Daylight Running Lights only half way there.

I have noticed that most if not all the cars with DRL's don't light up the rear of the car.

A great help during some of the recent shocking weather.

Secondary moan amazing the amount of people that will not turn on lights in the rain, be safe be seen

The number of gardai driving around in their new Hyundai i40's,with no lights at the rear is ridiculous!

We've had this discussion here before.
The RSA ran a campaign a few years back to get people to keep their lights on all the time, day and night.
I think that's a good idea and so always have them on.
I only use my fog lights when it's foggy or if snow is falling as I'm not a boy racer.

I think the specific issue with DRLs is that people forget to\don't think they need to switch on their main lights when it's dark \ conditions warrant it, and this is especially risky as DRLs don't light up rear of vehicle...

Why don't they light up the rear? Is there a reason why they only light up the front?

I imagine it's to make a vehicle coming towards you more visible (that being the priority).

Makes no sense as approaching a vehicle from the back can also be dangerous on an overcast etc. day.

It wouldn't kill to have the rear lights lit as well during the day.

I like the way that some cars have an automatic lights so the car puts on the right amount...

It's down to the relative approach speeds. Two cars, one doing 60km/h, the other 50km/h approach each other from opposite directions at 110km/h, so the lights are useful in giving more advanced warning. At those same speeds, one approaching the other from behind does so at 10km/h. At that much slower relative speed, assuming eyesight is of an adequate standard, it really should be easy to spot the car in front during daylight hours without the need for lights.

Some day;ight hours can be very muggy, misty days. Rear lights on could only improve safety for all road users.

That's true, but if general visibility is reduced like that, then it's time for full lights, particularly on dual carriage ways, motorways and roads where there can be increased hazzards due to spray.

If you have your lights on you are not getting the power for nothing it uses fuel via your alternator.
Rear light should have more than 1 bulb in it, some cars like my Toyota has 3 each side, so if a bulb fails there are 2 still working

True but it's bugger all in the scheme of things. Go a bit easier with your right foot and you'll more than make it up.

A lot of the new lights are using LED's a couple of watts.

Turning up the radio for thunderstruck will use a few watts.

Be seen use the tiny extra drop of fuel.

Always drive with front and back lights on, even in the middle of summer.. Keeps my mind at ease!

That tiny drop of fuel x millions of cars

Using that logic we should all stop using our radio or, heaven forbid, our CD players. As for accelerating and driving fast (within the speed limit)...

Thank you purple.

Save a drop of fuel or be visible and save lives.
Roker you need to look at your priorities.

If they are that worried about fuel don't drive in the dark or rain maybe don't drive at all.
