[AT] tractor hauler a pain to install headlights.

Sun Jan 19 19:10:51 PST 2020

Mine runs the headlight current through a diode before it gets to the bulbs for daytime running lights, and cuts out the diode for regular headlights. I had to replace the diode once, it was under the dash. It only drops a few volts.Brian

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.

Yes 
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.

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.

I 
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.

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". 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. I am guessing now that the insurance explanation says it all. 
I thought for sure that EPA had something to do with it. I guess I am just 
getting too old, I am one of those people that just don't matter anymore.

  ????  I don't 
  think a dangerous situation like that can be industrywide.  My Ford 
  Escape turns on both front and rear in the auto mode.

    While we are talking about 
    vehicle lights, please, someone explain to me why or how anyone would want 
    to have lights on the front of their vehicle with no lights on the rear. It 
    appears that this condition is industrywide and seems to be always in the 
    "AUTO" mode on the headlight switch.
