What you need to know
Water-test before ordering. Inspect lamp cracks/studs, lamp gasket, third brake lamp, rain rail, antenna drain, body seams and battery vent as applicable.
OEM numbers
Checked NA lamp-to-body gasket NA01-51-158, two required per car. NB gasket/washer construction is different and must be matched to the NB lamp/catalog.Supersession
No NA-to-NB lamp or gasket interchange is asserted. Left/right assemblies are distinct; the NA gasket number is not generalized to NB.
Fitment
Water-test before ordering. Inspect lamp cracks/studs, lamp gasket, third brake lamp, rain rail, antenna drain, body seams and battery vent as applicable.
Aftermarket options
New OEM/aftermarket gaskets and used complete lamps exist. Reusing hardened gaskets or applying uncontrolled sealant can complicate later service.
Before you buy
NA and NB gasket arrangements differ, and left/right lamps are not interchangeable. Water-test first because rain rail, third brake light, antenna drain, seams or battery vent can mimic a tail-lamp leak.
