlights specifies 60 watts.

This pair suits drivers seeking a 4-by-6-inch LED upgrade with a projector low beam, high-beam output, and included universal wiring. It is listed at 35 watts, a relevant boundary when comparing electrical specifications.

#2 · Best Plug-and-Play

2. Holley RetroBright

• Lens Material: Polycarbonate
• Compatible with Vehicle Type: Car

Best for: Classic-car LED upgrade seekers.

Why it ranks #2: This LED headlight plugs into the factory harness, claims over twice halogen output, and has a glare-conscious SAE- and DOT-compliant beam pattern.

Plug-and-play connection to a factory headlight harness lets this 4-by-6-inch LED upgrade install without a described wiring conversion. Its 5700K Modern White output keeps a retro-styled appearance while supplying more than twice the light output of halogen, aimed at classic-car owners seeking newer lighting technology.

The factory-harness plug-and-play connection simplifies installation for compatible classic sealed-beam systems, while the classic styling preserves a period-correct look. Holley lists more than twice halogen light output and a no-glare beam pattern that meets or exceeds SAE and DOT requirements, so the upgrade targets visibility without abandoning beam compliance. Lower current draw and six-times halogen life affect ongoing use; replaceable LED cartridges also make later service more direct than replacing the entire headlight.

Skip it if you need two lamps in one order; Morimoto Sealed4 LF267 is listed with a pair of headlight assemblies.

A practical choice for classic-car owners upgrading a compatible 4-by-6-inch sealed-beam system who want modern white LED light and serviceable cartridges. It is sold individually, so account for that when replacing both headlights.

#3 · Best Output Details

3. Partsam 4×6 LED

• Lens Material: Polymethyl methacrylate
• Wattage: 45
• Voltage: 12 V
• Compatible with Vehicle Type: Universal

Best for: Broad-fit truck LED conversion.

Why it ranks #3: The two-piece LED set specifies 5,600 high-beam and 2,500 low-beam lumens, H4 compatibility, and claimed fit across many vehicle types.

High- and low-beam outputs are specified separately at 5,600 and 2,500 lumens, giving this 4-by-6-inch Partsam LED pair distinct beam functions. Its listed compatibility spans heavy-duty trucks and many cars, while built-in EMC and anti-flicker measures target electrical interruptions and error-code concerns.

The H4651, H4652, H4656, H4666, and H6545 compatibility identifiers help buyers match this headlight to listed sealed-beam types; the product also states fitment for numerous truck and car applications. Separate high- and low-beam lumen figures clarify its two operating modes. Osram LED chips and built-in EMC/anti-flicker features are presented as ways to improve illumination and address flickering or error codes, while the waterproof, sealed construction suits exposed headlight locations.

Skip it if you want a glass halogen conversion set; Parts N Go PNG-4652B includes glass housings and H4 bulbs.

This pair suits owners of listed cars or heavy-duty trucks replacing a compatible 4-by-6-inch sealed-beam setup with LED high/low lighting. Its broad fit claims still depend on matching the vehicle's specified headlight type.

Four 4-by-6-inch LED headlights deliver listed outputs of 4,500 lumens on high beam and 3,000 on low beam, making this MAYELLO set suited to systems using four rectangular lamps. Aluminum housings and sealed lenses are specified to address condensation and moisture exposure.

The four-piece quantity suits vehicles using a four-headlight arrangement, while the separate high- and low-beam lumen figures clarify the listed output for each mode. MAYELLO identifies compatibility with trucks including Freightliner FLD, Peterbilt 379 and Kenworth W900 models, along with several older passenger vehicles. Aluminum housings are described as helping avoid water condensation underneath, and sealed lenses are intended to keep moisture out, relevant to continued outdoor use.

Skip it if you need a two-lamp pair; Morimoto Sealed4 LF267 is listed with two headlight assemblies.

5. TRUE MODS 4×6 LED

• Lens Material: Polycarbonate
• Wattage: 28.8 W
• Voltage: 12 V
• Compatible with Vehicle Type: Car, SUV, Truck

Best for: Truck owners wanting paired LEDs.

Why it ranks #5: The two-piece H4 LED set lists 12-volt operation, a pre-attached pigtail connector, and IP67 water- and dust-intrusion protection.

A pre-attached five-inch H4 pigtail connector gives this two-headlight LED set a direct connection point for compatible H4 wiring. Its 4-by-6-inch 2A1 format is identified for Peterbilt and Kenworth applications, combining high- and low-beam function with a rugged polycarbonate lens and heavy-duty housing.

The H4 socket plug and attached five-inch pigtail support a straightforward connection workflow, while the listed 12-volt specification defines the electrical system. High/low-beam operation combines both functions in each 4-by-6-inch headlight, avoiding the need to select separate beam versions. The polycarbonate lens and heavy-duty housing are listed alongside IP67 water- and dust-intrusion standards, making the set relevant to truck owners whose headlights face exposed operating conditions.

Skip it if you prioritize a listed 60-watt set; MAYELLO 4Pcs 4×6 LED Headlights specifies 60 watts.

Consider this pair for a compatible Peterbilt or Kenworth 4-by-6-inch setup needing H4 high/low LED headlights and a short pre-attached lead. Check that the five-inch pigtail suits your installation routing.

6. BAOLICY 4×6 LED

• Lens Material: Polymethylacrylate
• Wattage: 180 W
• Voltage: 36 V DC
• Compatible with Vehicle Type: Compatibility with Volvo…

Best for: Four-lamp plug-and-play LED conversions.

Why it ranks #6: This four-piece LED set lists high and low beams, an H4 socket, and IP68 sealing, though its specifications give a 36-volt rating.

