i dont know but if i remember i think G series are more hyper white than the regular ones. i have the regular Polarg BI hybrid bulbs and they start fading a little to yellow. And when you have your parking lights on they are pretty much yellowish until they start blinking. And i think maybe the G series will always be hyperhite but im not sure. Try getting Cuzo bulbs. They have a very nice color. But my low beams did burn out in 4 months but the cuzo reverse lights i have looks good and are still going strong 6months already.
