The bulb could simply have blown, which is easily remedied. Many car part stores will stock the bulb. ... A faulty high beam relays could stop your high beams from working.

Why is my high beam not working on one side?
You'll need to replace the bulb, switch, or relay. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
Why does only one side of my headlights work?
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner's manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
How do I know if my high beam relay is bad?
Headlights doors don't give way:
This is one of the first and most common signs that your relay is bad. When the doors of your headlights do not give way or open, it is because the relays are not producing enough power to even open the headlight door.
Why is my high beam not working?
By far the most common reason your brights will stop working is from a blown fuse or a bad relay. ... Or, it could be a bad relay. If the headlight relay has failed, it may not respond when you attempt to switch the high beams on. Replacing the relay should restore the system and get your high beams working once again.
Why would both headlights go out?
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.
Can a bad relay cause one headlight not to work?
Headlight Fuse or Relay
If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.
Why do my high beams work but not my headlights?
Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams. If the fuse goes bad, you likely won't have any headlights at all.
Can I drive with high beams on?
While it is not against the law if you drive around with your high beams on as long as you follow the required distance and proper dimming of light or using low beams (low beam lights), improper high beam headlight usage comes with penalties.
Can you put high beam bulbs in low beam?
The high beam bulb may not fit into the reflector of the low beam. Yes, the circuit is able to power a high beam bulb just fine.
How do I know if my headlight sensor is bad?
Sensor failure results in the headlights illuminating during broad daylight when not needing to be on, or the ambient light sensor could have worn out. Whichever the case, either replace the entire windshield, or replace the headlight sensors.
How do you check a headlight relay?
Open the hood, locate the fuse box with the headlight relay or relays, and open it. Put your ear close to the relay and listen. Alternately, you can wedge the handle of a long screwdriver into your ear, and touch the screwdriver point to the relay. You can hear the relay click though the screwdriver like a stethoscope.
Why do my brights randomly turn on?
Your turn signal and high beams are working on the same switch. If you push the switch up and down, it activates the turn signals. If you move the switch in towards you, it activates the high beams. ... I recommend replacing the turn signal switch on the steering column.
Is there a high beam fuse?
High beam fuse – A blown high beam fuse is easily fixed, but repeated blown fuses will require further investigation to find the cause of the excessive current. High Beam Relay – This is usually powered by the headlight switch and in turn powers the headlights.
Why are my brights not bright?
The most common reasons why headlights don't get bright enough are that they either a lack of voltage in the circuit, the wrong size bulb, or the lens of the headlight is oxidized or faded. ... If that is fine then the lens on the headlamp may be faulty.
