Military Hummers don’t have a keyed ignition switch. Instead, a three-position lever controls off, run, and start (the high-tech anti-theft system involves pulling a steel cable out from under the dash, wrapping it around the steering wheel, and securing it with a padlock). The light switch is also military spec, and it’s located just below the ignition switch. The indicator to the right of the ignition switch is an air-filter restriction gauge, something that’s not found inside the civilian version. A regular keyed ignition on the steering column is used on civilian units.
