For DRLs we all seem to have gone for MTEC Superwhite which I'll add a photo to show the results! Main/Dipped beam I went for Phillips X-Treme Power which are very powerful but not as White as I had hoped. I believe Osram Nightbreakers are your best bet Which a few members have, While your replacing the it's worth doing them all! I ordered the following:-
Main/Dipped = Phillips X-Treme Power H4
DRLs = MTEC Superwhite 380W T20
Sidelights = MTEC Superwhite W5W
Indicators = Phillips Chromed Bulbs PY21W
** After decription is the bulb/lamp fitting **
As I say await feedback on mains I highly recommend the X-Treme power they are incredibly powerful, the beam is alot whiter than the standard bulbs but more performance than style. But as for DRLs, Sidelights and Indicators the above are certainly the ones to go for.
Powerbulbs is a good place for the Main, Sides and Indicators. MTEC are found on Ebay
DRLS and Chromed Indicators Fitted
Attached the DRLs on a night and the Main/Dipped Beam from X-Treme power, As you can see the DRLs do give a tint of blue (infact the bulbs themselves are blue, But are different from the MTEC Cosmos Blue) Hard to get a good photo of the lights!!
Hope this helps
