2019 Audi RS 5 Bulb Size

If you’re replacing lights on a 2019 Audi RS5, the main problem is matching the exact bulb size and spec to avoid fit or performance issues. This bulb size list exists to remove guesswork by showing recommended OEM sizes, common aftermarket equivalents, and any trade-off between brightness and heat. Treat it as a reference for parts selection under typical constraints. Before ordering, validate fit against your vehicle’s manual and inspect the housing type. The chart assumes standard factory options; if your RS5 has aftermarket or upgraded lighting, double-check the socket and CAN-bus compatibility. Use the list to speed parts sourcing and as a practical checklist during installation. Some product links are affiliate links, which means we may earn a commission at no extra cost to you. That helps fund accuracy checks and updates. If a listed size doesn’t fit, re-validate the socket and report the discrepancy so we can update the chart.
