LED foglamp for volvo FH3/FM3

Kindly  note  that  the  original  vehicle  does  not  have  daytime  running  lights,  but  we  have  added  this function. There is a white positive wire for the daytime running lights left at the back cover of the headlights. If you need to use the daytime running lights function,  you  can  extend  the white wire  and  connect  it  to  the  nearest ACC  constant power  source to the headlights  then the daytime running lights can be used normally。
