This Module controls the automatic switching from DLR (Daytime Running Light) to low beam headlamp through a sensor. The switch time from DLR to low beam is less than 0.5 seconds; like when driving into a tunnel. Switch time duration from low beam to DLR is a slower 3 seconds; so light reflections of other traffic or street lamps will not influence low beam. Sensitivity can be adjusted and stored in 60 steps. - Dimensions: 38 mm x 16 mm x 11 mm - Body material: ABS with waterproof poured 2k epoxy resin - Sensor: 4.1mm LDR cell; front surface encapsulated against moisture - Connections: 0.14 qmm for input; 0.75 qmm for power outputs - Maximum output power: 2 x 60 Watt
