Ответ:Any small toggle switch can be used to switch from red to white LED. For a dimmer, you have a few options: A. Single channel 12V Dimmer: P/N # 11-16227 or P/N # 11-06674 B. Two channel 12V Dimmer- P/N # 11-10783: Using the 2-channel dimmer allows the customer to have one channel for White LEDs and another for Red LEDs, so no toggle switch is necessary for selecting the colors.
