I have a 2005 Subaru WRX. Over the past few weeks my lights have been flickering. Not just one light but all lights at the same time so I'm fairly confident that it's not wiring. Today my radar detector started giving me low voltage warnings. My battery is less than a year old and it's a top of the line one so I do not think that is the issue. Do you guys think it would be the alternator? Or is it some voltage regulator? The car is driving 700 miles on Monday so I'd prefer if it makes it the whole way. I've never had any problems at all with the car. Anybody got anything?
