Reverse light bulbs in any car will eventually need replacement, and the light bulbs in the BMW F30 are no exception. After years of use, the factory halogen bulb will stop emitting light and iDrive will promptly notify you that a reverse bulb is out.
You might be surprised by the number of different bulb types that you have to choose from – it’s not as simple as picking up bulbs for your home. The F30 reverse light bulb can be replaced with a traditional halogen bulb or with a compatible LED replacement.
Read ahead to find out all about some of the best BMW reverse light bulbs on the market today.

They are 4 times brighter than standard halogens but use just a fraction of the power. They are also designed to be as compatible as possible if you are looking to make the switch over to LED bulbs.
They are also likely to last much longer than any halogen bulb as they have more stable performance and better heat dissipation, so they don’t wear down over time.

How to Replace BMW F30 Reverse Lights
Replacing the reverse lights on an F30 is a simple procedure; similar to doing it on an older 3 Series. Here is the step-by-step process:
- Open the trunk and remove the trunk lid trim so that you can access the taillight assembly.
- Unclip the bulb assembly from its position.
- Push the old bulb inwards, rotate it to the left, then remove it.
- Push the new bulb into place and rotate it to the right so that it locks in place.
- Re-clip the light assembly into its position.
- Repeat for the other bulb.
If replacing the bulb with a traditional halogen bulb or a CAN-bus compatible LED bulb, there are no further steps needed.
If replacing it with LED bulbs not compatible with CAN-bus, you may need to code them to make sure they are properly recognized and the iDrive error goes away. Here is a video is the full installation process:
Additional Considerations When Replacing F30 Reverse Lights
LED vs. Standard Bulb
LEDs are brighter and output a cooler temperature light, often providing more than 400% of the luminosity that a standard bulb gives out. They have a much longer lifespan, which means fewer replacements over time, and they also turn on instantly at full power.
If you plan to keep your car for a while, upgrading halogen bulbs to LEDs changes how your car looks at night due to the cooler and brighter light output. You can retrofit LEDs into virtually every bulb socket.
On the other hand, standard halogen bulbs are much cheaper to purchase, and you may want to opt for them if your vehicle has halogen bulbs installed already to avoid any compatibility troubleshooting or the hassle of coding.
What is the difference between P21W/H21W and 1156 bulbs?
P21W and H21W refer to traditional incandescent bulbs while 1156 refers to LED bulbs. Both of these use the same socket; you can use 1156 LED bulbs to replace either P21W or H21W halogen bulbs.
Would an LED replacement bulb bring up any error codes?
If your LED bulbs are not compatible with the F30’s CAN-bus, then you are likely to see error codes and they may not function properly. High-end LED bulbs such as Sylvania ZEVO have a built-in chip for the ECU to recognize it as a regular bulb.
It is recommended that you code your F30 so that it recognizes you are using LEDs instead of standard halogen bulbs.
If you want to replace the reverse light bulbs in your F30, things are a lot simpler than you might think – although there are a few things you need to be aware of. Make sure you are selecting P21W/H21W or 1156 bulbs, and you will need to choose between standard halogen bulbs and LED bulbs.
Halogen bulbs are simple to replace and easy to find at any hardware or automotive store, but they are not likely to last as long as LEDs. Additionally, LED bulbs are brighter and achieve full power instantaneously, although they may require coding.
