I used Diode Dynamics inside and out for my G37 and was very impressed so obviously I wanted them for my vette. I purchased new amber day time lights from them and they were so dull I got pulled over because the cop though I didn't have them on. The factory bulbs were 10x brighter and cheaper. I also put in a set of their fog lights too. I got mabey 10 hours out of one and it was done. I also ordered their interior map lights (for the rear mirror) and they didn't even fit, totally wrong bulb type, though I see now they have corrected their website for future customers. This plus getting it shipped/returned to the states was a huge hassle. I went with Amazon after that and am very happy so far.
