Wehrle Turn Signal & Hazard Warning Flasher Relays
When a turn signal flickers erratically or a hazard warning system stops responding, the culprit is almost always the flasher relay — a small but safety-critical component buried in the vehicle's electrical system. Wehrle has been a trusted name in automotive electronics for decades, and their hazard warning and turn signal flasher relays represent some of the most reliable OEM-grade replacements available for European vehicles.
A European Electrical Specialist
Wehrle Autoelektronik is a Germany-based automotive electrical supplier with deep roots in the Baden-Württemberg region. With over six decades of experience, the brand has built a reputation for developing electronic components and complete systems to the exacting standards demanded by European automakers. That heritage translates directly into their flasher relay lineup, which is engineered to match factory specifications across a wide range of vehicle platforms.
OEM-Grade Fitment for Porsche, BMW, Volvo & More
What sets Wehrle apart in the flasher relay category is their focus on precise, vehicle-specific fitment. Their flasher relay catalog covers an impressive range of classic and modern European vehicles, making them a go-to source for enthusiasts and professional technicians alike. Key applications include:
- Porsche — Wehrle relays such as the WES 54 201 102A (part no. 914-618-303-12) are OEM-referenced replacements for the Porsche 911, 912, 914, and 930, covering model years spanning the 1960s through the 1980s and beyond.
- BMW — The Wehrle 54-201-101 (BMW OE cross-reference 61-31-1-371-909) is a direct-fit 3-prong hazard/turn signal flasher relay for a broad range of BMW models including the 318i, 325i, 325e, 535i, M3, M5, and 635CSi.
- Volvo — Their 4-pin 12V flasher relay (part no. 54-201-102) also carries OEM cross-reference numbers for Volvo, confirming its roots as a factory-supplied component.
How Wehrle Flasher Relays Work
A flasher relay regulates the flashing cycle of your vehicle's turn signals and hazard lights — controlling both the rate of flash and the consistency of the signal. Wehrle's relays are designed to maintain a steady, visible cycle that meets road safety standards. Their compact form factor ensures easy installation into existing vehicle circuits, while the use of quality internal components supports long-lasting electrical performance. The result is a drop-in replacement that restores correct function without modification.
Why Choose Wehrle for Your Flasher Relay?
For owners of classic and vintage European vehicles in particular, sourcing a flasher relay that truly matches the original equipment standard is non-trivial. Wehrle's part numbers cross-reference directly to OEM numbers from Porsche, BMW, and Volvo, giving buyers confidence that the relay will integrate correctly with the vehicle's wiring harness and flash at the proper cadence. Whether you're restoring a classic Porsche 911 or performing routine maintenance on a BMW E30-era model, Wehrle offers the kind of exacting fitment that aftermarket generics simply can't guarantee.
