Direct replacement only: 1999-2000 NB1 versus 2001-2005 NB2, left versus right, connector/bulb and harness condition. The checked compatibility source flags 2005 wiring differences; confirm Mazdaspeed equipment separately. NA pop-up lamps are excluded.
OEM numbers
Checked NB1 references include left NC10-51-041C and right NC10-51-031C. No NB2 part number is published without exact authoritative confirmation.Supersession
No NB1-to-NB2 supersession is claimed. A facelift conversion is excluded because lamp shape, mounting and wiring details are a system change rather than direct replacement.
Fitment
Direct replacement only: 1999-2000 NB1 versus 2001-2005 NB2, left versus right, connector/bulb and harness condition. The checked compatibility source flags 2005 wiring differences; confirm Mazdaspeed equipment separately. NA pop-up lamps are excluded.
Aftermarket options
New OEM, used OEM and professionally retrofitted exact-core assemblies exist. Retrofit output and legality depend on the exact build; this page does not endorse an NB1/NB2 facelift conversion.
Before you buy
NB1 and NB2 lamps are not treated as direct substitutes. Confirm side, mounting, connector/bulb and harness, including the cited 2005 wiring caution and Mazdaspeed equipment. Facelift conversion instructions are outside this page.
