The people with visual impairment have problems in mobility and orientation, especially in the outdoor environment. Recently, traffic lights systems, which is a facility where someone crosses do not support visually implaired people so they still need help from others in crossing the road. In this study, a system that integrates traffic lights is implemented using Visible Light Communication (VLC) technology, where the VLC transmitter is mounted on a traffic light, and the VLC receiver is installed as a wearable device that can be used with the audio information signal. The measurement is done by considering the use of color filters. The measurement results show that the transmitter system has been able to send signals with audio frequencies from 300 Hz to 4000 Hz. Besides that, receiving an information signal consisting of a audio signal from a transmitter mounted on a traffic light with a red, yellow and green color filter can be received by a VLC receiver that is placed on a visually impaired person of good quality with the signal voltage received above 4 Vpp, where the use of a yellow filter shows the best signal reception results with a voltage output of 5.00 Vpp at a frequency of 2400 Hz compared to other color filters.
