5-pin SPDT (single pole, double throw) automotive relay.

Relays are essentially two parts in one package. The first part is an inductive coil (pins 85 and 86). This coil is the “trigger” function of the relay. By applying both a positive (+) and ground (-) to the contacts, current passes through the coil. When current passes through the coil, a magnetic field is generated and moves the switch (the arrow in the diagram). This is where the second part of the relay comes into play.

The second part of the relay is the “switch.” The switch has three interface contacts—common, normally closed, and normally open. “Normally” refers to the state of the relay not being energized.

While relays can be used for virtually any task, there are some very useful, simple applications for adding LED lighting to a vehicle. Please note that this wiring only pertains to the relay—not the wires in the vehicle. Before interfacing with a wire in a vehicle, always ensure you test the wire with a digital multimeter first to confirm circuit function.

Positive Switching

Positive switching is used for applications where the “trigger” for your switch or circuit is positive. This could be an ignition, brake, or reverse light wire for example.  This could be used for applications such as off-road light bars, work lights, additional brake lights, and other exterior lighting.

Negative Switching

Negative switching is used for applications where the “trigger” for your switch or circuit is negative. Negative triggers are often found in door, hatch, and trunk triggers as well as many interior switches. This could be used for applications such as footwell lighting, truck bed lighting, under-hood lighting, and other interior lighting.

Switch Activated With Ignition Override

This is useful for applications where you want to turn your light on or off with a switch but only want the light to remain on when the car is running or key is in the “ignition” position. The main advantage to this is—even if the switch is left on—the light (or output circuit) will shut off when the key is turned off so that the battery will not be run down.

Capitol Lighting created a friendly competition challenging local designers to create one-of-a-kind bathroom spaces and put a call out to all Northern New Jersey-area interior designers to participate. Two top designers were chosen out of numerous applicants to compete in the unique challenge of remodeling the men’s and women’s bathrooms at the company’s Paramus showroom — one of which will be crowned the “Thronedown” champion. The finalists were chosen based on previous work and have been given a $2,000 project budget with lighting supplied by Quoizel and Feiss.

Several debates continue to surround the idea of how video games affect childhood development. On one side, they have a reputation for causing violence and obesity in children, and on another, they prove to be very educational and encourage exercise. Because video games are so prominent in children’s lives, it is difficult to prevent them from playing video games entirely. However, when you truly analyze them, is it really necessary to rid children of video games completely? Research proves that while video games have their disadvantages, they also have advantages that can stimulate brain activity and help power tomorrow by assisting kids in setting and achieving their goals to reach their full potential.

Video games can be a powerful tool to help children develop certain life skills. They can help children’s brain development in several ways, including enhancing problem solving skills and creativity. They also induce quick thinking by having players solve problems to continue to a higher level, and create strategies to potentially win the game.

The most popular child development video games vary with a child’s age. For younger children, popular video games include: Wii Barbie Dreamhouse Party, Nintendo Super Mario 3D World, XBOX 360 The Lego Movie and Lego Marvel Super Heroes. For teenagers, popular video games include: XBOX 360 Transformers Fall of Cybertron, XBOX 360 Grand Theft Auto, XBOX 360 Guitar Hero II, Rock Band 2, Just Dance 2014 and FIFA 14.

Like so many other things in life, moderation is key, so monitoring a child’s video game intake is definitely important. Video games are a great form of entertainment that provide bonding time with friends and relaxation time during any afternoon. Although the negative effects of video games are very real, by allowing children to partake in developmental video games, the door is also opened for children to have a fun learning experience.

just 15 years ago. I wonder if any of the attendees at COMDEX thought to themselves “One day, I can cook my steak with the help of a tiny glowing tool that changes colors when my meat is cooked to perfection.” Probably not. Thankfully Sharper Image did, so now you can cook your steak and monitor it from your smart phone.
