scrambler how do i shut off the automatic headlights that come on everytime i start the car. they come on in the daytime and i have to manually turn the lever to shut it off everytime, but it comes back on when i start the car again. i dont want the headlights on in the daytime.

You can't permanently disable it. DRLs are a saftey thing, and GM actually kinda pioneered their use in the US...so you have to manually make a choice to make yourself less safe as turning off the Automatic headlights also disables the DRLs.

Enjoy your new (to you) Spark man!

And yes, it does improve people seeing our little cars. As for the DRLs...the watts they pull are so minuscule I doubt you could even measure their effect on range.

Agreed, the amount of electricity used by these lights is marginal compared to the battery size and the electricity used to move the car.

Don't overthink the range thing too much, and enjoy the car :)

The low-beam front headlights draw 55 watts each for a total of 110 watts. It would take about 9 hours of driving to consume 1 kWh - about 5 miles of range.

There's also DC-DC conversion loss. I guess about 10% for close to 130 W.

I get 5.3 mi/kWh on average after 16K miles, 4.4 mi/kWh at 70 MPH. Then DRL would be like driving about 0.6 MPH faster than your indicated speed. Due to rounding error, it might be like driving 1 MPH higher than indicated.

If you drive in Los Angeles (massive traffic, 24/7) and getting over 6 mi/kWh, DRL would be like driving 0.8 MPH faster, again rounded to 1 MPH higher. 15 MPH would consume energy like 16 MPH.

But if you have lead foot and only getting 2.5 mi/kWh, it'd be like driving 0.3 MPH faster than indicated. It's even less worth worrying about with lead foot.

In other words, it's better to slow down by 1 MPH from your normal speed than turning off DRL.
