The Phillips Daytime4 is an extremely bright
LED DRL kit that is equal to the OEM DRL's on newer Mercedes and Audi's. The instructions are very clear and accurate and the install is easy. The kit comes with everything for those who want to add this type of DRL.
1) Mount the light , brackets only first, where you want them, screw mount or double-sided tape. (I had the chrome grill off, as I was painting it black to match) I chose to mount them vertically in the ovals of the grill. I use a level to "level" them vertically and horizontally. They are flush with the grill. The kit contains enough wire so you can place them anywhere up front.
2) Attach the positive + lead and negative - lead of the main harness to the posts where you would jump the vehicle.
3) Attach the control module to a secure location. I chose the convenient slot on the passenger end of the black metal bracket, on the fuse block. Attach the only power module wire to the back of the front amber turn signal bulbs. On our vehicle the center wire is the proper one. A small blue led light on the module lights to confirm connection to the proper lead of the back of the turn signal. The kit comes with an in-line connector. It signals the module that the lights are on and the DRL's go off.
4) DRL's come on when you start the vehicle and go off when you turn on the parking lights or headlights.
