Okay so apparently the lowered voltage for the daytime running lights on a Chevy Cruze is now controlled by the BCM and it no longer has a separate relay that can just be pulled to disable daytime running lights. Does anyone know what the lower voltage is for daytime running lights? Or I know of a way to disable daytime running lights. Reason for asking is wanting to upgrade headlight bulbs.
You have a voltmeter? Should be easy to check at the socket.

I do but litterly all tools are in my storage unit which is a 40 minute drive from me .So trying to make a plan of attack without having to spend that time.
got a Horrible Freight closer than the storage unit?
In reply to AngryCorvair :
Yes that's about 25 minutes
If it's controlled by the BCM, it might be pulse width modulated.
My new Crosstrek has the same low voltage high beam DRLs, and I hate them. The forums all say the older models have a relay to pop out, but the new 18 & 19s are different. First oil change I'm telling the service dept to disable them with their computer.
In reply to Dr. Hess :
Isn't that really hard on filament bulbs? That would explain why I lose bulbs in my Volt about five times a year to be honest. I hadn't even thought of that.
In reply to Jerry :
If it was my high beams I wouldn't care at all. I can deal with having regular all halogens in my high beams it's my low beams. If it is under 9 volts by significant margin then I don't care either the bulbs just won't fire at all no big deal. But if it's anywhere close worm a spike I don't want to underdrive my bulbs and have them flickering and just wearing out.
In reply to Jerry :
Good luck I'm hopeful maybe the dealer will do that for me but I highly doubt they will
Are DRLs now law in the US? I am sure that in the past they were not even though they were offered on many cars as standard. I think the reason they were offered is they were law in Canada and the manufacturers just build one N.America spec.
Now, with seeing all the newest cars running LED style light strips in the front for DLR, I wonder if they are US law also. If they are, your dealer is not going to disable them.
In my old Volvo 850 wagon, it was optional to have DLRs via an adjustement at the headlight switch. For the Volvos, a turn of the screw driver at the switch either gave you DLR or not.

I wish. So many idiots in their asphalt colored cars running around in the rain with no lights on.
In reply to Grtechguy :
Yeah, but is it law that cars now have to be manufactured with the feature? This does not mean that the driver of a 2008 grey sedan will be required to turn on his lights.
In reply to John Welsh :
It is not yet.

That's actually a state law here and several other places that no one follows or enforces, if your wipers are on, your headlights should be on. Of course I see a lot of people driving around in the rain without wipers either. As far as Federal with the DRL? I thought they became mandatory for new vehicles in the last 10 years, but I could be mistaken as I don't shop new vehicles.
DRLs are not required in the US.
[A petition was] filed in 2001 by General Motors, seeking to have NHTSA mandate DRLs on all U.S. vehicles. The GM petition was denied by NHTSA in 2009, on grounds of severe methodological and analytical flaws in the studies and data provided by GM as evidence for a safety benefit to DRLs. In denying the petition, NHTSA said
(…) the agency remains neutral with respect to a policy regarding the inclusion of DRLs in vehicles (…) we do not find data that provides a definitive safety benefit that justifies Federal regulation (…) manufacturers should continue to make individual decisions regarding DRLs in their vehicles.

it's encouraging to see a government agency say "we're staying out of it"
Does your insurance give you a discount for cars with DRLs?
Why do you want to disable them?
In reply to T.J. :
re-read katyb's posts, she clearly states a good reason to disable them in her circumstance.
In reply to TurnerX19 :
I did read it, but failed to ask a clear question. I guess what I am asking is what does one have to do with the other? How does upgrading headlights require DRLs to be disabled? I am unaware of the interlock because I have never tried to upgrade the headlights on a DRL vehicle.
Incandescent bulbs won't flicker if you PWM them fast enough. LEDs will, and something like an HID will probably just break after a short time. If you're replacing with something other than incandescent, it's a problem. If you're replacing with high dollar incandescent and feel that it shortens the lifespan of your expensive bulbs, that may also be a justification.
I will be upgrading to either led or hid. Probably led based on the amount of times my headlights turn on and off a night(35 to 45 times is not uncommon)
If worst comes to worst I'll install a voltage switch on each line that will shut off below say 10.5 Volts but don't want to install unnecessary things if I can avoid it
Are the DRLs and headlights using the same bulb?
In reply to 914Driver :
Yes. Drl is on the lowest bulb (car is the low model ls so does not have the projector housing with led drl. Just regular 4 beam setup)
