After months
of normal driving with no problems, my 2003 Honda Civic EX check engine light came on during a long trip.
Because there is no brittle filament inside a xenon HID bulb to break or burn out, the head lamps typically last up to three times longer than halogen head lamps (3000 hours versus 1000 hours of continuous operation, which is equivalent to 5 to 10
years of normal driving)
While this might pose challenging in technical off - roading, I got acclimated to it within a day or
so of normal driving.
leading to the conclusion that this relatively small amount of electric power would be able to cope with 70 - 85 %
of normal driving, only aided by the combustion engine during start up and when extra energy is required for acceleration and hill climbing.»
