1991 Toyota Supra Bulb Size

Decision: This bulb size chart exists to help a 1991 Toyota Supra owner identify correct OEM and common aftermarket bulb sizes, reducing guesswork and fitment errors. As an observer_analyst I present the evidence clearly so you can verify part numbers and expected performance before purchase. Constraints and options are summarized in the list: factory halogen sizes, common LED and HID equivalents, and notes on sockets or adapters. A brief comparison highlights trade-offs in brightness, heat, and legal fitment, offering an interpretation of which replacements typically match factory compatibility versus those that may require modification. Recommendation and risks: use the chart to select bulbs that match socket type first, then compare light output and heat management.
