- Why some buyers install the rocker switch but the light on the switch stays on all the time?

- If you wire the harness to the car battery directly, the rocker switch will glowing all the time. When you turn on the light then the switch stays on both up and down led light, when you turn off the light the upper led will not stay on but the down led is still on.

  If you don’t want the switch always stay on, you can hook the harness to a source on your fuse panel.
