A load equalizer (or flasher relay adapter) compensates for the different electrical load of LED turn signals compared to traditional incandescent bulbs. When upgrading to LEDs or higher-wattage bulbs on classic motorcycles, the turn signal circuit may not recognize the new bulbs, causing rapid flashing or warning lights. The i.SED-V12 solves this by balancing the electrical load.
Yes, if your BMW is equipped with a 12-volt electrical system. This adapter is specifically designed for classic motorcycles with non-standard grounding configurations, which is common in BMW K-series and older models. Check your motorcycle's original wiring diagram to confirm 12V operation before installation.
The i.SED-V12 is primarily designed for LED turn signals and higher-wattage applications. While it can work with standard incandescent bulbs, its main purpose is to handle the lower power draw of LEDs and ensure proper circuit function. For best results, pair it with quality LED indicators.
In traditional automotive wiring, the positive wire is switched on/off. Some older motorcycles (especially classics) use 'switched ground' systems where the ground circuit is interrupted instead. The i.SED-V12 is specifically engineered to work with these non-standard configurations, making it essential for certain vintage builds.
At just 40.7 x 21.6 x 6.8 mm and 32 grams, the i.SED-V12 is extremely compact. It fits easily in tight spaces common in custom motorcycle builds and classic restorations, allowing discreet installation without compromising your bike's aesthetics.
If you're experienced with basic motorcycle electrical work, installation is straightforward. The adapter is compact and integrates into your existing wiring harness. However, if you're unsure about your motorcycle's electrical system, we recommend consulting a qualified mechanic familiar with custom builds to ensure proper installation and safety.
No, that's the primary purpose of the i.SED-V12. It prevents false warnings and erratic flashing by properly balancing the electrical load. Once installed correctly, your turn signals will function normally without triggering dashboard warnings, even with upgraded LED indicators.
Kellermann is a reputable European manufacturer known for producing parts that comply with ECE and E-mark standards. However, for specific legal compliance in your region, verify that your complete turn signal setup (including bulbs and housing) meets local regulations. Consult local traffic laws or your local motorcycle authority.
