Please choose the correct ending to complete the given sentence: Cars & Other Vehicles: [header] How to fix a low beam headlight [title] Identify a blown out bulb. [step] You can often tell when a headlight blows out while you're driving, but confirm which bulb has actually blown out by leaving your headlights on and getting out of the vehicle to check. Then get back in your vehicle and turn on your high beams.

Ending1: [substeps] If your headlights stay on, they may not produce enough power to output the voltage that is responsible for the blown out bulb. If the blown out bulb you see has a blown out hole in the center, you may need to get to a mechanic to fix it. Ending2: Look for the bright green indicator and confirm that the battery is off by looking under the vehicle's bumper. [substeps] There may be partially blown out bulbs that you can see with good night vision. Ending3: Check the headlight periodically to make sure it's where you want it to be. [substeps] Even while you're driving, check behind the vehicle first to make sure it hasn't been blown out and isn't in a puddle or other dangerous place. Ending4: Some vehicles use a single bulb for both high and low beams while others do not. If the high beam on the same side is also out, it may be one bulb.
