I had my eagle eyes in my camaro since September 27th, 2010. I'm almost going on a whole year and I noticed the last few weeks my blue halo doesn't light up anymore. Here's a pic of them on my car. I get the white halo ring yet but no blue halo ring. It was the first issue I had with these lights. Here's a pic of the lights so you can understand what I'm talking about.
