BMW Isetta electrical system

€29.90

incl. 19% VAT plus shipping

The 7-900 turn signal relay for the BMW Isetta is an original 12V new part that, depending on the version, can control various lamp loads (e.g., 2x15 W or (2+1)x21 W) and thus defines the flashing frequency of the turn signals. During restoration, it is recommended to replace old thermal relays with worn contacts with a new part like this one, specifying the actual lamp wattages installed to ensure correct matching. This restores the BMW Isetta’s turn signal system to reliable operation and meets the technical requirements for historic driving.
