I put a set of DDM Tuning HIDs in my 2001 Sprint. I went with the 35 watt 4500K hi/low kit. Cost about $70 with shipping. They have a lifetime warranty. Best upgrade I ever did. I almost never use the high beams because there is so much light available with the low beam. Actually there is no difference in output, just a solenoid that moves the bulb from the low to high position. They also draw 20-25 less watts per bulb than the stock bulbs. I could have gone for the 55 watt kit, but that would be overkill most of the time. I had to go back to the stock bulbs once due to a control box failure and couldn't see anything. It was like they were not even on. Which was why I upgraded them in the first place. Much cheaper than any of the auxiliary light solutions out there.
You want to select the 9007 hi/low bulb, 35 watts and 4500k.
You will need to remove the entire front fairing to install them. I've got the ignitors and ballasts mounted above each headlight. The control box is mounted to the bottom of the black dash on the far right with velcro. I had to modify the wire harness to both extend the positive to the battery and also merge the two separate ground and extend them to the battery. I also had to modify the rubber cups that go over the back of the lights to seal them off. The hole is too small, so I had to make it bigger to fit the larger base on the HID bulb.
