So, if you are really concerned about fossil fuel, I have to assume you are running with the A/C disconnected to make sure you don't turn it on when the defrosters are running, and your radio has been removed. Then again, I have to beg the question, why are you driving a Hummer...get a Honda Insight, if you are really that concerned about fossil fuel.

Now multiply those two bulbs by the millions of vehicles on the roads daily and see how much fossil fuel is involved. Its in the megawatts. It's amazing that so few people can see beyond just their own vehicle. Alternators are notoriously inefficient, too. Combine that with the inefficiency of the internal combustion engine, and you have nothing but waste.

Want to know how much it costs to run your A/C, even with the defrosters on?U.S. Department of Health and Human Services, Public Health Reports , Vol. 110 ; No. 3 ; Pg. 233; ISSN: 0033-3549 (May, 1995).
DRL costs are low, so even very modest crash reduction capabilities would be cost effective. For example, according to General Motors, there is a minimal wiring cost in converting to DRLs, and a fraction of a mile fuel penalty (about $ 3 per year for the average driver).

I love this..."according to General Motors". Don't you think GM has a marketing angle on this? GM couldn't care less if they worked or didn't work as long as it sold more cars.

As for studies:

You can quote all these studies, but so far the National Highway Traffic Safety Administration has found them to be flawed or incomplete. They have found no study of STATISTICAL SIGNIFICANCE, with controls, and of long enough duration which prove DRLs work. People said the same thing about the Center High Mounted Stop Lamp, and after they were made law, guess what? After a period of time, people were crashing into the back of each other just as much as when they didn't exist. What may sound logical doesn't always work, because we are dealing with people, not machines.

By the way, my study shows that DRLs have backfired for GM. Ever since they have been putting DRLs on their cars, their industry market share has just kept dropping and dropping. Reason: People see DRLs as a public nuisance.
