Lights
A very important thing to have around the house and vehicles is enough lighting. Our garage does not have enough lighting inside or outside. My wife has been asking me for two years to do something about that because when she is going to work in the morning in the winter (and it is dark) or coming home from work in the winter (after dark) she has to use a flashlight to find her way into the house.
She has shown me a website, www.magnalight.com that sells a huge variety of lights and has asked me to consider buying a remote control light to put in the garage. That way when she needs to find her way to/from the house to/from the garage she can turn it on and off with a remote control, which would save energy costs.
So I went to the website to see what she was talking about, and I found that the website has a huge variety of lights, from 24 volt lights that I can attach to my truck, to boat lights, to rechargeable lights, to equipment lights (that I can attach to my tractor). In fact, the list is just too long to include them all!
Their website also includes a link to articles that are designed to help you pick out which light is the best one for the purpose you have in mind, and instructions on how to use various lights.
