US-spec plastic headlights are universally considered inferior (poor output, fogging, scratching); upgrade paths include glass Euro ZKW/Bosch units (often refurbished or RHD/LHD-convertible projectors), aftermarket Depo glass copies (decent but lower quality), and HID retrofits; Euro lights are increasingly considered an essential upgrade.
Headlight options: US plastic, Euro ZKW/Bosch, and aftermarket Depo
