2021 Toyota Supra Bulb Size

Goal: This bulb size chart helps you find correct replacement bulbs for a 2021 Toyota Supra, removing guesswork and reducing installation mistakes. Prerequisite: know the lamp location and current bulb code. I recommend using the chart to match housing type, wattage, and socket, then ordering the listed size. The trade-off is between OEM fit and upgraded brightness, so note that constraint before changing bulb type. Step by step: pick your lamp, confirm the code, and compare to the chart. Validation: test the new bulb for fit and function before final assembly. Troubleshooting: if a bulb won’t seat or flickers, recheck socket type and grounding.
