Owning a Tesla Model 3 is a thrilling experience, but like any vehicle, it requires maintenance over time. One common maintenance task you might encounter is replacing a headlight.
Whether it’s due to a burnt-out bulb or a damaged headlight assembly, knowing how to replace the headlight on your Tesla Model 3 can save you time and money.
In this guide, we’ll walk you through the cost and process of replacing a Tesla Model 3 headlight.
Cost of Replacing a Tesla Model 3 Headlight
Before delving into the process, it’s essential to understand the potential cost involved in replacing a Tesla Model 3 headlight. The cost can vary depending on several factors:
Warranty Coverage: If your Tesla Model 3 is still under warranty, the headlight replacement may be covered, reducing or eliminating the cost. Check your warranty documentation for details.
DIY vs. Professional Installation: The cost will differ significantly depending on whether you choose to replace the headlight yourself or hire a professional mechanic. DIY can save on labor costs, but you’ll need to purchase the necessary parts.
Type of Headlight Assembly: The cost may vary depending on whether you need to replace just the headlight bulb or the entire headlight assembly. A new bulb is generally a lot cheaper than a complete assembly.
OEM vs. Aftermarket Parts: Opting for original equipment manufacturer (OEM) parts can be pricier than choosing aftermarket alternatives. OEM parts are made by the manufacturer and are designed to meet the highest quality standards.
Labor Costs: If you decide to have a professional mechanic replace the headlight, labor costs can vary depending on the shop’s hourly rate and your location.
On average, the cost of replacing a Tesla Model 3 headlight bulb can range from $50 to $150, while replacing the entire headlight assembly can cost between $500 and $1,500, including parts and labor.
