Replacing your car’s brake light is a straightforward task you can manage yourself. However, before jumping in, be sure to look at your car’s owner’s manual. It helps by giving you a diagram of where everything is, making the brake light replacement process even easier. 

Tools You Will Need to Replace Your Brake Light

  • Vehicle-specific brake light replacement bulb
  • Screwdriver
  • Ratchet
  • Safety goggles
  • Gloves
  • Bulb grease (if needed)

Steps to Replace Your Brake Light

1. Open Trunk

Safety first! Before opening the trunk, be sure to put on your safety goggles and gloves. Also, grab your car’s owner’s manual if you haven’t already. When handling any car parts, you want to ensure you’re not getting any substances on your hands or potentially damaging the bulb. It’s also a good practice to disconnect your car’s battery to prevent shock or electrocution, although it’s not mandatory. 

2. Pull out the Tail Light

If you need to pull out the actual light assembly, carefully unscrew any fasteners and bolts and slowly pull it out. Be careful of any wires attached to the bulbs. If you don’t need to remove the assembly, move on to the next step and pull out the bulb directly from the car. 

3. Pull out Bulb

Make sure you have gloves on when you remove the bulbs, as your skin’s salts and oils can decrease their effectiveness. Both substances can cause the heat in the bulb to concentrate and potentially burn out sooner or break. After putting on your gloves, turn the bulb socket toward the left, and it should easily come out. Then, pull the bulb out of the socket slowly.

4. Replace Bulb

You may want to use bulb grease to help you correctly install the brake light replacement bulb into the socket. Once you apply the bulb grease (if needed), slowly guide the new bulb into the socket. Then take the socket and carefully insert it into the same area it came from in the assembly or car. Slowly turn it to the right to secure it.

If you had to take out the assembly, grab those bolts and fasteners and reattach it to the car. Correctly line it up with its original spacing, so it fits and operates properly. 

5. Reconnect Battery

Lastly, make sure to reconnect your battery carefully. 

Important Brake Light Replacement Tips to Remember

  • Ensure the tail lights work – Before you put everything away, turn on your lights to ensure that the tail light you’ve replaced is working properly. If not, you may need to disconnect the battery and recheck the assembly or the car to confirm the bulb’s fit.

  • Select the right bulbs – All brake light replacement bulbs were not created equally. So, check the base of the old bulb for fitting details. Next, shop brake light replacement bulbs at AutoZone to find the correct bulb for your car. We offer a wide range of tail light bulbs, so start there to find the right one for your vehicle.  

  • Newer vehicles could take a bit longer – Tail light replacement on more recent cars may be a bit more complex, but not impossible! There could be more wires to disconnect, so make sure you have those tools handy.

  • Routinely check your tail lights – Once you finish with brake light replacement, plan to check your tail lights regularly. Because of their positioning, it’s hard to know if your tail lights are working properly. Therefore, set a date on your calendar every month to check to ensure your tail lights — and even headlights — are operational. Broken tail lights are not only a traffic violation, but they can contribute to a rear-end accident. So, make checking your tail lights a standard and routine inspection.
