Here's an odd set of questions...
Willys-Overland, its successors, and other jeep manufacturers have used several ways to protect the headlights on their vehicles. A few of these methods have been copied by aftermarket manufacturers to protect headlights on more modern jeep vehicles.
This model protects the head lamps with deep, round bezels attached to the grill.
These two models had the lights attached to a rotating assembly mounted behind the grill.
This model had the headlights mounted behind a heavy gauge wire which was some of the only steel in the front end of the jeep.
And this model had a similar steel wire over the lights on a "traditional" jeep grill.
