  • โ†’Replace bulbs in pairs โ€” if one side burned out, the other is likely near end of life

Frequently Asked Questions

What size headlight bulb does a Infiniti M56 use?
The Infiniti M56 headlight bulb size varies by year. Newer models often use factory LED units, while older models use H11, H7, or 9006 halogen bulbs. Check the year-specific specs below for your exact fitment.
Can I put LED bulbs in my Infiniti M56?
If your Infiniti M56 has halogen headlights, you can install LED replacement bulbs. Look for bulbs with a proper beam pattern (projector-compatible) to avoid blinding other drivers. Some models may need anti-flicker adapters.
How do I replace the headlight bulb on a Infiniti M56?
On most Infiniti M56 models, you can access the headlight bulb from behind the headlight assembly in the engine bay. Twist the bulb socket counterclockwise, pull out the old bulb, insert the new one (don't touch the glass), and twist back in.
Why does my Infiniti M56 headlight keep burning out?
Frequent bulb burnout on the Infiniti M56 is usually caused by a loose connection, moisture in the housing, touching the bulb glass during installation, or a voltage regulator issue. Check the connector and housing seal.
