I've been running white 28-LED SMT bulbs in my headlight parking sockets as Daytime Running Lights for at least a year and a half - they are still a bit too dim for satisfatory use in the middle of the day, but are great for morning and evening drive times while the sun is low, or on cloudy days... but did you do some rewiring so yours are on without the tails?? I'd like to set mine up that way... ok, I see you explained that at the end of your post, maybe you could elaborate on what you did...
Right now I have 25-LED bulbs installed, the 28-LED's burned out a while back, the heat from the headlights so close-by does shorten their lifespan...
