2017 Audi R8 Bulb Size

Decision — Provide a concise bulb size chart for a 2017 Audi R8 that lets a technician or owner identify correct replacements quickly, with enough context to avoid common mistakes. Constraints — Variations in trim, aftermarket lighting, and regional specifications mean a single list is a hypothesis rather than an absolute rule, so verification against the vehicle manual and the lamp socket is recommended. Options — The list compares common socket types used for headlights, tail/brake, turn signals and interior lamps, noting where LED modules replace traditional halogen sizes. Comparison — For each circuit I contrast typical OEM fittings with common aftermarket equivalents to highlight likely compatibility and limitations. Recommendation — Use the chart as a reference, confirm by inspection, and prefer OEM or equivalent spec bulbs when in doubt. Risks — Incorrect fit, electrical mismatch, or warranty implications; affiliate links on this page may earn a commission if you purchase through them, and this does not affect the integrity of the comparisons.
