You can get a 580 wedge fitting LED for about £7each but i dont know how long they would last as a DRL i think they are for a stop & tail application but could be worth a try.

Agree with you totally about the DRL's being too yellowish especially after I installed a set of the Philips BlueVision Ultraheadlight bulbs. I found the following w21/5w MTEC Xenon Super White which I've ordered a set of to try out.
I saw those but passed them up because they're only single wattage (5w), not dual like the originals (21w/5w). It also stated "for interior use only" on the box. Plus on that ebay page it warns about many other possible problems such as canbus or dashboard warning lights.
Let us know how they work out, I'm especially curious as to what they do when the light switch is in the off position (DRL) while the car is running.
I have been doing a load of research on this and have reached the conclusion that I need to get a life.
The type of bulb used in our cars is known as a T20, a 580 or a 7443 and is a 5w/21w. The same bulb is used in some Alfa Romeos, Vauxhall Corsa's and Insignias, so their owners club sites have revealed a lot of useful information.
The main bulb which these people have tested and opted for is the Polarg M13 which is made of blue glass and gives off a very white xenon-effect light. The downside is that they are nearly impossible to find in the UK and are being ordered from the US.
This is an alternative, it's not the genuine article, but comes from a reputable trader.

They came in the mail today, changed one to make a comparison and WOW, what a difference..!! When the headlights are on, the DRL's are in the 5w position so they emit a whiter (but somewhat subdued) light which does make the Philips BlueVision Ultra headlights stand out but when the headlights are off and the DRL's are in the 21w setting then WOW... BRIGHT WHITE they are..!! I highly recommend these.
Which type of MTEC 21W/5W Xenon Super White DRL's do you
have? The closest I have come to finding them are MTEC 380 P21/5w S25 (1157)
Super White Xenon bulbs.
It's not a 21W/5W, they are the MTEC W21/5W T20 21/5W Xenon Super White. Here's the website I bought them from here in Switzerland (sorry, it's only in German).
I might add if you're changing the DRL bulbs just after they have already been running for a while, watch out, they're hot..!!
I'd like to change the DRL bulbs since I am changing the other bulbs up front! Has anyone in the UK changed the DRL bulbs yet and if so what did you replace them with/where did you buy them?
