LIGHTBULB ON/OFF ANALYSIS

One of the issues that arises in most nighttime vehicle accidents is, "Were each vehicle's lights on at the time of the impact?"  In many cases, by analyzing the condition of the overall vehicle and the condition of the light bulbs, we can determine if a particular light was on or off at impact.  This can be useful in determining why a driver did not see a person or another object in the road. This analysis can also be used to determine if a vehicle was not visible because its lights were not on.
