1. If you plan to install multiple lamps and synchronize them with each other, make sure that only one of them is connected as “MASTER”. NOTE: Only lamps of the same type and with the same number of lighting modes can be synchronized. 2. The Master, Slave function of the lamp is selected by connecting the white wire for the MASTER lamp or the yellow wire for the SLAVE lamp to the (-) power supply of the vehicle, respectively. 3. Changing the synchronization method to flashing in anti-phase is possible only for the SLAVE lamp(s), but without connecting to the MASTER circuit. During operation of the SLAVE lamp(s), the white wire must be short-circuited to the (-) of the power supply for about 5 seconds. The change will be confirmed by skipping one series of flashes. Re-short-circuiting the white wire to the (-) of the power supply in SLAVE mode will set the lamp to synchronize in phase. All SLAVE lamps for which the operating phase needs to be changed can be switched together. 4. To change the pattern, short the synchronization line for approximately 1 second to the ( ) of the power supply. The MASTER lamp imposes the pattern number on the SLAVE lamps.
