晚上开着的树莓派老亮着那盏红色电源指示灯，感觉非常不舒服，狠想关掉它！我还是比较喜欢把麒麟座上的RGB灯调成蓝色做小夜灯，毕竟往上照射的灯光不会让人感觉不舒服。
将以下几行加到 /boot/config.txt 即可禁用树莓派 Model 2B 的两盏指示灯。(The raspberry pie that was on at night was always lighting the red power indicator. It was so uncomfortable that it was hard to turn it off! I still prefer to turn the RGB light on the constellation of the unicorn into blue for the night light, after all, the upward illumination is not uncomfortable.
Add the following lines to /boot/config.txt to disable two indicator lights of raspberry Model 2B.)
