I just installed the Osram Night Breaker Plus to replace my DRL.

The bulbs looks WHITE/bluish inside the box, but after I put them on ... my DRL still seems yellowish? not too much of a different than the OEM H11 which where yellow and dull looking.

I also changed out the same peanut 168 bulb to V-Led 12 led and those looks "WHITE".

So, now I have to turn on my parking light to blend in with the Osram Night Breaker DRL to give it that "White" look while driving.

 

DRL doesn't run at full power (I believe 40% or 50%) so you'll never get that "white" or "blue" look. The only way is to install a DRL LED kit but the downside is you'll lose your high beams.

 

that's because all those halogen bulb require full wattage in order to give it the full white/bluish color, and the DRL from car will only output on half of the wattage, so the bulb will look like oem yellowish. but if u turn on ur high beam, the bulb will run in full wattage and it'll give u the white/bluish looks. so if u want the white/bluish looking DRL, u have to go w/ LED bulb w/ decoder.

 

No halogen bulbs will have a white output when they are running as DRL's. The color of the bulb is rated when running at full power. Only partial power is going to the bulbs when used as DRL's so it'll be yellow no matter what bulb you use.

There's two options to get rid of the yellow look. I have the dealer disable my DRL's. The other is to buy the LED DRL kit which will be white but aren't functional as high beams. Disabling the DRL's is probably the best choice in my opinion. You still get to use your white high beams and no yellow look plus it saves power since you don't have DRL's.
