Fitment advice: This is the right-hand rear lamp for applicable Mazda MX-5 ND soft-top and RF models from 2015–2023. It is not the left-hand lamp.

Model-year advice: Revised rear lighting was introduced for the later 2024-onward facelift in some markets. Do not assume that N243-51-150G fits an ND3 vehicle without confirming the original lamp reference.

Reference advice: N243-51-150E and N243-51-150F are earlier references associated with the same right-rear lamp position. N243-51-150G is the later supplied revision.

Gasket advice: Mazda catalogue data indicates that the lamp-to-body gasket may be included with the complete lamp assembly. Check the supplied Mazda packaging before purchasing or listing a separate gasket.

Moisture advice: Where the original lamp contains water or excessive condensation, inspect the body aperture, lamp gasket, wiring entry and surrounding drainage area before fitting the replacement.

Electrical advice: Inspect the vehicle-side connector and wiring loom for corrosion, damaged terminals, trapped wiring or poor electrical contact. A vehicle-side electrical fault can produce symptoms similar to a defective lamp.

Bodywork advice: Confirm that the rear quarter panel and lamp mounting points are correctly aligned. Installing the lamp against distorted bodywork can stress the housing or prevent the gasket from sealing correctly.

Fastener advice: Tighten the mounting fasteners evenly and only to the specified torque. Excessive tightening can crack the housing, damage the studs or distort the lamp-to-body gasket.

Function check: Test the rear position lamp, brake lamp, direction indicator and reversing lamp after installation. Check the corresponding functions on the opposite side at the same time.

Other items to consider: Consider inspecting the lamp-to-body gasket, mounting nuts, wiring connector, luggage-compartment trim clips and surrounding body seals according to their condition.

Useful tools / consumables: Trim-removal tools, suitable sockets, low-range torque wrench where appropriate, electrical-contact cleaner and clean lint-free cloths.

Difficulty guide: DIY Difficulty: Moderate. Access is required behind the luggage-compartment trim, and care is needed to avoid damaging the lamp housing, paintwork, wiring or sealing gasket.

Why Genuine Mazda? Genuine Mazda rear lamps are manufactured to the original lens pattern, housing profile, mounting geometry, electrical connections and body-sealing arrangement. Using the correct OE assembly helps retain the intended appearance, light distribution and fit against the rear body panel.

What’s in the box: One Genuine Mazda right-hand rear combination lamp assembly, part number N243-51-150G. The left-hand lamp, external mounting hardware, luggage-compartment trim and installation tools are not included unless specifically shown or stated separately.

Installation notes: Switch off the vehicle lighting and disconnect the battery where required. Remove the appropriate luggage-compartment trim, disconnect the lamp wiring and remove the mounting fasteners. Withdraw the original lamp carefully without levering against the painted bodywork. Inspect and clean the mounting aperture and sealing gasket, connect and position the replacement assembly, then tighten the fasteners evenly. Refit the trim and test every rear-lighting function before returning the vehicle to service.
