The DRL's are a 4114. Same as the 3157, they just don't run as hot....there is a easier and cheaper way to get the same look. White LED's are close and they have them as replacement bulb. The other benefits are they run cooler and last way longer. Kinda gives it that new Audi look
Got mine on ebay for around $38 ...link
