Questions
Does the 2022 Acura TLX chart include fog lights?
No fog-light bulb is stored for this year. This page does not add one.
What turn-signal bulb does the Acura TLX use?
Halogen-configuration turn signals in 2022 store 7440. An LED-headlight configuration can list LED instead of these bulbs.
Can I substitute a nearby bulb number?
No. H11 and H11B stay different. 9005 and 9006 stay different. This page matches the stored designation and does not swap in another bulb to fill the product list.
Does a catalog match guarantee the bulb fits?
A designation match means the product is filed under that bulb number and technology. It does not prove the lamp, socket, or vehicle configuration. Check the bulb in the housing before ordering.
How do I verify the replacement?
Read the number on the bulb or the housing, confirm whether the headlights are halogen, HID, or LED, and match that designation. Position names that say “with halogen headlights” or “with LED headlights” are separate configurations.
Does the Acura TLX bulb chart change by year?
