The i.BOS - EL33 compensates for the lower electrical load drawn by LED bulbs compared to traditional incandescent bulbs. Without it, your motorcycle's warning light circuits may blink rapidly or fail completely when using LED conversions in dual-function rear light assemblies. It ensures proper indicator operation on classic BMW models.
The i.BOS - EL33 is specifically designed for BMW early models with dual-function rear lights. It is not suitable for all BMW generations. Always verify your specific model year before purchase. Modern BMW models with integrated electronic systems may not require this component.
Yes, for complete system functionality, you will need one i.BOS - EL33 unit parallel to your rear light and one i.LOAD - IL 7.5 parallel to your brake light. This dual-module configuration ensures all warning lights operate correctly across your entire rear lighting circuit.
The i.BOS - EL33 is mounted in parallel directly to your rear light assembly. Its compact size (92.7 x 15.9 x 16.1 mm) allows for discreet placement behind or beneath your tail section. Professional installation is recommended if you're unfamiliar with motorcycle electrical work.
LED indicator activation is possible on a case-by-case basis and requires software configuration. This depends on your specific BMW model and electrical setup. Kellermann recommends consulting with a specialist BMW technician to determine if your motorcycle qualifies for this enhancement.
