Fragman88, if that was a certain airline from the fragrant harbour, that was because on the 744 it was found that the lense covers were cracking due to the heat from the lamps with them left on 24/7. The lense covers are now made from a different spec material and are less prone to the effects of the heat generated by the lamps and generally don't crack anymore.
If you can't see a wingtip during daylight on the ground turning the pos lights on is'nt going to stop anybody driving into them!!!
