Buying Guide
What matters most when choosing H4/9003 headlights?
- Brightness: Higher lumens deliver more forward visibility, but may increase power draw and heat. Compare paired lumens (per set) rather than per bulb.
- Beam pattern: Look for 1:1 or halogen-matched shapes to maintain familiar lighting behavior and reduce glare for oncoming drivers.
- Heat management: Turbo or high-speed cooling fans and aluminum housings lengthen bulb life in hot conditions.
- Durability: IP68/IP67 ratings indicate strong water resistance; this matters in rain or snow.
- Installation: Plug-and-play designs save time and avoid extra wiring; verify compatibility with your vehicle’s sockets and housing size.
- Electrical compatibility: Some cars require CANBUS compatibility to avoid warning lights; check the product’s notes for fitment.
