A: Unfortunately there is not a direct bolt in HID kit for the Raptor 700. The most common, is to retrofit an H6M bulb style kit. This will require modification to your stock wiring, please do some research before attempting to install this. The other option is to add additional lighting and leaving the stock headlights the way they are.
A: Unfortunately Polaris uses a proprietary bulb you can not buy anywhere but from Polaris. There are forum threads if you do a google search, where customers have modified their existing housings and wire harnesses to accept other bulbs. Unfortunately there is not a kit offered in HID or even replacement bulbs, other than the OEM bulbs from Polaris.
