  "limits": "Factory211lists North American side/flasherBHA5320fromGAN6-154101 with37H8759lens,GLB380bulb and27H6679grommet. Factory210indicator-onlyBHA5318/GLB382 and Holden UK-specL930 remain distinct; shared lens references do not prove identical complete assemblies. BP NorthwestBHA5320photo supplies morphology, while its1976-79label and Lucas56707/56705cross references are documentary comparisons, not fitted identification or a revision decision. Moss lists Lucas164-155and reproduction164-156separately. No direct owner lamp measurement or visible fitted mounting map was obtained from inspected photos. All new dimensions are rounded estimates: lens140x50mm,18mm depth, bowl144x54mm and36mmdepth,148x58mmflange,122mmfront screw spacing,1.5mmunloaded seal and all bulb/holder/grommet dimensions. The drawing centers are independent +/-0.46unit X,0.54unit Y andrigid_z(2.155)unit Z comparisons near the retained bumper, not photo-derived fitted locations. Both lamps share an unverified mirrored construction. Only the two front lens screw roles follow the product photograph; threads, engagement and hidden lamp-to-bumper fasteners are not established. No bumper/nose hole is cut and no neighboring geometry is moved to manufacture fit. Positive contacts/gaps are source-registration conflicts, not actual interference, sealing, tool clearance or a verified service path. GLB380is a listed role, without modeled filaments, wattage/voltage selection, polarity, ground, contact map or harness destinations. Three local tails are unassigned boundaries. Smooth lens surfaces do not reproduce flutes, optics, illumination or any regulatory approval. Grommet and lens seal are unloaded. No working circuit, fitted parts recommendation, safe removal order or verified replacement procedure follows."
