I replaced the interior bulbs of my Cobalt with these Auxito LED bulbs and was very pleased with the results. These LED bulbs all worked, are noticeably brighter, with a pleasing daylight colour temp and they fit almost exactly the same as the OEM bulbs. There is no flickering or other weird LED artifacts. The hardest part was getting the various covers off and getting the OEM bulbs out (some are recessed and difficult to get a hold of and they get hot when lit so watch out!). Watch the "Doing Things Dan's Way" video on Youtube for some great tips. These also use a lot less power so there's less risk of running down your battery if they're left on. I would definitely buy these again.
