Finish The Design That Datsun/Nissan Started! Improve your Z car's looks and aerodynamics. Our headlight covers are pre-drilled and made from impact resistant high strength plastic. This kit includes all mounting hardware, trim, and instructions. It requires no drilling of the headlight cases to install. Headlight covers should always be used in conjunction with H4 Headlights or MSR H4 Headlights to keep proper lighting strength. Note: Check local laws before ordering. Headlight covers may not be legal for road use in some areas.
