This is from the Texas parks and wildlife web site:
Archery and Crossbows
(see Artificial light in Restricted Methods section)

Only the archery and crossbow equipment prescribed in this section may be used for taking game animals or game birds. Crossbows are not lawful for taking migratory game birds. The prescribed archery and crossbow equipment may be used during any general open season. Archery and crossbow equipment may not be used to hunt deer during the Muzzleloader-Only Deer Season. It is unlawful to be in possession of a firearm while hunting with a broadhead HUNTING point during the Archery-Only season, except a person licensed to carry a concealed handgun in Texas may carry a concealed handgun. NOTE: A firearm may be possessed in camp, in a motor vehicle, or while hunting lawful game other than whitetail or mule deer and turkey (e.g., exotics, feral hogs, squirrels).
