Emergency vehicle lighting is used as visual warning devices. Of course, hazard lights are normally built into a car's body and for most emergencies they are enough to send warning signals to other drivers. However there are other emergency lighting devices which may be used especially when the situation calls for it. For more urgent cases, these lights may be used as they are relatively brighter and larger. These devices are often called light bars or beacons and you will find that there are certain advantages to having them.
Before rushing to an auto supply store to buy yourself some emergency lights, you have to know one thing. The use of these devices is restricted by law in most countries. You can only use them when there is a dire emergency. These lights, especially when accompanied by sirens, will alarm your fellow drivers and tell them that you need the right of way on the road. These lights can also signal other drivers to take extra caution as they approach. You will get in trouble for flashing emergency car lights when there is no actual emergency, and you will disrupt traffic and cause inconvenience to other motorists.
For actual emergencies, these warning lights will prove to be highly beneficial not just for you, but in some cases, for everyone within the vicinity as well. Emergency vehicle lighting is very useful during medical emergencies and fires, and when traffic needs to be stopped during accidents. In the United States, colors signify different situations. Red is usually used for emergency vehicles. Yellow is used for vehicles that might move slower than other cars in traffic, such as security patrol vehicles and tow trucks. Blue is usually for firefighters, EMT's, and law enforcers. Depending on the color that you see on an emergency vehicle light, you will know what to do during an emergency. You could spare yourself from a serious accident. If you do not know what the lights signify, you will still find them beneficial because it warns you that there is some kind of hazard.
If you are not permitted to use emergency vehicle lighting, you can make full use of your hazard lights when there is an emergency. Although these lights are not as bright as emergency vehicle lights, they can still help prevent accidents on the road. Retroreflectors also prove to be useful during road emergencies. They do not produce light but reflect light back towards the source.
No matter what lighting you use to signal an emergency on the road, the one thing you need to keep in mind is that you need to warn other motorists if there is potential danger nearby.
