Headlights vs High Beams Symbol
The headlight symbol has angled lines, and the high beam symbol has straight lines pointing ahead, usually glowing blue.
The two symbols share a shape but point a different way
Both symbols are a version of the same icon, a half circle meant to look like a headlight with beams coming off it. The regular headlight symbol, usually green or amber, shows lines angled downward or outward, because low beams are aimed down and to the side so they light the road without blinding anyone coming the other way.
The high beam symbol is the same half circle but the lines point straight out, horizontal, and it's almost always blue. That straight line is the point. High beams throw light flat and far down the road instead of angling it down, which is exactly why they're brighter and why they're also the ones that blind oncoming drivers if left on too long.
Dashboard symbol colors follow a rough pattern across most cars. Blue usually means a feature is on and working as an extra, which is why high beams show blue. Green usually means a standard function is active, which is why regular headlights show green. This isn't a rule enforced by anyone, just a convention most manufacturers follow, so always check your specific car's manual if a color looks different than you expect.
Where this gets confusing is that some dashboards layer the two symbols close together, or use nearly identical icons with only the line angle different. A new driver glancing down quickly can mix them up, especially at night when every second of attention matters. That's less about intelligence and more about unfamiliarity, the same way any new symbol takes a few uses to recognize instantly.
What to point out when you teach your teen this
- Angled lines mean low beams Lines pointing down or to the side mean regular headlights are on. This is the default for all normal driving, including most night driving with other cars around.
- Straight lines mean high beams Lines pointing straight ahead, usually in blue, mean high beams are active. Teach your teen to glance down and confirm this before assuming low beams are on.
- Blue means an extra feature Blue dashboard icons generally flag something extra turned on, not a default state. Use this as a quick visual cue to check for high beams at a glance.
- Mixing them up blinds others Leaving high beams on around other cars is the most common beginner mistake. Practice turning them off manually in a parking lot before your teen drives at night.
- Manuals confirm your car's icons Icon design varies slightly by manufacturer, so the owner's manual settles any doubt. Look this up together once instead of guessing from memory while driving.
Teaching this now versus letting your teen figure it out alone
If you do
You sit with your teen for five minutes, point at the dashboard, and show both symbols lit up in the driveway. They learn to check the icon before pulling out at night, out of habit, and high beam mistakes basically disappear within the first few weeks of solo driving.
If you don't
Your teen guesses based on vague memory the first night they drive after dark. They either leave high beams on too long around other cars or avoid using them entirely, unsure which icon is which, right when visibility matters most.
Once you've got the basics covered for your teen, compare quotes to see what adding them actually costs across insurers.
The first night drive after getting a license
A parent lets their newly licensed teen drive them home from dinner after dark, the teen's first real nighttime drive alone at the wheel. On a dark road outside town, the teen reaches for what they think is the high beam switch and flips on the regular headlights instead, confused why the road still looks dim.
The parent calmly points at the dashboard, shows the blue high beam icon isn't lit, and talks them through pulling the stalk toward them to engage it. The teen notices the icon change from nothing to a blue beam shape, and the road lights up further down. They practice flicking it on and off at the next few empty stretches, checking the icon each time instead of guessing by feel. By the end of the drive, the teen is glancing at the icon automatically, the same way they'd check a speedometer, and the parent stops worrying about it being a habit they still need to build.
This is about teaching your teen to check the dashboard instead of guessing in the dark.
Why do my high beams sometimes turn on by themselves at night?
Many newer cars have automatic high beam assist, which switches between high and low beams on its own based on oncoming traffic and ambient light. If your teen sees the blue icon flick on and off without touching anything, this is almost certainly what's happening, not a malfunction.
Check your car's manual to see if this feature exists and how it's labeled, since it's often a separate setting that can be turned on or off independently from the headlight switch itself. If your teen's car doesn't have this feature, any beam changes happening without their input are worth getting checked by a mechanic, since that points to an electrical issue rather than normal behavior.
