The hugely versatile ST4 Evolution has long been a favourite of many Triple-R customers. Measuring 204mm in length, the ST4 produces 4,136 lumen, with the 1 lux line reaching 278m. Seen here as a pair of lights, compared to the standard vehicle lights (Audi LED - high/low beams), the ST4's deliver a 'wall' of light both in regards excellent spread of light even to the sides of the road close the vehicle, alongside good mid to long-range illumination. At 5000K, the colour of light is carefully selected to maximise definition and sharpness of objects ahead, while being comfortable on the eye.

Lamps in the video are mounted at licence plate height (550mm from the road), because of the higher vertical angle of light (+/- 12 degrees), we would advise against mounting any ST Evolution lamps much lower on the vehicle.
