Improve Your Night Vision When Driving in TUCSON

Night driving in TUCSON is not as safe as daylight driving as evidenced by the increased accident rate at night. Much of that is simply because it's dark outside.

Visibility is important to safe driving. Ninety percent of our driving decisions are based on what we see. And at night, we just can't see as much as we can during the day. In fact, if you have 20/20 vision during the day, your night vision is only 20/50. To translate, that means that an object you can clearly see 50 feet away during daylight, only becomes visible to you at 20 feet at night.

Reaction time is also related to visibility. TUCSON motorists don't react to a situation until they see it. So at night, we're reacting to situations later just because it takes longer to see them. But we don't have to stop driving at night to stay safe. We just need to practice some preventive maintenance and vehicle care that will maximize our night vision.

The most crucial item that helps us see while driving at night is, of course, our headlamps. TUCSON drivers should ensure that their headlamps are as bright as they can be. Headlamps dim over time, but they do it so gradually that it's difficult to notice. Because of this, experts recommend replacing headlamps once a year.

That's good auto advice for TUCSON drivers, but it doesn't apply to all headlamps. Some vehicles use HID, or high-intensity discharge, headlamps. These are bright headlamps that are designed to last for the entire life of a vehicle. Depending on your vehicle, you may be able to upgrade to HID headlamps. Consult with your friendly service advisor at Garrigan's Auto Repair Shop to learn your options.

Most vehicles use standard or halogen headlamps. If you use standard headlamps, you might want to upgrade to halogen, which offers a brighter headlight. Halogen headlamps come in a variety of grades, so evaluate your options the next time you replace your headlamps and upgrade if you want a better light.

It won't do much good to upgrade or replace your headlamps, however, if your headlight lens is dirty or yellowed. Studies have shown that about 90% of the vehicles on the road have impaired headlights due to dirty or yellowed headlight covers. You should get into the habit of washing your headlights every time you gas up. Simply grab the window washer squeegee, run it over your windows, then swish it across your covers. No cost involved at all.

Plastic headlamp lenses yellow or become hazy over time. If your lenses have this problem, they can be restored with a special polishing process. You may be able to get this done at your TUCSON service center. If not, they should be able to tell you where you can.

Now, what good is a quality headlamp if you can't see through your windshield? Your windshield needs to be clean and streak-free if you plan on driving at night in TUCSON. You should also keep your windshield washer fluid replenished and your wipers in good condition.

Wiper blades should actually be replaced twice a year. The changing of the seasons at spring and fall, or Daylight Saving Time, can be a good reminder to do this. And while you're at it, fall is the perfect time to replace your headlamps. Those long winter nights add up to a lot more night driving for people in TUCSON.

Stay alert. Stay awake. And keep those headlamps burning bright.

Your Vehicle's Hissy Fit (AC System)

When you hear hissing sounds coming from your vehicle, you might start thinking the worst.   One type of hissing coming from around your air conditioner may be a normal sound, or it could be a sign of serious trouble.

First - the normal sound.  When you turn off your vehicle, the refrigerant goes from its high-pressure side to the low-pressure side. Some of those noises are normal.  But when it hisses all the time, that's another story.

One cause could be that the refrigerant is leaking.  Air conditioners are fairly complex systems that involve various pumps, hoses, valves and motors.  When your air conditioner is cooling, the refrigerant changes from a gas to a liquid and back.  That refrigerant is under pressure, and there are many places it can leak from. 

A hissing sound can also be a failed valve in your air conditioner's compressor.  It is what controls the refrigerant's pressurization.  It's important to have this fixed fairly quickly after it develops a problem because when it isn't, that can lead to more extensive—and expensive—repairs.

If you hear screeching coming from your air conditioner at the same time you hear hissing, your compressor may be on its last legs. It could also be a defective clutch. 

Any time you hear a noise you haven't routinely heard before, bring your vehicle to us so a technician can check the various components and properly repair the problems.  Air conditioning systems are complex and are best handled by a professional with the right tools and equipment.  When your AC has a hissy fit, let us cool it off and you at the same time.
