To control, you need to choose the right button. There are two general types of buttons: self-locking and reset. Self-locking buttons are suitable for lights. Press to turn on, press again to turn off; reset buttons are used for speakers. Press to turn on, release to turn off.

There are many types of buttons. After comprehensively considering factors such as ease of installation, visual effect, and waterproofness, we finally chose a metal model with an indicator light.

This button has an LED indicator light that shows when it is turned on. It has multiple colors and is particularly effective at night. Here is the actual effect:

LED indicator lights have a variety of voltage specifications. Because they are powered by a single lithium battery, a 3-6V model was selected.

The switch and LED use two pins respectively, and the LED end has no positive or negative pins. In order to achieve the effect of pressing to light up, the wiring method is as follows:

Two self-locking switches are used to control the front and rear lights respectively, and a reset button controls the horn. For convenience, the buttons are directly installed on the solar panel. The actual effect after connection is shown in the figure:

• When drilling, be careful not to damage the metal sheet inside the solar panel, which will reduce the power of the solar panel.
