Got the K5 bulbs installed no problem and no issues. Well, one issue, and maybe it's just my car, but it has to be OFF when swapping the bulbs or the computer gets confused or something. I tried with it on and could not for the life of me get anything but amber to light up. Finally just decided to turn it off and in frustration tried again and boom...it worked. Whatever...lol.
The color of the bulbs was a bit blue compared to everything else, and they weren't quite bright enough to run as DRL's, which is my whole plan, so I went back to the first type of bulb I ordered, which, I hate to say it but I'm being honest, are way brighter. They are very similar to what you have for the high powered reverse bulbs.
