Only if you're leaving them on all night. Seriously, look for other problems such as an old battery, low water level, bad alternator, or some other type of drain (glove compartment light for example). I doubt the HIDs would be the source of the problem, as the demand on the electrical system should not be extraordinary. My apologies to the original poster for derailing the thread.
