What causes low beams to not work?
Solution: If both headlights aren’t working, it’s unlikely that a bulb is at fault. 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.
Are high beams and low beams the same bulb?
Most modern vehicles have a single bulb with two filaments. Some cars (mostly higher-end vehicles or performance vehicles) do have separate bulbs for their high and low beams. Generally, you’ll have a standard halogen bulb for low beams, and then an HID bulb for your high beams. These are not interchangeable.
What do low beams look like?
The “low beam” symbol looks like a rounded triangle or capital letter “D.” Downward-slanted lines extend out from the flat side of the shape. The “fog light” symbol utilizes the same shape and has downward slanting lines like the “low beam” symbol.
Why do high beams work but low beams don’t?
This is the most common reason we see for why a car’s high beam headlights work but the low beams don’t. The normal headlights are on far more often than the high beams, so the low beams burn out more frequently. Some vehicles have entirely different bulbs for the high beams, and other models have headlights with two different filaments.
Is it possible to fix a bad low beam headlight?
Fortunately, fixing a bad low beam is a straight forward process in the majority of vehicles that can be done by most people without just a few hand tools. If replacing your headlight bulb does not work, there may be an electrical issue in your vehicle that should be addressed by a professional. Identify a blown out bulb.
What to do if you drop a low beam light bulb?
Protect your bulb from this by wearing gloves or using a tissue any time you come into contact with the glass of the new low beam headlight bulb. Be careful not to drop the bulb as you remove it from the package. If you touch the bulb, use rubbing alcohol and a paper towel or rag to wipe it off.
Is it safe to drive with high beams on?
No one wants to be driving along at night and have their headlights go out. In many cases, the high beams will still work when the regular headlights stop, but it’s just not safe to drive around with your high beams potentially blinding other drivers.
