Can a broken headlight switch keep the high beams on?
Most headlight switches operate by pulling the lever backwards and locking it into place to activate the high beam headlights. Over time however the switch can break, which can lead to issues keeping the high beam headlights turned on. A broken switch may still be able to turn the high beams on,…
What are the symptoms of a bad or failing headlight switch?
Issues with the high beams Another symptom of a bad or failing headlight switch is issues operating the high beams and more specifically, issues keeping the high beam engaged. Most headlight switches operate by pulling the lever backwards and locking it into place to activate the high beam headlights.
How does a headlight switch work on a car?
Most headlight switches operate by pulling the lever backwards and locking it into place to activate the high beam headlights. Over time however the switch can break, which can lead to issues keeping the high beam headlights turned on.
When do you need to replace a headlight switch?
The switch usually controls the vehicle’s interior lights, the running lights, the low beam headlights, high beam headlights, and in some vehicles the automatic headlight system. As with any electrical switch, with regular use, it may eventually wear out and need to be replaced.

Are there any cars that still have sealed beam headlights?
It’s interesting to note that while all cars sold in the U.S. ditched sealed beam headlights a while ago, some base-model commercial vehicles continued to use them in their least-expensive variants through the 2017 model year. Today, there are no new cars or light trucks sold with sealed beam headlights in the United States.
When did sealed beam headlamps become legal in the US?
1956 Chevy Bel Air. 1957: The U.S. law changed, and began to allow the use of FOUR sealed beam headlamps, each lamp measuring 5 3/4″. Two would serve as the low beam, and two as the high beam. Each lamp has two electrical prongs at the rear. American carmakers quickly began to transition from 2-headlamp designs to 4-headlamp designs.
Is there a problem with the Headlight high beam?
You could remove the headlight and then check the voltage at the high beam terminal when high beam is selected. If it has 12VDC then it’s a headlight bulb problem. If not…it’s a problem with the headlight high beam control.

What to do if your high beam light is not working?
Check your owner’s manual to be sure which kind of high beam bulb you need and get familiar with the fuse box in case the high beams stop working. Finally, practice using a digital multimeter so you can rule out electrical problems before replacing other components. A blown high beam headlight bulb, an easy fix.
How does a high beam light bulb work?
Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.
Why does the high beam light come on when the low beam is not on?
Both may burn out without you realizing it. If the high beam indicator in the dash comes on when your HI/LO switch is in the low position, AND your low beam headlights are not on, then you have a dirty or faulty combination switch. The Hi beam indicator light in the dash works this way: It has a permanent path to ground.
Why are there two fuses for high and low beams?
According to the electronic manual (not the owners manual), the same fuse is used for high and low beams. The reason for two fuses is one is for left and one is for right. There are also two headlight relays (left and right) but they do not control the switching of low or high beams either (same story as the fuses).
When do you need to replace the headlight switch?
If the high beams, daytime running lights, or headlamps are not working consistently, you may need to replace the headlight switch. 1. Issues switching between modes
Why do you need a relay for a headlight switch?
By using a relay we move the high current switching away from the headlight switch so that the switch only sees a small current – in the range of a few thousands of an amp. This solves part of the problem. You will need two relays – one for low beam and one for high beam.
