2Pcs 4x6in Car LED Headlights Vehicle Rectangular Headlamp With H4 Socket H4-to-3Pins Adapter With High Low Beam White Light IP68 Waterproof For 10-80V SUV Truck Sedan Car Motorcycle

Dim, yellowed sealed-beam headlights are a liability — on backroads, job sites, and highways alike. These 4x6 inch LED headlights deliver the crisp, bright white illumination your truck, SUV, van, or motorcycle deserves, with a genuine plug-and-play H4 socket connection that means zero cutting, zero splicing, and zero headaches. The 4x6-inch rectangular sealed-beam format is one of the most common headlight sizes in American automotive history, fitted across several decades of domestic and imported vehicles. This 2-piece kit is engineered as a universal drop-in replacement for any vehicle that accepts a standard 4x6 inch rectangular headlight housing. Well-known applications include Ford F-Series trucks (F-100 through F-350 classic generations) and the Ford Bronco, Chevrolet and GMC C/K full-size pickups, Jeep Cherokee XJ and Wrangler YJ models, Dodge Ram and D-Series trucks, various medium-duty box trucks, commercial cargo vans, agricultural tractors, off-road vehicles, and motorcycles. The included H4-to-3-pin adapter extends compatibility to vehicles using a 3-pin connector configuration without requiring any wiring modification. Always confirm your vehicle's housing dimension and connector type before ordering to ensure proper fit. • Bolt-In Brightness: The H4 socket design means installation takes minutes — plug directly into your factory wiring harness on H4-equipped vehicles, or use the included H4-to-3-pin adapter for 3-pin systems. No modifications needed. • True Dual-Beam Performance: High beam and low beam are both integrated into a single compact LED unit. You get full headlight functionality — bright highway highs and properly aimed lows — without sourcing or managing separate bulbs. • Wide Voltage Compatibility: Operating range of 10V to 80V DC makes these headlights equally capable on 12V passenger cars, 24V diesel commercial trucks, 36V–48V specialty equipment, and agricultural machinery. One SKU covers an enormous range of applications. • IP68 Waterproof Rating: The dust-tight, submersion-proof IP68 housing stands up to rain, car washes, road spray, mud, and off-road stream crossings. These are built to work in real-world conditions, not just a dry garage. • Crisp White Output: The LED light color is clean white, improving road visibility and object contrast compared to the warm yellow cast of aging sealed-beam halogen units. Better visibility means safer driving. • Compact Sealed Design: The 4x6-inch rectangular form factor fits directly into OEM headlight bucket housings without any adapters for the housing itself — only the wiring side may require the included adapter. • Headlight Size: 4 x 6 inches (rectangular sealed-beam footprint) • Beam Type: Dual — high beam and low beam integrated in one unit • Connector: H4 socket; H4-to-3-pin adapter included • Operating Voltage: 10V – 80V DC (compatible with 12V, 24V, 48V systems) • Light Color: White (6000K-range LED output) • Waterproof Rating: IP68 (dust-tight and submersion-rated) • Quantity: 2 pieces per kit (driver and passenger side) • Application: Universal — trucks, SUVs, sedans, motorcycles, commercial vans, agricultural equipment The housing on these 4x6 LED headlamps is constructed from high-impact polycarbonate, the same material class used in modern OEM automotive lens applications for its strength-to-weight advantage and resistance to UV degradation. Unlike older glass sealed-beam units that yellow and cloud over years of sun exposure, the polycarbonate construction retains optical clarity for the life of the LED emitters. The rear connector housing is precision-molded to achieve a positive, weather-tight seal at the H4 socket interface, reinforcing the IP68 rating at every potential ingress point. The die-cast aluminum or reinforced composite heat sink integrated into the back of the assembly manages LED operating temperatures efficiently, preventing the thermal throttling that shortens the life of lower-grade LED headlights. The result is a robust, road-ready headlight assembly that holds up to daily commercial driving, trail use, and farm field conditions with equal reliability. Installing these 4x6 LED headlights is straightforward and requires only basic hand tools. Step 1: Gather your tools — typically a Phillips or flathead screwdriver, a trim panel remover if needed, and optionally a socket set for headlight retaining ring bolts. Step 2: Open your hood and disconnect the negative terminal of your battery as a precaution before handling any electrical connections. Step 3: Remove the headlight retaining ring screws or clips on your existing sealed-beam headlight. Carefully pull the housing forward and unplug the factory connector from the back of the sealed beam. Step 4: Identify your connector type. If your vehicle has a standard H4 two-wire-plus-ground plug, connect it directly to the H4 socket on the new LED unit. If your vehicle uses a 3-pin connector configuration, attach the included H4-to-3-pin adapter to the LED unit first, then plug in your factory harness — still no cutting required. Step 5: Seat the new 4x6 LED headlight into the housing bucket, ensuring it is oriented correctly (many rectangular housings are keyed). Reattach the retaining ring and screws. Step 6: Reconnect your battery, then test both high beam and low beam functions before final tightening. Step 7: Perform a basic aim check — point your vehicle at a flat wall at approximately 25 feet and confirm the beam pattern is level and not blinding oncoming traffic. Adjust the headlight aim screws if your housing provides them. • 2x 4x6 inch LED headlight assemblies (driver and passenger side) • 2x H4-to-3-pin wiring adapters • Mounting hardware (retaining ring compatibility depends on vehicle) At Expedite Auto Parts, we stock real-world truck and commercial vehicle parts — no filler, no fluff.
