An information display board system especially adapted for use by travelers and tourists along an interstate highway. The display board is located at a rest stop or other location readily accessible by road travelers and displays a map of the road along which it is positioned and a listing of hotels/motels, points of interest and other lodgings in the region. ID/status indicators are provided which illuminate in one color, i.e., green, to indicate room availability and illuminate in a different color, i.e., red, to indicate room unavailability. Road alert indicators are positioned along the road map and are selectively illuminated to indicate delays or other road conditions. The illumination of the ID/status and road alert indicators are remotely changeable by hotel operators and the road authority, by directly calling a board manager. The board manager includes communication hardware in the form of a programmable computer and telephone control circuitry. A board manager receives information from the hotel operators and road authority as well as a central operator and controls the updating of the display boards via the communication hardware. Background information about the hotels and road locations can also be entered by the central operator and stored in the computer for later display to the operator.

A high-instantaneous, low-average current ballast is used in an accelerated weathering apparatus. The ballast includes a DC voltage generator or front end, to generate a high DC voltage, which produces a charging current to charge an arc capacitor. The energy on the arc capacitor is selectively released into a xenon lamp as short, high-current pulses. A starting transformer acts to strike an arc in the lamp. A switch is connected between the capacitor and the lamp, and is used to control generation of current pulses developed for the xenon lamp. A timer is implemented to control operation of the transformer and switch to selectively generate the current pulses for the xenon lamp.
