BMW E39 Third brake light bulb replacement

BMW E39 Third brake light bulb replacement

Here are some common problems that can occur with the third brake light bulb in a BMW E39:

  • Burnt-out bulb

The most common problem with the third brake light bulb is that it burns out over time, causing the brake light to stop functioning. If this is the case, you will need to replace the bulb.

  • Loose connection

Sometimes the bulb may appear to be fine, but the connection between the bulb and the socket is loose, causing the brake light to flicker or not work at all. Try wiggling the bulb and checking the connections to see if this resolves the issue.

  • Faulty socket 

If the bulb and connections all appear to be fine, the issue may be with the socket itself. Over time, the contacts inside the socket can wear down or become corroded, causing a poor connection. In this case, you will need to replace the socket.

  • Electrical problem 

If the third brake light bulb keeps burning out, there may be an underlying electrical problem that is causing excessive voltage to be sent to the bulb. This could be due to a faulty wiring connection, a malfunctioning relay, or a damaged fuse. In this case, you will need to diagnose and repair the electrical issue before replacing the bulb.
