DRL strip is OEM with no mod. As you can see the light projected by the LED bulbs (low beam and fog light) were pure white (not bluish/ricey) . The low beam is my "newer led bulb (about one year old)" where the fog is the "older led bulb (about three years old now)" Had to do the change bc of a frontal impact accident about a year ago and the original led bulbs I had ordered some three years ago (the one in the fog) are no longer available. So I bought newer led bulbs (sold in pairs).
