About Wehrle Electronics

Founded in 1952 by Johann Wehrle, Wehrle Electronics has spent more than seven decades earning a reputation as one of the most dependable names in automotive electronic components. What began as a focused effort in producing voltage regulators has grown into a comprehensive lineup of relays, timers, flashers, and control devices trusted by technicians and enthusiasts across the globe. The brand's longevity is no accident — it reflects a consistent commitment to precision engineering and component reliability in demanding automotive environments.

A Specialization Built on Relays

At the heart of the Wehrle catalog is an extensive range of relay products. Multi-purpose relays are among the brand's most versatile offerings, designed to handle a wide variety of switching applications across different vehicle makes and models. Whether you're replacing a failed relay in a European import or sourcing a spare for a fleet vehicle, Wehrle's 12V and micro relay formats are engineered for drop-in compatibility and long service life.

For engine starting systems, Wehrle's ignition relays deliver the switching reliability that modern ignition circuits demand. These components are built to withstand the thermal and electrical stresses of repeated engine start cycles, making them a solid choice for high-mileage vehicles where OEM parts may be showing their age.

Diesel vehicle owners will find particular value in the brand's diesel glow plug relays. Cold-start performance in diesel engines depends heavily on the glow plug system functioning correctly, and a quality relay is the linchpin of that system. Wehrle's glow plug relay offerings reflect the brand's deep understanding of diesel-specific electrical requirements.

The fuel pump relay lineup rounds out Wehrle's coverage of critical engine management circuits. Fuel pump relays are among the most frequently replaced electrical components in aging vehicles, and Wehrle's range — spanning six product variants — ensures broad fitment across numerous platforms.

Lighting Control and Safety Systems

Beyond engine electronics, Wehrle produces hazard warning and turn signal flashers, including LED-compatible units that meet the needs of modern vehicles equipped with energy-efficient lighting. As LED lighting upgrades have become more common, the demand for correctly rated flasher units has grown — and Wehrle's flasher lineup addresses both conventional and LED applications with purpose-built components.
