I have been reseraching DRLs for a while - to fit them to both my Lancer and Commodore.
The best DRLs bar none are made by Hella (who also make the lights for Audi). They are ADR compliant.
If you are serious about getting DRLs for visibility, you need something that complies with ADR 76/00, which requires DRL light output between 400 and 800candela. Studies have shown that the optimum output is 1200cd, however, the policy in Australia is behind the times. To qualify properly as DRLs, the lights have to turn off when the headlights are switched on at night.
If you are going to install the lights, you need to make sure they are at lesast 600 mm apart and at least 250mm from the ground.

Check part nos. 5608, 5607 and 5610. You can't beat them. They cost a bomb though - the cheapest I found 5607 for was $370, 5608 was $430. But if you want DRLs to a. be safe and serve their purpose and b. look good - you need to do it properly.
In Europe, Hella has just released a product called LEDay Flex (
http://www.tagfahrlicht.com/index_de.html) - the link is in German, but you get the idea. They are selling for about 200 euros a set at the moment, not including postage. I have contacted Hella Australia and at the moment they have no intention of bringing them here.
I like what Deano and Andros have done, but they aren't DRLs. They look good but do not really aid in increasing the car's visiblity. True DRLs are more visible during the day than low beam headlights. Low beam headlights are visible about 100 metres away during day time. DRLS aimed correctly and installed at the right level are visible up to 170 metres (@ 800cd).
I have also found a manufacturer in China who produces imitation Hella LEDayLine DRLs. They are Euro E marked (E4) so would be ADR compliant. I have sent them a couple of emails over the last couple of weeks and although they are really a wholesaler, they said they can send me some over. They are about $80US + $45US for freight per set!

DRLs are the way of the future! They are becoming mandatory in Europe from 2011. Audi's research has concluded that their LED DRLs have saved something like 10 million litres of fuel in the last 5 years ebcause of their low current draw and less stress on the car's alternator.
So yeah, you can probably tell I like DRLs, just got to find the right ones and at a good price and I will be putting them on for sure!
