Product Details
Replace a tired four-headlight setup in one order. This four-lamp set gives compatible semi-trucks and classic vehicles a matching 4×6 front-lighting upgrade instead of mixing old housings with single replacement lamps. Use the 3,000LM low beam for regular night traffic and switch to the 6,000LM high beam on dark highways and rural roads. Built-in DRL and turn signal functions add the lighting modes needed for daytime routes, frequent stops and busy turns. The DC 9–32V input works with compatible 12V and 24V vehicle systems, while black and silver bezel options make it easier to match the vehicle’s front end.
Replace a Mixed Four-Lamp Setup in One Order
Older four-headlight vehicles are often repaired one lamp at a time. After several replacements, the front end may have different bezel colors, different lens conditions or lamps with uneven output. This package includes four matching 4×6 LED headlights, so you can replace the full set together. The finished vehicle gets one consistent headlight style instead of a mix of old and new lamps. This is especially useful for semi-truck restorations, classic-car upgrades and fleet vehicles that need the same appearance across several units.
Low Beam for Traffic, High Beam for Dark Highway Miles
A delivery route, an interstate run and a rural road do not need the same light mode. Use the 3,000LM low beam when driving through regular traffic, loading areas or city streets. Switch to the 6,000LM high beam when the road becomes darker and more open. You do not have to depend on one light level for every part of the route.
DRL and Turn Signal for Frequent Stops and Turns
City delivery trucks, work vehicles and classic cars used in traffic make frequent turns and lane changes. A basic high/low headlight does not provide the same range of front-lighting functions. These 4×6 LED headlights add DRL and turn signal modes to the high and low beams. You get the functions needed for daytime routes, nighttime driving and turn indication in the same rectangular housing.
A Practical Choice for 12V and 24V Vehicle Groups
Stocking separate headlight versions for passenger vehicles and heavy trucks creates more SKUs, more packaging and more inventory to manage. The DC 9–32V input covers compatible 12V and 24V electrical systems. A distributor can use one core model across several classic-car, pickup and semi-truck product groups, provided the mounting position, wiring and connector are confirmed before ordering.
Keep the Classic 4×6 Shape Without Keeping the Dated Look
Many older trucks and classic cars depend on the rectangular shape as part of the grille design. Changing to a different headlight format can make the front end look out of place or require extra mounting work. This model keeps the compact 4×6 shape while adding a modern LED face and four lighting modes. Choose the silver bezel for a more traditional appearance or the black bezel for a darker custom build.

Fitment Check Before Ordering
A matching model year does not guarantee installation by itself. Before ordering, confirm:
• The existing headlight position uses a 4×6 rectangular lamp.
• The vehicle uses two or four headlights.
• The high-beam and low-beam positions match the required lighting functions.
• The connector and pin layout match the vehicle wiring.
• The retaining ring or mounting bracket fits the lamp housing.
• There is enough clearance behind the lamp.
• DRL and turn signal wiring can be connected to the vehicle.
