The Michigan Vehicle Code
Appears to regard bicycles as vehicles. If so, bicycles would be covered under this legislation and would be required to run with lights on while on the road.

We can think for ourselves
How about just leaving it up to survival of the fittist.Anyone with a drivers license should be capable enough to know when to turn on there lights.Its just another reason to give the law a reason to pull you over.

Headlights are for nigthtime
Every accessory on your car uses fuel when it is operated. If you leave the lights on in your house day and night, you'll see the results in your electric bill. If you leave the lights on in your car day and night, you'll see the results at the gas pump.
It seem odd that legislators are mandating that cars get better fuel mileage, while at the same time mandating that fuel is wasted.

If daytime running lights were mandatory in the U.S. and all vehicles had them how much extra gasoline would that use each year?
For several years now Canada has required all new cars sold to have daytime running lights. Any time the car is running the headlights are on, but the taillights and other lights are off. You have to turn on these other lights from the dashboard at night. Studies seem to indicate that having the headlights on during daylight hours reduces the number of multiple vehicle accidents (although there has been some controversy about people forgetting to turn on their other lights at night -- a mistake that causes extra accidents, and a good example of the "law of unintended consequences"!).
The US has not adopted this law, but if it did they would definitely consume gasoline. Headlights require power, and a car's engine produces power using gasoline. If you make a few assumptions, it is possible to estimate how much gas the law would consume.
A typical headlight bulb uses about 55 watts; sometimes the daytime running lights run at a lower wattage so they use a little less power. Let's say the daytime running lights use 100 watts since there are two bulbs.
To calculate the energy used, we need to figure out how much time people will spend with their lights on. According the to NHTSA, vehicles in the US drove 2,560 billion miles in 1997. We need to make a guess at the average speed people drive including stops in order to figure out how much time people spent driving their cars. Let's guess 30 mph, which means each mile takes two minutes. That makes 5,120 billion minutes or 85.3 billion hours. Now if each car normally drives at night about half the time, that means that the daytime running lights would be on 42.6 billion hours a year. Multiplying by the 100 watts we get 4,260 billion watt-hours or 4.26 billion kilowatt-hours. The U.S. uses about that much electricity nationwide in 12 hours.
Now we need to figure out how much electrical energy we can get out of a gallon of gas. A gallon of gas contains about 60 kilowatt-hours of chemical energy, but this energy has to go through two conversion processes before we can use it in a light bulb. First the chemical energy must be turned into mechanical power by the engine of the car. Car engines don't do this very efficiently -- only about 25% of the chemical energy can be turned into mechanical power, and the rest is wasted as heat. After the engine gets done with our gallon of gas we have 15 kilowatt-hours left.
Now the alternator on the car has to turn the mechanical power from the engine into electrical power. The alternator does this a lot better than the engine, but it is still only about 70% efficient. In the end we get about 10.5 kilowatt-hours of electrical energy out of a gallon of gas.
To calculate how many gallons of gas this is, you can divide the 4.26 billion kilowatt hours of energy that the daytime running lights consume each year by the 10.5 kilowatt-hours of energy each gallon of gas yields. If daytime running lights were on all the vehicles in the U.S., we would burn an extra 406 million gallons of gas each year. That's only a couple gallons for each vehicle, but in total it is more than all of the vehicles in the country burn in a day. At $1.50 a gallon, that's $600 million per year. Looking at it another way, an extra 8 billion pounds of Carbon Dioxide would be added to the atmosphere by this law.
It's an interesting question because it shows how a simple idea like, "let's have everyone turn on their headlights all the time" can have a real cost when you try to implement it! Whether the benefit is worth the cost is an important question in almost any public policy decision.

Re: 2008 Senate Bill 1138 (Require headlights on all the time )
I have always thought that having headlights on all the time would be the very best thing. People now drive around in the morning or late afternoon without their light on. Just because a person can see does not mean that you can be seen by the other drivers. As we all know a lot of our side and back windows are somewhat tinted also. So this makes it hard at time to even know that you have a person driving behind you. Also, a lot of the vehicle now-a-days have lights on when you start up your car. Some of the little bit older ones just have the headlights on and no taillights which kind of defeats the purpose.
I live up here in the "snow belt" and you would be supprised to see how many people don't turn on their headlights when it is snowing. You are driving and all of a sudden there is a car right in front of you, or coming towards you. Please pass this law. Thank you.

Re: 2008 Senate Bill 1138 (Require headlights on all the time )
do we get to force POLICE CARS to keep their flashing lights on at all times too? we need to see where they are on the road as well.
they put those lights on there for a reason. why not make them use them like we have to use our headlights?
both ideas are equally silly, but, while we are being silly, we may as well be EQUALLY SILLY TO ALL PARTIES INVOLVED.
now then, silliness over.. for the time being. at least untill they come up with another silly piece of legislation.
michigan constitution, article 1. Sec. 6.
Every person has a right to keep and bear arms for the defense of himself and the state.
keep your powder dry.
