If you are going to have a tow truck, you want to make sure that you do everything you can to make sure that your truck is as obvious as possible when you are out and working. That keeps you safe, as well as the public in general. One way to do that is to make sure that you have plenty of lights on your truck. The lights will make sure that everyone sees you and can adjust so that they avoid you.
There are all kinds of different lights that you can have on your tow truck. You can have beacons, which are the individual lights. These are the lights like you would see unmarked police cars pull out of their cars and stick on the roof in old movies and TV shows. Then you have tow truck light bars. These are exactly what they sound like, and generally have something like LED bulbs which alternate going off and on. These are the kinds of lights that you see on first responder vehicles. In addition, you can get flashing lights that you can put around brake lights that when you turn them on will flash as well, just to give out another warning.
When you are choosing your lights, you want to make sure that you get the right color. There are specific colors that are used for particular vehicles, and you run the risk of getting a fine if you have the wrong color of lights on your truck. Red or red/blue flashing lights are generally reserved for first responders like police, fire trucks, and ambulances. They may also have to have static lights on the front or rear of the vehicle. Those static lights can also denote if you are facing the front of the emergency vehicle or the rear. For example, in most places, if you only see red lights, you are probably facing the front of the emergency vehicles. Amber lights are used for vehicles like tow trucks, snow plows, school buses, and utility company vehicles. You may also have to have white flashing lights on your vehicle.
If you are going have a tow truck you want to make sure that everyone is going to be as safe as possible. One of the ways to do that is to make sure that you have plenty of flashing lights to catch the attention of other drivers so that they can avoid you.
