2002 Mazda RX-7 Bulb Size

Decision: the list identifies compatible bulb sizes and types for a 2002 Mazda RX-7 to simplify selection and reduce installation errors. Constraints include model-year variations and limited manufacturer notes, so the interpretation relies on cross-referenced parts data and practical evidence from installations. Options are presented by bulb location and type so you can compare halogen, HID-style, and LED alternatives along brightness, heat, and fit. My hypothesis, based on hands-on reference and parts tables, favors matching base size first and then considering trade-offs in efficiency and beam pattern. This comparison highlights limitations in aftermarket claims and guides a pragmatic choice. Recommendation and risks are explicit: follow the listed sizes for fitment and check local regulations for light output changes; improper choices can affect visibility or legality.
