Aspects of the present invention relate to methods (60) of traffic light signal detection. In particular, an aspect of the invention relates to a computer-implemented method (60) of determining a status of a traffic light (111) in an image of the traffic light (111). The method (60) comprises: receiving an image of the traffic light (111); dividing the image of the traffic light (111) into at least two portions, including a proceed-signal portion (132) and a stop-signal portion (134); determining a first brightness value of a HSV colour representation of one of the proceed-signal portion (132) and the stop-signal portion (134); comparing the first brightness value to a first threshold; and identifying a first status of the traffic light (111) if the first brightness value is greater than or equal to the first threshold.
