Subaru headlights may frequently blow out due to several factors, including issues with the vehicle's electrical system, such as voltage spikes or poor grounding. Additionally, using incorrect wattage bulbs or installing them improperly can lead to premature failure. Environmental factors, like moisture or corrosion in the headlight assembly, may also contribute to the problem. Regularly checking and maintaining the electrical connections can help mitigate these issues.
you need to replace the fuse for the headlights.
Bad voltage regulator
There is a voltage regulator located on the internals of you alternator replace the altenator. Voltage regulator keeps voltage constant and stops spikes in power output, this is what is causing your headlights to blow.
It might be because of moisture. Mine would go out every time it rained. I had my mechanic put a new silicon seal on the headlights and that solved it for me.
there are several possibilities, first: the fuse that provides power to the headlights could be blown out. second: the headlights could be burnt out. the other possibilities would require a professional diagnostics by a Subaru technician.
left side headlights dim--why?
Headlights on a Renault Clio may keep blowing due to several reasons, including faulty wiring or connections that cause short circuits, a malfunctioning headlight relay, or an issue with the vehicle's electrical system, such as overvoltage. Additionally, using incompatible or low-quality bulbs can lead to frequent failures. Regular inspection of the electrical components and using the correct bulb specifications can help mitigate this problem. If the issue persists, consulting a professional mechanic is advisable.
There are no 2009 Subaru models with 2WD.
The voltage is lacking when you are not pressing on the gas... while pressing on the gas.. you are giving the headlights more electricity...
When it is raining during the day you should always keep your headlights on.
Subaru owners keep their vehicles an average of three years.
