How much does it cost to replace a rear brake light?

Replacing a rear brake light bulb on your vehicle can be a relatively straightforward and affordable DIY task, but the total cost depends on several factors such as the type of vehicle, the bulb type, and whether you choose to do it yourself or have a professional handle the job. Here’s a detailed breakdown of the potential costs involved:

1. Cost of the Bulb

Standard Bulbs: The most common types of brake light bulbs are incandescent bulbs, which can cost anywhere from $5 to $20, depending on the make and model of your vehicle. LED bulbs, which are becoming more prevalent due to their energy efficiency and longevity, can range from $20 to $50 or more.

Specialty Bulbs: Some vehicles may use specialty bulbs that are more expensive due to their design or technology, such as high-intensity discharge (HID) or advanced LED systems. These can cost upwards of $100 per bulb.

2. Labor Costs

DIY: If you’re comfortable working on your car, replacing a brake light bulb is a task that typically requires minimal tools (like a screwdriver) and can be completed in under an hour. In this case, the labor cost is essentially zero, aside from your time.

Professional Service: Should you opt to have a mechanic or dealership replace the bulb, labor charges can vary significantly. The cost can range from $25 to $75 or more, depending on the shop’s hourly rate and the ease of accessing the bulb on your particular vehicle. Luxury cars or those with intricate designs may incur higher labor fees.

3. Additional Factors

Access Difficulty: Some vehicles have brake light bulbs that are more challenging to reach, requiring removal of interior panels or even trunk lining. This can increase labor time and costs if you’re not doing the work yourself.

Replacement of Entire Assembly: In rare cases, the entire taillight or brake light assembly may need to be replaced if the bulb socket is damaged or if the bulb is integrated into a sealed unit. The cost of a new assembly can range from $50 to several hundred dollars, plus labor.

Diagnostic Fees: If you’re unsure why your brake light isn’t working and take your vehicle to a mechanic, they might charge a diagnostic fee to identify the issue. This can range from $50 to $100 or more, depending on the shop.

Total Estimated Cost

DIY: For a standard bulb replacement, the total cost can be as low as the price of the bulb, which is typically under $20.

Professional Service: With labor costs included, the total could range from $50 to over $100, depending on the bulb type and labor rates.


Replacing a rear brake light bulb is generally an affordable repair, especially if you choose to do it yourself. However, costs can escalate with specialty bulbs, complex vehicle designs, or if additional parts need to be replaced. Before proceeding, it’s advisable to check your vehicle’s manual to confirm the correct bulb type and to assess whether it’s a task you feel comfortable tackling. If not, obtaining quotes from a few local mechanics can help you find the most cost-effective solution. Always prioritize safety and follow proper procedures when working with electrical components in your vehicle.
