Due to the fact that highway tunnels are enclosed spaces with limited traffic space and difficult air circulation, the original traffic signs that relied on reflection quickly lose their reflective effect inside the tunnel due to air pollution. In order to better indicate traffic safety inside the tunnel, tunnel electric light signs were created in this context.
