Main Features

1. High-Beam and Low-Beam Lighting

The headlights provide high- and low-beam functions for different driving conditions. Low beams are intended for regular nighttime driving, while high beams provide additional forward illumination when road conditions and traffic permit.

2. Integrated Daytime Running Lights

The built-in DRL function adds a modern appearance and can help make the vehicle more noticeable to other road users during daylight. Correct wiring and compatibility with the vehicle's electrical system are important for proper operation.

3. Four-Piece Headlight Set

The four-piece package can be useful for vehicles with multiple compatible rectangular headlight positions. Before ordering, confirm whether all four units are suitable for your vehicle's specific headlight arrangement and whether the set includes any necessary mounting hardware or wiring adapters.

4. Designed for Selected Older Vehicles and Trucks

The advertised fitment covers selected older passenger vehicles and heavy-duty truck applications. Since headlight housings, connectors, mounting brackets, and electrical requirements can vary considerably, checking the vehicle's model year and original headlight specifications is essential.

Performance

Performs exceptionally well for:

• Replacing compatible 4 × 6-inch rectangular headlights.

• Providing high- and low-beam lighting for nighttime driving.

• Adding daytime running light functionality to compatible vehicles.

• Refreshing the appearance of selected older cars and heavy-duty trucks.

Actual lighting performance depends on LED output, beam pattern, headlight alignment, wiring, and the vehicle's original mounting configuration. A compatible physical size alone does not guarantee correct optical performance or road legality.

Who Should Buy This?

Ideal for:

• Classic and older vehicle owners looking to replace compatible rectangular headlights.

• DIY automotive enthusiasts who want high/low-beam functionality and DRLs in a compatible headlight assembly.

Final Verdict

The BESTZHEYU 4PCS 4x6 LED Headlights offer a potentially useful lighting upgrade for vehicles that use compatible rectangular headlight assemblies. The combination of high and low beams, daytime running lights, and a four-piece package makes the set worth considering for selected older cars and trucks.

Before purchasing, verify the exact vehicle fitment, connector type, mounting dimensions, beam pattern, and road-use certification. Proper installation and headlight alignment are essential to achieve useful illumination without dazzling oncoming drivers.
