I'm running Silverstars but they don't look that different than the stock GE's at DRL voltage. They are a bit whiter at full voltage.
Daytime Running Lights are there for safety not looks. Your vehicle is more noticable to others in traffic so you are less likely to get hit by someone talking on the cell phone for example.
I'm not thrilled with how DRL look with my DDE's but I'm certainly not turning them off. It would be like turning off my brake lights because I didn't like the way they looked. There's a limit to what I'm willing to do for esthetics and that limit is reached when safety is an issue.
Just my 0.02.
