I'm impressed by the quality and performance of the TOSHIBA TAC8W Car Auxiliary Bulbs! These 31MM C8W 12V8W Festoon lamps emit a brilliant white light that completely transforms the ambiance of my car's interior. The brightness is just right, not too harsh on the eyes but still providing excellent illumination. Installation was a breeze, and the bulbs have been working flawlessly since I installed them. Highly recommend these bulbs for anyone in need of reliable and high-quality car lighting.
