Buying Guide

Match the bulb socket

Confirm your vehicle's socket type (H4/9003, 9005/HB3, H7, H11/H9) to ensure plug‑and‑play fit and avoid adapter or wiring work

Check lumen output vs real-world beam

Higher lumen figures (e.g., 40k–100k listed) indicate raw output, but evaluate beam pattern and cutoff to avoid glare and ensure useful road illumination

Consider color temperature

6500K cool white is common for visibility and aesthetics, but higher Kelvin can appear blue and may affect contrast in rain or fog

Assess cooling and durability

Active fans or heat sinks extend LED life; look for specs noting cooling fans or robust housings to maintain long-term brightness

Compatibility with vehicle electronics

Some LED kits require harnesses or resistors for CANbus systems; verify LED harness compatibility if your car reports errors or flickers
