and high quality,Mini shape,light weight and waterproofFit for of , Time-lapse power off functionConstant light + dimming + delay + automatic switchSimple installation,with no need to change any electric lineIntelligent start up: When the car is started (the voltage must be higher than 13V+), the daytime running light is automatically turned on. When the headlights (or reading lights) are turned on, the daytime running lights are dimmed (darkened), when the car is turned off (the voltage must be lower than 12.5V) , the daytime running light is off after 15 seconds!Name:Daytime Running Lights ControllerItem Type: Day LightInterface Type: NoneFor Vehicle /Model: UniversalItem : DRL ControllerWattage: DRL ControllerVoltage: 12-18VWorking current: 3ATime-Lapse Power Off: 15sNote:After the battery is connected, the daytime running light will turn on for about 15 seconds and then turn off the light. This is a normal phenomenon (realizing the delay function). After that, you need to start the car. When the voltage reaches 13V+, it will start working!The Scope of Products:1. The starting voltage is 13V+, and the flameout voltage is lower than 12.5V (if it is higher than this value, it will be extended for a few minutes until the voltage .)2. 1 pair of daytime running lights power does not 18W (most of the daily running lights will not the power)Wiring Instruction:1.
