<div>The last car I had where I actually knew how it was wired was a ‘96
Cavalier. It used a relay for the DRLs that put the two headlights in
series, giving them 6 volts each. It may have used the hi-beams, don’t
remember. In any case, there was a huge difference between the DRLs and
the headlights on full power. Again, as you say other cars may be
different. I’m unaware of an actual requirement for DRLs, so there may be
no standard for brightness.</div>

it is 80%. There is very little increase in brightness when I turn the
light switch on. Maybe its different on today’s cars, mine is 21 years
old. My DRL’s are not separate light bulbs, they are the actual
headlights.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="FONT-FAMILY: "Calibri","sans-serif"; COLOR: black">Yeah, what Brian said
about DRLs, except maybe not at 80%. Automatic lights respond to light
levels and should turn on both front and rear. Most if not all also have
an instrument panel indicator so the driver can tell if the automatic lights are
on. They do not know when it is raining as light levels in rain are
usually above the level that turns on the lights. It is still up to the
driver to turn on lights in the rain.<o:p></o:p></span></p></div>

don’t know how all the auto mode lights work, but my ‘99 Chevy Tahoe has daytime
running lights and no auto mode. Daytime running lights are the front
headlights only and are always on at 80% brightness whenever the engine is
running and the parking brake is not set. I don’t consider these auto mode
lights. If I want my rear lights on and the headlights up to full
brightness when it is getting dark or when it is raining, I have to turn my
lights on manually. Daytime running lights are to make oncoming traffic
more visible in shaded areas.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="FONT-FAMILY: "Helvetica","sans-serif"; COLOR: #333333">Howard, I am glad
to hear that on your escape. The last four vehicles I have had would not turn on
the rear lights when the auto mode turned on the front lights. One of those
vehicles was a pickup truck. Now I am wondering what condition turns the lights
on in auto mode. Several years ago my wife was driving in a rainstorm while I
was behind her. When we stopped I raised the roof because she had no lights on.
She advised me real quick "I had them on auto mode". <br>The next time you are
out in the daylight take a look at the oncoming traffic and see how many have
lights on the front but none on the rear, unless of course they are applying
their brakes. <br>I am guessing now that the insurance explanation says it all.
I thought for sure that EPA had something to do with it. <br>I guess I am just
getting too old, I am one of those people that just don't matter anymore.
