This guide will walk you through the process of replacing your Nissan Sentra headlight, step-by-step.

Gathering Your Tools and Parts

Before you begin, you’ll need to gather the following tools and parts:

• New headlight assembly: Ensure you purchase the correct headlight assembly for your year and model of Nissan Sentra. You can find these at your local auto parts store or online retailers.

Safety First: Precautions Before You Start

Before you begin working on your car, it’s crucial to prioritize your safety:

• Park your car on a level surface and engage the parking brake. This prevents the car from rolling while you’re working.
• Turn off the ignition and disconnect the negative battery terminal. This will prevent any electrical shock.
• Wear safety glasses to protect your eyes from debris.
• Make sure the area around your car is well-lit.
