Autogreen blogsite: Pros and Cons of DRLs

Here is a mini article that talks about DRLs with respect to fuel costs, and European DRL issues

Here's the link:

Then, the blog's comments section battles back and forth with a few of the issues/complaints whatever:

Our input into the discussion then goes something like this (We're #12!):

"Turn signal DRLs are the answer.
1) They are proven by Australian Automotive Engineer Michael Paine to be superior to all other white light types, especially in regions closer to the equator.
2) GM's own studies have proven them most effective over all other types, and have proven them to be 3.8 times more effective than full power low beam headlights (i.e., driving with day headlights).
3) A 1998 Federal Register entry/study proved them to save up to 0.5 mpg over full day headlight DRLs (like older Volvos, where DRLs=all park lights plus low beams).
4) In 1995, Transport Canada [Canada's NHTSA equivalent] found turn signal DRLs to offer the lowest overall DRL costs for fleets [considering fuel and bulb costs], finding that they offer even lower costs than reduced energy low beam headlights, and
5) Amber light is more visible to the human eye from a physics viewpoint - it is in the dead middle of our visible human color spectrum, and amber has been noted as being conspicuous in all lighting conditions and able to be seen from the farthest distances.

Our phenominal turn signal-based product is scientifically proven to offer the best collision reduction statistically over all other types.

But we especially love #13's comment:

"I cant believe some people nickel and dime the cost of having a lightbulb on... Hairsplitting folks - get real. A head-on car collision easily costs $30,000 dollars. Why save pennies, when you can saving thousands of dollars, by avoiding an accident."

High beam headlights are the ones most dangerous (because of potential turn signal masking and glare), turn signal-based DRLs are the safest, and most energy efficient.

Article from Illinois says..."Use common sense and your lights in the fog"

This writer puts to words what a lot of us are thinking!

We are, of course, advocates of lights being "on" helps to prevent accidents, both pedestrian and vehicular. Our products help make sure you never get caught without lights on accidentally. Also our amber turn signal DRL products act as fog lights and cut through the fog "like butter". Learn more at www.BestDRLs.com.
