LATER NORTH-AMERICAN LAMP / UNREGISTERED BODY POSE
Rear lights with
separate service boundaries.
Tall lamp-body and lens references replace the broad red blocks and separate circles embedded in the old body shell. Rear studs, seals, bulb chambers, hollow holders and short local lead bundles now expose the mounting and access relationships. The fitted lamp identity and body registration remain unverified.
Keep the market and lamp family explicit
Factory parts plate 213 lists the later USA/Canada BHA5260 assembly and 37H7119 lens, distinct from BHA4973/37H4737. The modeled reference has red above amber and an integral red reflex zone, as shown by the supplier's front, open-base and rear photographs. Those photographs show an offered reproduction. IMG_6329/6341 give owner rear-quarter context without identifying the fitted complete rear lamp.
The three colored optical volumes share one selectable lens record per side. Their colors do not make them three removable service pieces. The supplier pictures support two bulb chambers, two front lens screws and two rear stud roles, without calibrating their dimensions or the car's hole map.
| Reference boundary | What is supported; what remains unknown |
|---|---|
| Cast base / rear-quarter body | Separate base, unloaded body gasket, two stud/nut/washer roles and rear bulb-access windows. All sections, gauge, maps, seal compression, body receivers and mounting coordinates remain estimates. No body openings are cut to manufacture agreement. |
| One lens / base | One lens record with red, amber and integral reflex zones; separate unloaded seating frame and two front screw envelopes. Actual screw identity, optical construction, sealing and fitted lens type remain unknown. |
| Stop/tail and indicator bulbs | Factory GLB380/GLB382 roles; the separately attributed OSRAM 7528 P21/5W and 7506 P21W comparisons provide nominal 26.5 mm diameter and 52.5 mm length. Globe/neck/base breakdown is estimated; fitted manufacturer, bayonet keys, contact engagement and filaments are not reconstructed. |
| Rear holder / local wiring | Two hollow holder envelopes, separate boot comparisons and two short open lead-bundle envelopes. These are not an asserted conductor count, circuit, color/polarity map, earth path or complete rear harness. |
Use the boot surroundings without inventing an access path
The lamp center stations now use the conditional IMG_6329 pose documented in the shared rear-body reconstruction. Shape and 22-degree rake are held; only Y/Z were fitted under an explicit unmeasured lateral prior. Opposite-side symmetry is assumed. The 80 mm width, local height, 22-degree rake and all lamp/body sections remain unmeasured construction estimates. Rear-quarter curvature, receiving surfaces, body apertures, retention and the common installed pose still need reconciliation. The boot lid follows the revised shared profile. Rear bumper and rear wheelhouse/shackle sources stay unchanged. Lamp-body seats and apertures remain unresolved.
Use isolation to inspect a lens, base, holder, bulb or fixing role, then return to the whole car for the surrounding body and boot. These offsets do not establish release order, supported access, bulb twist/withdrawal travel, wiring disconnection, tightening or a verified lamp replacement path. Do not drill, cut or choose parts from this drawing. Reverse lamps, rear side markers and number-plate lighting remain separate incomplete assemblies.
Validation covers valid connected bases, native STEP round-trip, positive mesh volumes, open bulb passages, selected lens/base/seal nonintersections and rear-bumper source comparison. These checks establish reference geometry; fitted identity, circuit, body sealing and removal clearance remain unresolved. The four old red meshes remain if the new source cannot load.
