Alaska is not the same as the lower 48 in terms of road hazards and driving conditions. In the Anchorage corridor there are billboards along the highways with a moose counter -- how many collisions for the year. the number is usually in the 350 - 400 range by the end of the year. You'd think that after the first 250 or so people would begin to pay attention, but they still don't see these 1500# walking guardrails, and many are killed. I hve weaved my motorcycle through as many as 15 bears a mile along somestretches of northern highway. I've encountereed downed trees and landslides.
One solution to the carnage is lots of light. I run two hi/lo 55w HID projectors (not conversions) as aux lights on my trike. on high beam they will bbq a moose at two miles. ANYTHING reflective will reveal itself from as far away as the road is straight. I can pick out road markings, bunny eyes, broken glass, and buffalo with equal ease. On low they are about the same as halogen. The trick is to aim them for effect on hi beam and courtesy on low beam, and then use the [censored] dimmer switch. Nobody coming at me wants to ee that, and I don't want to be 'that guy' in these discussions.
Having lived 30 years in Alask and now touring the lower 48, I opine that in Alaska they do a much better job of choosing, aiming, and using light than 99% of the bozos down here. You CAN have good light, and you CAN put enough downrange to hurt oncoming drivers -- but nobody needs to know if you do it right.
