Like I posted, they are legal - however - as the statute says:

No person shall use or attempt to use or possess any jacklight for the purpose of taking any deer. For the purpose of establishing a prima facie case under the provisions of this section, a jacklight shall be construed as any artificial light when used in conjunction with any rifle larger than a twenty-two long rifle, or with a shotgun and ball shells or shot larger than No. 2 shot or with a bow and arrow or crossbow, in any area frequented by deer or where deer are known to be present, or in any deer habitat, and possession of such articles in any such place, or any road, lane or passageway adjacent to such place, by any person during the period from one-half hour after sunset to sunrise shall be prima facie evidence of a violation of this section.

If you are in deer habitat 1/2 hour after sunset and you have a laser sight attached to your bow/rifle/shotgun/pistol - even if it's not turned on (or possesses any jacklight), you would technically be in possession of jacklighting equipment. If you want to go the laser sight route I would strongly recommend that you be at your vehicle with the rifle/shotgun/bow/pistol in your vehicle at 1/2 after sunset. Right now we give some leeway with people who stop hunting at sunset and are walking out of the woods after that. Laser sights were not invented when the laws were enacted so nobody considered them.
