What would cause a headlight to keep burning out?
VIBRATION. Halogen bulbs and sealed beam headlights have very fine tungsten wire filaments inside that emit light when heated. Even under ideal conditions, the filament can break, leaving you in the dark. Vibration caused by driving over rough roads, potholes and bumps will reduce the filament lifespan.
Is it normal for headlights to get hot?
All light bulbs get hot when in use – it’s the nature of how they work. With the exception of LEDs and fluorescent bulbs, light bulbs work on the principle of resistance. Electric current is directed through the bulb. The filament is designed to resist the flow of electrons.
Do headlights burn out at the same time?
If you think about it, bulbs are designed to last about the same amount of time. If they are installed in pairs, then the secondary light which matches the first will most likely be on the road to death just as the first. This holds mostly true for higher output lights, like your headlights.
How do you tell if a headlight bulb is burned out?
One of the first symptoms of a bad or failing headlight bulb is dim headlights. Over time headlight bulbs can wear out and begin to shine noticeably dimmer than when they were new. A dim headlight will not provide proper illumination and is also usually a sign that the bulb is approaching the end of its service life.
Can LED headlights catch fire?
The possibility of led strip lights catching fire is minuscule, even though they are hot to touch. Incandescent bulbs have a filament that emits excessive heat, the light sources can ignite a fire on overheating, but as LED lights produce light at a lower temperature, they don’t catch fire as easily.
Are LED lights hotter than halogen?
Are LED bulbs cooler than halogen bulbs? Yes they are. The majority of the energy that an LED bulb uses is converted into light rather than heat, which makes them much cooler to touch.
Why would both headlights go out at once?
Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. The cause: A burned out bulb, or a problem with the high beam switch or relay. The fix: Replace the bulb, switch, or relay.
Do brighter headlights burn out faster?
Different types of headlights have different life expediencies, so halogen, xenon, and other types can’t be expected to burn out at the same rate. Some replacement halogen bulbs are also significantly brighter than the OEM bulbs, and that increase in brightness usually translates to shorter lifespans.
Why are my Outback Outback headlights burning out?
Excessive vibration can break apart the delicate filaments inside the bulb. Headlights are designed to work with a specific voltage, so any electrical surges can fry them like a good piece of catfish. So all headlights burn out, but the 2010-12 Outback and Legacy fail at a much higher rate.
What causes a Subaru light bulb to burn out?
Light bulbs, whether they’re in a Subaru or your house, are going to burn out eventually. But what are the factors that lead to a bulb’s demise? Let’s get the most obvious reason out of the way first. The more you use your headlights, the quicker they’ll burn out. I dare you to challenge me on this.

Is there a recall on Subaru Outback Outback?
While not a recall, the program extended the vehicle’s original “new car limited warranty” for headlamp bulbs to 10 years from the warranty start date (regardless of mileage). It also confirmed that Subaru was aware of widespread premature headlight burn out in its 4th generation Outback and Legacy.
