In this tech article, I will show you how to replace the taillights on your BMW E61 wagon.

E60 / E61 exterior bulbs are monitored by the Light Module (LM), which also monitors adaptive headlight function (where equipped) and controls instrument panel dimming. LM is also capable of switching lighting functions in case of a fault. For example, in case of a taillight bulb failure, brake light bulbs are used as a substitute.

Bulb monitoring by LM is done both cold and hot (unlit or lit). In cold monitoring, LM sends brief current pulses to unlit bulbs to measure their resistance. The pulses are too short to illuminate bulbs but serve the purpose of evaluating whether an individual bulb or bulb circuit is defective. In hot monitoring, LM measures the current to individual lit bulbs to determine overload or a break in the circuit.

When dealing with bulb failures or bulb out messages, always inspect the electrical connector and taillight bulb holder. The connectors can wear over time causing heat and melting. Once the electrical connector on the harness side or the taillight socket has melted, you will have a poor connection and rear bulb faults or failures. If you find the connector is melted, you can repair it by installing a new plug pigtail and / or replacing the bulb socket assembly. See our tech article on taillight wiring replacing.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.
