Hi everyone.

So, over the past 6 weeks, I spent a lot of time trying various LED replacement bulbs for the DRL's/Turn Signals. (Mind you, that my car is a 2006, and the headlamps are in near new condition, no burnt lenses). I did this, to be proactive to prevent any future damage. To my dissapointment, NONE of the canbus/error free ones work. They all failed, and they are all VERY HOT, if not hotter than the halogens. So, I decided to try the external load resistor with standard LED bulbs. They worked, perfectly, but, I think it's pure stupidity to have that much heat dissapating from resistors. Very inneficient. So, I pulled it all out and put the halogen bulbs back in, and will drive with my DRL's off until I can find (what I feel to be) an acceptable solution. Which leads me to this question: Does anyone know if the relay(s) in the XLR can be modified to prevent the hyperflash situation so as to not have to install the hot resistors? I found an article for someone who modified their relay in an Acura TL, and there seems to be some relays on the market that do this as well. Is this possible in the XLR? I'm not so savy to figure it out on my own, but there's got to be a better way. There just has to be. Here's the article I found in regards to the TL:
