Darker Commutes After Daylight Saving Time Ends: A 10-Minute Headlight, Wiper and Visibility Check

When should you replace your wipers and check your headlights?

Short answer: replace windshield wiper blades every 6 to 12 months, and check every bulb before Daylight Saving Time ends on Sunday, November 1, 2026. That night, Sacramento's sunset jumps from 6:06 pm to 5:05 pm. Quality Tune-Up Arden Way, at 2545 Arden Way, sees the evening commute go dark overnight.

The clocks fall back at 2:00 am on November 1. On Saturday the sun sets at 6:06 pm. On Sunday it sets at 5:05 pm, and by November 30 it's down at 4:45 pm. That puts the ride home on Business 80, Arden Way and Fulton Ave in the dark for most people who get off at five.

It also lines up with the first real rain. Wipers that sat through a dry summer get their first workout the same weeks your headlights start doing all the work. Below is the 10-minute check we'd do in your driveway. We'll also cover when to bring it to our Arden Way shop at Fulton Ave or our Northgate shop at West El Camino.

Is driving after dark really more dangerous?

Yes. About half of U.S. traffic deaths happen at night, even though only about a quarter of driving happens after dark.

That's from the Federal Highway Administration. A 2007 NHTSA research note, using 2005 crash data, put the nighttime death rate for people in passenger vehicles at about three times the daytime rate. Drunk driving and speeding are a big part of that. So is plain old not being able to see.

You can't fix the other drivers. You can fix a dim bulb, a hazy lens and a wiper that smears right where you need to look.

What does California law say about headlights and wipers?

If your wipers are running nonstop because of rain, mist or fog, your headlights have to be on. That's California Vehicle Code section 24400(b) and (c).

The same section requires headlights during darkness. The Vehicle Code defines darkness in section 280 as a half hour after sunset to a half hour before sunrise. It also counts any time you can't make out a person or a car 1,000 feet away. Thick tule fog on Hwy 99 or I-5 can meet that test at any hour.

So on November 1, the law wants your lights on by about 5:35 pm. By the end of the month it's closer to 5:15 pm. If your car has an Auto setting on the headlight switch, leave it there.

Two more rules worth knowing. Section 24400(a) says a car needs at least two headlamps, one on each side. Section 24252 says required lights have to be kept in good working order. One headlight out isn't a style choice.

The 10-minute headlight, wiper and visibility check

Do this at dusk in your driveway or a parking lot, with the engine running. A second person helps with the brake lights, or back up to a garage door or a store window and use the reflection.

1. Low beams (1 minute). Both on, both the same color. One yellow and one white usually means one bulb was replaced and the other is old.
2. High beams (1 minute). Flick them on and off. Both sides should jump.
3. Taillights and brake lights (2 minutes). Check all of them, including the center brake light up high.
4. Turn signals and hazards (1 minute). Walk around once with the hazards on. A fast blink on the dash usually means a bulb is out.
5. License plate light (30 seconds). Easy to forget. Vehicle Code section 24601 requires the rear plate to be lit during darkness.
6. Headlight lenses (1 minute). Look for yellowing, haze or moisture inside the housing.
7. Wiper blades (2 minutes). Lift each blade and run a finger down the rubber. Look for cracks, nicks and rounded edges. Don't forget the rear wiper.
8. Washer spray (30 seconds). Both jets should hit the glass, not the roof.
9. Defrosters (1 minute). Turn on the rear defrost and the front defrost and make sure both work.

If you find a burned-out bulb on one side, plan on replacing both. That's what our headlight post recommends, and it keeps the color and brightness matched.

How do you tell your wiper blades are done?

If they streak, chatter, skip or leave a haze, they're done. AAA puts the usual life of a blade at 6 to 12 months.

Sacramento is hard on wipers in a specific way. NOAA's normals for Sacramento Executive Airport show zero inches of rain in a normal July and only 0.04 inches in August. Then October averages 0.85 inches and November 1.66. Your blades bake on the glass all summer, then get asked to work in the first storm.

• Streaking. Thin lines of water left behind. The rubber edge is worn or dirty.
• Chattering or skipping. The blade hops across the glass. Sun-hardened rubber is the usual cause.
• Squeaking. The blade isn't gliding anymore.
• Cracks or a torn edge. You can see these when you lift the blade.
• A band you can't see through. If it sits right in your line of sight on the 50 at night, replace the blades now.

Before you blame the blades, clean the glass. Wipe the rubber edge with a damp paper towel and wash the windshield. Tree sap and road film can make good blades act like bad ones. If it still streaks, replace them.

Dim, yellow or hazy headlights: is it the bulb or the lens?

If the light looks yellow and the lens is clear, it's usually the bulb. If the lens itself looks cloudy, it's the lens.

Halogen bulbs fade as they age, and they rarely fail on both sides at once. That's why one side often looks whiter than the other.

Plastic lenses are a different problem. Years of Sacramento sun break down the coating, and the outside turns yellow and hazy. A restoration kit from the parts store can clear up surface haze. If the haze or moisture is inside the housing, cleaning the outside won't fix it, and the headlight assembly usually needs to be replaced.

Not sure which one you have? Ask at the counter while your car is in. A tech can tell you in a minute whether it's the bulb, the lens or the aim.

High beams, fog lights and aim: what's legal and polite?

Use high beams on dark roads, but drop to low beams within 500 feet of oncoming traffic and within 300 feet of a car you're following. That's Vehicle Code section 24409.

• In fog, use low beams. The California Driver Handbook says high beams reflect back and cause glare. It also says never drive with only parking lights or fog lights on.
• In rain, use low beams. Same handbook, same reason.
• Getting flashed a lot? Your headlights may be aimed too high. A heavy load in the trunk can tip the beams up too.
• Can't see the lane lines? The aim may be too low, or the lenses are hazy. Either way it's worth a look.

Our older post on vehicle safety tips for longer nights has a quick walk-around list too.

Rear defrost, washer fluid and cabin filter: what else should you check this fall?

Three quick ones: the rear defrost, the washer fluid and the cabin air filter.

• Rear defrost. Turn it on for a few minutes on a cool morning. If a few lines stay fogged, a grid line may be broken.
• Washer fluid. Top it off with real washer fluid, not plain water. The fine print on our oil change coupons includes a washer fluid top-off.
• Cabin air filter. A clogged one slows airflow to the windshield, so the glass takes longer to clear. Our air filter page explains both filters, and we check them any time your car is in for service.
• Inside of the windshield. Clean it. The film on the inside glows in oncoming headlights.

If the car fogs up and won't clear, run the A/C with the defrost. The A/C pulls moisture out of the air, even in winter. That works on most cars.

Where can you get lights and wipers looked at near Arden-Arcade or Natomas?

You can ask about your lights and wipers at any of our six shops. Two sit right on the evening commute routes this post is about.

Common questions

How often should I replace windshield wipers in Sacramento?

Every 6 to 12 months, per AAA. Sacramento summers are hot and nearly dry, so blades often harden by fall. Check them before the first storm and replace them if they streak, chatter or skip.

Is it illegal to drive with one headlight out in California?

Yes. Vehicle Code section 24400 requires at least two headlamps, one on each side, lit during darkness or bad weather. Section 24252 requires required lights to be kept in good working order.

Do I need my headlights on during the day in the rain?

Yes, if your wipers are running continuously because of rain, mist, snow or fog. Section 24400 counts that as inclement weather, and your headlights have to be on.

Why are my headlights foggy or yellow?

Most headlight lenses are plastic, and years of sun break down the outer coating. Haze on the outside can often be polished off with a restoration kit. Moisture or haze inside the housing usually means the assembly needs to be replaced.
