Genuine Mazda Pop-Up Headlamp Cover / Lid – LH • NA01-51-SH2B

Genuine Mazda Pop-Up Headlamp Cover / Lid – Left Hand

Replacement Genuine Mazda left-hand pop-up headlamp cover for all Mazda MX-5 Mk1 NA models equipped with the factory retractable headlamp system.

This exterior panel fits to the top of the left-hand pop-up headlamp assembly. When the headlamp is lowered, the lid sits within the bonnet opening and forms part of the vehicle’s exterior body surface. It rises with the complete headlamp pod when the lights are operated.

The panel is supplied in primer ready for final preparation and painting to match the vehicle. It is separate from the internal black headlamp vessel, lamp unit, retaining ring, mounting frame, hinges and electric retractor mechanism.

One left-hand lid is fitted per vehicle, and this listing supplies one Genuine Mazda headlamp cover. The corresponding right-hand lid is supplied separately under Mazda reference NA01-51-SH1B.

Side identification: Left hand refers to the vehicle’s left side when seated in the vehicle facing forwards. On a UK right-hand-drive MX-5, this is the nearside or passenger side.

Typical reasons for replacement:

• Panel damaged following front-end impact
• Corrosion affecting the lid or mounting points
• Lid no longer sitting flush with the bonnet
• Paint finish badly faded, chipped or deteriorated
• Mounting points cracked or damaged
• Original lid missing following previous repairs
• Headlamp pod being restored or rebuilt

Fitment advice: NA01-51-SH2B is the left-hand exterior headlamp lid. It should not be confused with NA01-50-751, which is the separate black internal vessel fitted around the left-hand headlamp unit.

Painting advice: Trial-fit and align the panel before final paintwork. Complete the necessary surface preparation, priming and colour matching using products suitable for automotive exterior panels.

Alignment advice: The lid must sit evenly within the bonnet opening when lowered and clear the bonnet, internal vessel and surrounding bodywork throughout the complete raising and lowering cycle.

Replacement advice: Inspect the headlamp mounting frame, lid brackets, hinges, lifting rod and retractor mechanism before installing the new panel. A replacement lid will not correct a bent frame or worn lifting mechanism.

Electrical safety: Isolate the retractable headlamp system before working around an open headlamp pod. The assembly can move unexpectedly if the mechanism remains energised.

Other items to inspect: Check the internal left-hand vessel, lamp retaining ring, adjustment hardware, lifting linkage, electrical connectors and the corresponding lid on the opposite side.

Useful tools / consumables: Small socket and spanner set, screwdrivers, plastic trim tools, masking materials, automotive primer, colour-matched paint and corrosion-protection products as required.

Difficulty guide: DIY Difficulty: Moderate. Mechanical installation is relatively straightforward, but careful panel alignment and professional-quality paint preparation may be required.

Why Genuine Mazda? Genuine Mazda headlamp lids match the original panel shape, bonnet aperture, mounting positions and retractable-headlamp geometry. Correct dimensions help the panel sit flush when lowered and move without contacting the surrounding bodywork.

What’s in the box: One Genuine Mazda left-hand pop-up headlamp cover / lid, part number NA01-51-SH2B.

Installation notes: Raise the headlamp and isolate the retractor system before removing the original lid. Record the position of the mounting brackets and adjustment points. Trial-fit the replacement panel before painting, then transfer reusable brackets and hardware as required. Adjust the lid so that its height and panel gaps match the bonnet when lowered. Operate the headlamp through several complete cycles and confirm that the lid does not contact the bonnet, vessel or surrounding bodywork.
