I had the 18 SMD LED's that are most popular

No codes. There were ok, but not as bright as stock. The looked cool, but not really bright enough for DRL's more like Dusk/DawnRL's.
I just splurged and put these in tonight. They are the 12 Watt Eagle EYE SMT Tower.

They are brighter than stock and if I had to put a number on it, 3 or 4 times as bright as the 18 SMD LED's that I had.
Will have to watch for heat issues. No codes yet.
One thing I found is that it's damn hard to convey what these actually look like in a photograph.
The Eagle eyes are bluer than other LED, but not ricey. IMO.
Another description would be that if I get down on level with the lights, while the glow is consistent throughout the reflector, that forward facing led will spot my eyes.
I'm going to try to get a pic in full daylight to really show how bright they are.
