Signs of a Failing Brake Light Switch
The brake light switch on the E24 M6 is a mechanical part that wears out over time. Failure is gradual, but the symptoms are usually clear. Recognizing them early is key to maintaining safety.
Key Symptoms of Failure
- Brake Lights Don't Work: The most serious symptom is when your brake lights fail to illuminate when you press the pedal. This is a major safety hazard.
- Brake Lights Stay On: The switch can also fail in the 'on' position, causing your brake lights to remain lit even when your foot is off the pedal. This can drain your battery and confuse other drivers.
- Cruise Control Issues: If the switch is faulty, it may prevent you from setting the cruise control or cause it to disengage unexpectedly.
Choosing the Right Aftermarket Switch
For a classic like the E24 M6, the difference between OEM and aftermarket can be a major consideration. The original BMW switch is a high-quality part, but several reputable aftermarket brands offer reliable alternatives at a lower cost. Your inventory price range is from $18.96 to $26.10.
Here is a general breakdown of the available brands:
- Standard Ignition: Generally considered a reliable mid-tier to upper-tier aftermarket brand. They are known for producing parts that meet or exceed original specifications and are a solid choice for a daily driver or a car you depend on.
- Facet: A European brand that manufactures a wide range of electronic components. They are often seen as a good quality, reliable alternative to OEM parts.
- URO Parts: URO is known for providing budget-friendly parts for European vehicles. While they make many parts more accessible, their quality can sometimes be inconsistent. For a critical safety component like a brake light switch, consider it a budget-tier option.
Pro Tip: Given the low cost of even premium aftermarket options and the switch's critical safety function, opting for a brand like Standard Ignition or Facet is a wise investment in reliability and peace of mind.
