微处理器13与汽车内部的汽车运行处理元件电性连接，且汽车运行处理元件包括刹车油压检测传感器、ABS泵、车速传感器、车载导航系统、光线传感器和雾灯开关，如图4-7中，通过将微处理器13与汽车中的运行处理元件电性连接，可以对刹车力度，车速以及 环境光线进行感应，方便微处理器13进行后续的处理和控制；
微处理器13与汽车中经济模式和运动模式的控制开关电性连接，且微处理器13通过感应经济模式和运动模式的控制开关控制车速显示灯带221和刹车力度显示灯带222的亮度，如图8中，在经济模式和运动模式下，可以通过微处理器13控制车速显示灯带221和刹车力度显示灯带222的亮度，以便后车观察；
微处理器13与汽车中的车载导航系统电性连接，且微处理器13通过感应车载全球定位系统的所处位置信号及道路限速信息控制刹车力度显示灯带222的亮度及车速显示灯带221的长度和亮度，微处理器13与汽车中的光线传感器和雾灯控制开关电性连接，且微处理器通过感应光线传感器和雾灯控制开关控制开关控制车速显示灯带221和刹车力度显示灯带222的亮度，如图1、图7和图9中，在不同的道路上，车速显示灯带221和刹车力度显示灯带222会显示不同亮度，同时车速显示灯带221显示最大长度和亮度与该道路的最高限速相匹配，即刹车及车速显示灯带221的亮度与当前道路限速的时速成正比，当前车踩刹车时，可尽量避免前车刹车及车速显示灯带221亮度对后车的视线干扰。(当车辆无车载导航系统时，车速显示灯带221默认当前限速为时速70公里)，在不同的道路环境光线下，车速显示灯带221和刹车力度显示灯带222均有不同的亮度；当雾灯开关打开时，车速显示灯带221和刹车力度显示灯带222亮度达到最大。
安装筒21的内壁上等角度固定有齿块211，且齿块211与齿辊 32之间相啮合，并且齿辊32上的锯齿范围占整体的一半，安装筒21端部的外侧固定有导杆23，且导杆23位于导槽24内，并且导槽24开设于活动槽2的内壁上，同时导杆23与导槽24之间固定有弹簧25，导杆23通过弹簧25与导槽24之间构成周向弹性滑动结构，且导槽24呈弧形结构与安装筒21之间共中心轴线，如图1-3中，微处理器13感应到刹车时，控制微型电机3的运行，通过同步带31驱动齿辊32的转动，齿辊32与齿块211啮合，带动安装筒21在活动槽2内转动，安装筒21上的导杆23在导槽24内转动，同时当齿辊32不与齿块211啮合时，在弹簧25的作用下，导杆23带动安装筒21往回转动，实现安装筒21的往复转动，可以通过安装筒21带动安装板22上的车速显示灯带221和刹车力度显示灯带222往复转动，提高警示效果；
车速显示灯带221和刹车力度显示灯带222依托于安装板22在安装筒21上等间距排列，且安装筒21上排列的车速显示灯带221和刹车力度显示灯带222的长度依次递减和递增，如图1和图4-6中，微处理器13通过刹车油压检测传感器、ABS泵感应刹车力度的变化，微处理器13控制刹车力度显示灯带222的亮起，并根据刹车力度的大小，刹车力度显示灯带222的亮起的数量和面积增加，方便给后车一个直观的观察，同样的，微处理器13通过车速传感器感应车速并控制车速显示灯带221亮起，通过控制车速显示灯带221亮起的数量和面积，对车速进行展示；
车速显示灯带221和刹车力度显示灯带222的亮度根据长度分别 依次递减和递增，且车速显示灯带221和刹车力度显示灯带222整体的亮度分为多个阶层，刹车力度显示灯带222显示颜色为红色，车速显示灯带221显示颜色为绿色；并且刹车力度显示灯带222的颜色根据排列分别依次由浅到深和车速显示灯带221的颜色根据排列分别依次由深到浅，如图4和图7-8中，通过设置递增的亮度和颜色，提高警示效果，同时方便在不同环境下两种亮度的切换。
工作原理：在使用该车辆刹车力度感应变化显示的刹车灯时，首先微处理器13感应刹车力度，通过微处理器13感应车辆刹车力度，控制刹车力度显示灯带222整体的显示面积、亮度和颜色，对刹车力度进行对应直观的感受，同时通过微处理器13感应车辆车速，控制车速显示灯带221整体的显示面积、亮度和颜色，对车速进行对应直观的警示；
接着，在进行灯控操作时，微处理器13控制微型电机3的运行，通过同步带31驱动齿辊32的转动，使其与齿块211啮合，带动安装筒21转动，同时，导杆23通过弹簧25在导槽24内弹性转动，配合半齿结构的齿辊32，使得安装筒21带动车速显示灯带221和刹车力度显示灯带222往复转动，提高警示效果。