Four 4-by-6-inch LED headlights with standard H4 sockets provide a plug-and-play connection for compatible sealed-beam systems. BAOLICY lists high and low beams in the same lamp, plus an IP68 sealed cover, aluminum housing, and ribbed heat-sink fins for moisture protection and cooling.

#7 · Best Glass Conversion

7. Parts N Go Halogen Set

• Lens Material: Glass
• Wattage: 55 W
• Voltage: 12 V
• Compatible with Vehicle Type: Car, Truck

Best for: Classic halogen conversion restorers.

Why it ranks #7: The conversion set includes four glass-lens replacements and four H4 halogen high/low-beam bulbs for H4656 and H4651 applications.

Four glass-lens conversion headlights and four ultra-white H4 high/low halogen bulbs make this Parts N Go set a complete multi-lamp replacement package. The removable bulb sockets let owners change bulbs separately from the housings, while H4656 and H4651 compatibility targets cars and trucks from 1976 to 1992.

The four 4-by-6-inch glass housings pair with four H4 bulbs, giving buyers the components for a multi-headlight conversion rather than requiring a separate bulb purchase. Removable bulb sockets support bulb replacement without treating the housing and lamp as one sealed unit. The stated H4656 and H4651 applications and 1976–1992 vehicle range help narrow fitment; the included small blue City Light bulb illuminates the sealed housing as an additional listed function.

Skip it if you want LED headlights; Holley RetroBright LFRB140-1 is a plug-and-play 4-by-6-inch LED option.

Choose this set for a classic car or truck conversion where glass housings, replaceable H4 halogen bulbs, and four lamps suit the setup. Its listed vehicle range is 1976 to 1992, so fitment outside that range needs particular care.

8. YLT AUTO Semi-Sealed

• Lens Material: Polycarbonate
• Wattage: 55 W
• Voltage: 12 V
• Compatible with Vehicle Type: Car

Best for: H4 bulb-system replacement buyers.

Why it ranks #8: This pair uses a 4×6 format, lists 55-watt, 12-volt operation, and has a transparent lens and waterproof feature.

A semi-sealed 4-by-6-inch format accommodates H4 HID, LED, or halogen replacement bulbs, giving buyers flexibility to choose a bulb type rather than commit to a single listed light technology. The pair is specified for 12-volt, 55-watt use and has a waterproof feature for car applications.

The 4-by-6-inch square format identifies the intended headlight size, while the H4 replacement design supports several bulb technologies named in the title. That combination suits buyers who want to retain a familiar rectangular headlight footprint while selecting HID, LED, or halogen bulbs. The product is sold as a pair, and its listed 12-volt, 55-watt specifications help define the electrical requirements. A waterproof feature is also listed, relevant to headlights exposed to outdoor conditions.

Skip it if you need a fully sealed-beam assembly; Parts N Go PNG-4652B is listed as a glass-housing conversion set.

Choose this pair if you need a 4-by-6-inch semi-sealed replacement and value the option to use H4 HID, LED, or halogen bulbs. Its semi-sealed construction is the key boundary when shopping for a complete sealed-beam unit.

#9

9. GP Thunder Glass Pair

• Lens Material: Glass
• Compatible with Vehicle Type: Van

Best for: Glass-lens sealed-beam traditionalists.

Why it ranks #9: The pair has glass lenses and lists H4651, H4652, H4656, H4666, and H6545 replacements, but vehicle compatibility is limited in the supplied details.

A glass lens distinguishes this 4-by-6-inch GP Thunder pair for buyers keeping a traditional sealed-beam setup. The product lists H4651, H4652, H4656, H4666, and H6545 replacements and H4 bulbs, making it a glass-lens option for selected vans and other listed vehicle applications.

The glass lens preserves a conventional material choice for owners replacing sealed-beam headlights, and the H4 bulb specification identifies the bulb format. Listed replacement identifiers—H4651, H4652, H4656, H4666, and H6545—give a concrete starting point for matching the existing unit. The pair quantity covers two headlight positions, while the manufacturer notes fitment on some vans, Hondas, Nissans, and Mazdas rather than claiming universal compatibility.

Skip it if you need a broadly listed truck fit; Partsam GTCV-0565570344 names heavy-duty truck and car applications.

A suitable candidate for buyers who want glass-lens replacements and can match one of the listed sealed-beam identifiers. The fitment description is limited to some vehicle applications, so it is not presented as a universal choice.

#10

10. United Pacific 31390

• Lens Material: Glass
• Wattage: 55 W
• Voltage: 12
• Compatible with Vehicle Type: Car, Truck

Best for: Single high-beam glass replacements.

Why it ranks #10: This 4×6 glass-lens lamp is a single high-beam unit, so it is less complete for buyers seeking a full replacement pair or high/low-beam setup.

A reinforced reflector and rugged anti-vibration construction distinguish this United Pacific 4-by-6-inch glass headlight for buyers replacing a high-beam unit. It is a single high-beam assembly, with DOT/SAE designation and 55-watt, 12-volt specifications for compatible car and truck applications.

The glass lens and reinforced reflector provide the construction details for buyers maintaining a conventional rectangular headlight assembly. Rugged anti-vibration construction is relevant to vehicles exposed to movement, while the DOT/SAE designation identifies the listed compliance description. The 55-watt, 12-volt specifications help define electrical requirements, and the car-and-truck compatibility listing gives a broad vehicle category; the high-beam-only designation is important when planning the replacement.

Skip it if you need both beam functions in one headlight; BAOLICY 4×6 Inch LED Headlights lists high and low beam together.

Pick this single assembly when replacing a compatible 4-by-6-inch high-beam headlight and retaining a glass lens. It does not provide a pair or combined high/low function, so plan around that specific role.
