Very small electronic flasher unit consisting of 2 small electric components only during operation with an incandescent lamp. Circuit diagrams for many variations are enclosed. It is also possible to connect LEDs. However, these must be then operated with additional protective resistors (not included). 3 additional resistors (not included), which are tailored to the respective configuration are required for the operation as alternating flasher. The components have to be connected by using a soldering iron.
