Solution

1. Preparation

Gather tools and parts required.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Headlight Bulbs

Tools Required: Gloves, flathead screwdriver (if applicable).
Sub-steps:
1. Access the headlight assembly by opening the hood.
2. Remove the headlight assembly cover (if applicable) using a screwdriver.
3. Disconnect the bulb connector by pressing the release tab and pulling it out.
