Oh wow, that's a lot of kit. Yeah, I'd probably end up using individual boxes for each ballast, and the light pattern pics wouldn't help me much anyways, as the HF lights are different anyways. It's just difficult to predict how an HID bulb will affect the light pattern of a given light due to the difference in how HID bulbs disperse light from the bulb. Knowing that the issue here is glare from the hood, I think I'll end up getting one set of the HF lights to test out the pattern, and if that's good, I'll get another set and mount them. Then, somewhere along the road, I'll get an H3 HID kit for 2 bulbs, and see if it work well with the HF lights or with the DayStar lights. That will determine what I need to do next.
PS. That Phillips head screwdriver looks like it's seen much better days.
