Both the Sylvania and PIAA halogen bulbs will not give you the pure white colour of a good LED bulb. Trust me, I have tried them both already. Apparently its the voltage of the DRL (or something like that) that is too low when running the DRL's. When you run High Beams, the colour is good, but not when running DRL's.
If you want the pure white DRL, you have to go LED and resistors, but you will lose your high beams. If you need High Beams, stick with Halogens.
I have the XP80 LED from Diode Dynamics with resistors. The High Beam does function but the reach is just not there, unlike Halogen bulbs. Its a trade off.
