Buying Guide: How to Choose the Right 4×6 LED Headlights
- Compatibility: Confirm the 4×6 inch sealed-beam mounting hole on your vehicle and whether your wiring harness requires adapters or resistors.
- Brightness: Look for lumen ratings and beam pattern. Higher lumens provide better distance visibility, but ensure the beam is properly focused to avoid glare for oncoming drivers.
- Durability: Consider IP rating, housing material (aluminum preferred), and heat dissipation design to minimize moisture buildup and prevent dimming over time.
- Color Temperature: 6000K is common for white light; evaluate whether you prefer a cooler white for contrast or a warmer white for color rendering in your conditions.
- Power and Electrical Fit: Check voltage range (DC 9-36V commonly) to ensure compatibility with your vehicle’s electrical system and whether load resistors are needed for turn signals or DRLs.
- Legal & Safety: Ensure DOT/SAE approvals if you operate on public roads in your region. Verify that any halo or DRL features comply with local regulations.
- Installation: Assess whether mounting brackets, wiring harnesses, and sealants are included. Some sets require modifications or additional hardware.
