Options shown include common headlight, fog, brake, and interior bulbs, with interpretation of which sockets are most often encountered and a brief hypothesis about aftermarket fit differences. Comparison: the chart favors factory specifications over aftermarket labels to reduce ambiguity, and offers a recommended starting point for purchases. Recommendation: use the listed sizes as baseline, verify by inspection, and select bulbs rated for your driving conditions. Risks: trim differences or previous modifications may alter fit; check compatibility before installation.
