Why do my low beams work but not my high beams?

Why do my low beams work but not my high beams?

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.

Does Jeep Grand Cherokee have auto high beams?

The SmartBeam system provides increased forward lighting at night by automating high beam control through the use of a digital camera mounted on the inside rearview mirror. This camera detects vehicle specific light and automatically switches from high beams to low beams until the approaching vehicle is out of view.

Do all headlights have high beams?

High beams and low beams are two different parts of your car’s headlights. Both high and low beam headlights are important safety features on your vehicle, but many drivers don’t know whether their car uses different bulbs for high and low beams. The truth is, it all depends on the type of car you drive.

Do HID lights have high and low beam?

However, headlights are available that can be switched between high and low functions. Certain HID lights, for example, are made with both high and low beam options, so drivers can switch from one to the other according to the needs and appropriateness of a particular time and setting.

Where should my headlights be aimed?

The top of the low beam shining on the wall should be at or slightly below the height of the center of the headlight lens for most vehicles. You should expect the light pattern to be higher on the right side (passenger side) to illuminate road signs and lower on the driver’s side to prevent blinding other drivers.

Just discovered that both high beams are not working. Regular lights ok. When switch to high beam both go off. I know some bulbs have two filaments, is this the case for this car?

Why is the head light switch out on my Jeep Wrangler?

I suspect the latter only because both high beams are out. Once you check the voltage like missileman says, try to back track the wiring to see where the voltage break is. This can be a PITA. The headlight switch is a common problem on Wranglers, but very easy to replace. The high beam switch is not too bad to replace.

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.

Why is the head light on my Jeep Rubicon not working?

My sons Jeep had a similar problem, turned out to be at the fuse box, where the wire going out from the fuse looked like it was intact but when I pulled on it with needle nose pliers it was loose, had corroded away. Not sure about the Rubicon, but on the Wrangler it is easy enough to get the fuse box off and check underneath.
