This compact resistor harness plugs inline with your 3157\/4157\/T25-style LED turn signal bulbs and increases the circuit draw to mimic the original bulb load. Designed for do-it-yourself installation, the harness is a simple electrical solution for common LED conversion issues without modifying the vehicle’s wiring harness permanently.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the harness stop hyper flashing and bulb-out warnings?\u003c\/h3\u003e\n\u003cp\u003eThe harness places a 50W, 6-ohm resistor in parallel with the LED lamp, increasing total circuit wattage so the vehicle sees a normal load. That prevents the flasher or BCM from interpreting the LED as a failed bulb and returns flash cadence to normal.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWorks by adding resistive load equivalent to original incandescent bulbs\u003c\/li\u003e\n  \u003cli\u003eResistor rated 50W, 6 ohms, suitable for most 12V systems\u003c\/li\u003e\n  \u003cli\u003eParallel connection avoids altering LED wiring polarity\u003c\/li\u003e\n  \u003cli\u003eInstalls inline—no cutting of factory harness required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich bulb sockets and vehicles is this compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis harness is made for 3157, 4157 and T25-style sockets and a range of related part numbers listed in product specs.

It suits those using 3157\/4157\/T25-style LEDs and who can mount a heat-producing resistor safely. If your vehicle uses a CK socket or specific excluded models, check fitment before buying. The gopupu harness is a practical, inexpensive accessory to restore correct signal behavior without modifying factory electronics.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this harness work with my 3157 LED bulbs?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—if your bulb uses a 3157\/4157\/T25-style three-locking-tab connector, this harness will add load to stop hyper flashing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the resistor be installed near plastic housings?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No—the resistor gets very hot.
