3157 4157 Load Resistor For Switchback LED Turn Signal Light Hyper Flash Fix US

What is 3157 4157 Load Resistor For Switchback LED Turn Signal Light Hyper Flash Fix US?

The 3157 4157 Load Resistor For Switchback LED Turn Signal Light Hyper Flash Fix US is a two-piece electrical solution designed to resolve common issues when replacing factory halogen turn signal bulbs with energy-efficient LED alternatives. Because LEDs draw significantly less current, many modern vehicles—especially European models with sensitive CAN-BUS systems—detect the change as a bulb failure, triggering rapid flashing (hyper flash) or dashboard error messages. This load resistor kit mimics the power draw of traditional bulbs, stabilizing the circuit and ensuring smooth, code-free operation of switchback LED turn signals.

Key features

• One Pair Included — Set of two 3157/4157 load resistors with wire adapters for dual-side installation.
• 50W 6-Ohm Rating — Built-in double load resistors handle high thermal output for reliable performance.
• Fixes Hyper Flash — Eliminates rapid blinking in turn signals caused by low LED current draw.
• Resolves Dashboard Errors — Prevents 'bulb out' warnings and flickering on CAN-BUS-equipped vehicles.
• Wide Compatibility — Works with 3157, 3357, 3457AK, 3357ALL, 4114K, 3157X, 3057KLCP, and 3757AK bulbs.
• 12V System Support — Designed for standard automotive voltage in passenger vehicles.
• Easy DIY Installation — No professional tools or mechanic required; connects directly to factory harness.

Who is 3157 4157 Load Resistor For Switchback LED Turn Signal Light Hyper Flash Fix US for?

This product is ideal for car owners upgrading to switchback LED turn signals who encounter hyper flashing or error codes. It's especially useful for drivers of European brands like BMW, Mercedes, Audi, and Volkswagen, which commonly use CAN-BUS monitoring systems. DIY auto enthusiasts looking for a plug-and-play fix without rewiring or coding will find this resistor kit a practical solution.

How does 3157 4157 Load Resistor For Switchback LED Turn Signal Light Hyper Flash Fix US compare?

Compared to basic flasher relays or single-resistor kits, this dual-pack offers balanced load correction for both left and right turn signals. Unlike plug-and-play decoders that may fail under sustained heat, these 50W resistors are built for durability. While not a permanent replacement for active CAN-BUS decoders in high-end systems, they provide a cost-effective, reliable fix for most standard LED bulb upgrades without requiring coding tools or professional installation.
