As a Top Plano Electrician, I know better than anyone how powerful and useful electricity is. It also makes me more aware of what most people tend to ignore or forget: electricity is dangerous. Electricians are required by law to carry insurance, and for good reasons. Electric current is capable of starting fires and destroying your property and equipment in a matter of moments. The proper safety precautions really can save lives, and there‘s always something we can do to improve home safety.

One of the most important precautions is located in your electrical panel: the circuit breaker. It is designed to keep you from using more electricity than the wiring or receptacle can handle at one time, what we refer to as overcurrent protection. This protects your wiring from taking on too much current, which can cause the coating around your wiring to melt, the leading cause of electrical fires. Circuit breakers serve another purpose as well; not only to protect from surges coming from outside your home, but from potential hazards within it as well. Current flowing through a failed piece of equipment or appliance can cause sparks, which have the potential to start fires or damage other electrical devices. A properly functioning circuit breaker can shut off the power to this device. It’s very important, however, that you use a circuit breaker of the proper size for the circuit to ensure that your wiring is properly protected.

Circuit breakers come in specialty varieties as well; the most important are ground fault circuit breakers (GFCI), for wet locations, and arc fault circuit breakers (AFCI). AFCI’s, in particular, can help prevent some of the most common dangerous situations in your home.

I’ve dealt with plenty of cases where electrical fires have started because people ran an extension cord under the carpet, so that they can power the lamp in the center of the room. Over time, people walking over the cord stretches out the wiring, making it so thin that the current overloads the thinly stretched wire, creating an arc fault; the electricity “jumps” the wire, completing the circuit in a way the cord can’t handle and generating heat that starts a fire. Arc fault circuit breakers prevent this by shutting the circuit down when the arc fault occurs.

So what do you need to know about arc fault circuit breakers? To start with, by code AFCI’s should be installed on any circuit that isn’t protected by a GFCI or directly wired into an appliance. It’s in your best interest to have your safety devices routinely inspected to maintain their optimum performance and capabilities; in particular, your circuit breakers should be inspected at least once a year. The inspection process is quick and relatively inexpensive, and something that simple really can save the lives of you and your family.

Let’s face it—halogen and incandescent headlight bulbs are a thing of the past. fanless, driverless LED headlight bulbs were used in this installation.

If your vehicle allows for horizontal adjustments, mark the distance between your headlight centers with two vertical lines of tape. These lines are important for projector headlights and/or lining up beam cutoff points. Repeat these tape lines for your other headlight.

6. Remove your headlight assembly if necessary, remove the current bulbs, and install your new LED bulbs. Check your owner’s manual for specific instructions on how to replace your headlight bulbs.

7. Depending on your vehicle, you may have to adjust your headlight beam before or after the assembly has been reinstalled. Your owner’s manual will explain how to adjust the beams. Align each headlight so that the top edge of the beam is at the same height as your horizontal line(s). If your headlights can be adjusted horizontally or produce two light cutoff points, use the vertical tape lines to align them properly.

3. Shake the vehicle to ensure that your suspension system is settled. For more precise adjustments, inflate all tires to their designated psi capacity and have someone sit in the driver’s seat. Also, make sure that your vehicle’s gas tank is at least half full.

4. Measure from the ground to the center of your headlight assembly where the bulb is located. This step must be done for all vehicles. If your vehicle allows for horizontal headlight adjustments in addition to vertical adjustments, it’s important that you also measure the distance between the centers of both headlight bulbs. The vehicle featured in this video allows for vertical headlight adjustments only; therefore, center lines aren’t necessary but are shown for demonstration purposes.

5. Turn on your low-beam headlights. Using painter’s tape, mark your headlight measurements on a flat wall. Measure from the ground up, and apply a horizontal line of tape to the wall; this line represents the top of your headlight beam. You can either apply one long, continuous line or small sections where the brightest areas of the headlight beams are shown.

If your vehicle allows for horizontal adjustments, mark the distance between your headlight centers with two vertical lines of tape. These lines are important for projector headlights and/or lining up beam cutoff points.
