FAQ
Reader questions
How do I know which bulb size my 2013 Altima uses for low and high beams?
Check the owner's manual, the bulb socket label, or the door jamb placard for the 2013 Nissan Altima specifications; low beam typically uses 9006/H16 and high beam typically uses 9005/H8.
Can I upgrade to LED headlights in my 2013 Nissan Altima without changing the assembly?
Yes, you can replace halogen bulbs with LED bulbs in many cases, but verify fitment, cooling requirements, and local legality; some LED designs may require additional adapters or modified trim to avoid rattling.
Why do my new headlights look yellow or misaligned after replacement?
Misalignment or a yellow appearance can stem from incorrect bulb installation, failure to seat the assembly properly, or the need for lens cleaning; if alignment is off, recheck mounting points and aim the lights on a flat surface at night.
What should I do if the headlight warning appears after replacement?
Inspect the connector for damage, ensure proper bulb wattage and seating, clear any error codes with a scan tool if required, and confirm that the headlight level sensor is functioning; persistent warnings may require dealer diagnostics for adaptive systems.
