Just like mine, only in Silver.
And again:
Depo Headlights (with 4 LED Bulbs per ring):
Sonar Headlights:
"Do you mean that the red and black wires for the LEDs need to be spliced with the yellow and black wires as shown in the red box in this pic?"
No. They need to "spliced" with the white and black wires of YOUR car (with the parking light wires, so you get the ring shining as soon as the parking lights, or "stand lights" are on).
