Buying Guide

Match the bulb fitment

Confirm your vehicle's OEM bulb type (H4/9003, 9005/HB3, H7, H11, etc.) to ensure plug-and-play compatibility and avoid wiring modifications

Check lumen output and kelvin

Compare lumen ratings and 6500K color temperature for relative brightness and cool-white tone; higher lumens usually indicate more output but consider beam pattern too

Assess cooling method

Look for active cooling fans or upgraded heat-sink designs—products listed use cooling fans or enhanced thermal designs to maintain performance and lifespan

Consider harness and CAN compatibility

Ensure LED kits are compatible with your vehicle's electronics or include an LED harness/decoder to prevent flicker, error codes, or CAN-bus issues

Evaluate multi-bulb kits and packaging

Decide if you need single-pair bulbs or multi-pack kits (some options come as 4-pack sets) to outfit both headlights and fog lights for consistent color and output
