HIDs are made according to the stock bulb size, so once you know what bulb the Buick Regal uses, you just buy the HID kit and install them. For the most part, it's a pretty simple plug and play application.I would... do they make them for Regals?
Some of the higher end cars do come with stock HIDs. It would be nice if the Regal or the Regal GS came standards with HIDs - pretty amazing. And having the HIDs installed at the factory will ensure that the installation is completely properly and that they are aimed well.Agreed... why don't cars in general have HIDs as stock?
