相反的横梁点亮象横向的对称的点亮并且纵的对称的点亮一样被介绍。模拟实验被使用为上述三点亮软件点亮方法的 DIAlux 执行。结果证明因为它残疾瞪视的阀值增长更大，灯光的那根相反的横梁是更合理的在隧道入口地区被收养。相反的横梁点亮能与横向的对称的点亮并且纵的对称的点亮相比改进障碍和灯光的效率的背景发光性。因此，点亮节省精力的罐头的隧道被减少道路发光性要求和星力量完成。纵的对称的点亮对在隧道的大星间距导致内部地区；电源消费能被减少因此减少星的数字使用了。掘墙是不合适的与光滑或明亮的材料铺。星的安装高度在相反的横梁点亮上有更少的效果。
Counter beam lighting was introduced as well as transverse symmetrical lighting and longitudinal symmetrical lighting. Simulation experiments were carried out by using DIAlux lighting software for the above three lighting methods. The results show that counter beam lighting is more reasonable to be adopted in the tunnel entrance zone because its threshold increment of disability glare is greater. Counter beam lighting can improve the background luminance of the obstacles and lighting efficiency compared with transverse symmetrical lighting and longitudinal symmetrical lighting. Therefore, tunnel lighting energy-saving can be achieved by reducing the road luminance demands and luminaries power. Longitudinal symmetrical lighting is conducive to the large luminaries spacing in the tunnel internal zone; so power consumption can be reduced by decreasing the number of luminaries used. Tunnel walls are unsuitable to pave with smooth or bright material. Installation height of the luminaries has less effect on counter beam lighting.
