I drive at night over 100 miles daily.

Halogens suck enough, but i do want to know if theres a mod to keep the lows and fogs on when i switch to HI BEAMS....

ANYONE??

I agree with the OP in wanting more light. I do not have factory "driving lights" (hard to call them"fog lights" since they are white not yellow) but I have no problem with wanting to use both driving lights and high beams at the same time especially in rural areas like where I live in Tennessee where there are no streetlights and a lot of miles of dark and dangerous roads. Of course I would not use anything more than low beams when there is oncoming traffic, but lighting up the night when there is not oncoming traffic is a great thing in my mind. When I install a set of driving lights on my car, (likely 6000k HIDs they will be wired to work with both high beams and low beams as I decide...) I will also aim and adjust them properly too and I hope to do a true HID/Projector conversion to my Cruze soon too, just saving the money now...

With older 4 headlight systems like on many GM trucks that shut off the low beams when the high beams are activated there are kits to wire in and trigger all 4 lights to be on and they work great to put more light on the road. I have had them on previous vehicles as well as my current Tahoe and will be wiring my Silverado for this operation as well. I do not drive with high beams when there is oncoming traffic so they work fine and to provide extra light without disturbing others...

I would venture to guess that most of the posters that are citing laws and whining about running "fog lights" with high beams live in city areas where there are plenty of street lights as well as much traffic and high beams are rarely used, in rural areas more light is better and desired!!!

I have been reading this and can confirm that high beam and fogs together on a country trip are really useful. High and low at the same time would not help if the fogs stay on as well. In the Holden Cruze the fogs do stay on with high beam and they fill in the gap nicely and also light up the sides of the road. I would suggest that you research how the Holden is wired if you really want this, as it is like that from the factory.

I did this mod on my '15 Silverado, love it. The lows stay on with the highs. It was a simple mod, just added a diode between hi-beam pin and fog light pin on the BCM. There are some other mods that I have done on my Silverado that I would like to do on my Cruze.

- Fog/Driving lights on with HIGHs
- RED LED bulbs in all brake lights
- Black bowties, all the way around
- White LED lights inside, including trunk
- LED light stripe(s) under the hood

Saw another mod, somewhere, they turned the trunk lid lights into brake lights, as well as tail lights. Another mod was turning those same ones into turn signals, too.

Fog lights illuminate an area that is just a few feet in front and mostly to the side of your car. They are useful at VERY low speeds only. At normal highway speeds you really should have minimal light immediately in front of the car and wide dispersed light far in front so you can see deer etc. Having a lot of light right in front of your car actually tends to make you focus where the light is brightest (right in front of your car) instead of hundreds of feet down the road like you want to be looking at speed.

One other thing that personally helps me a lot at night is to turn the dash lights almost all the way down. Again, I don't want my eyes flooded with light from inside the car when I'm trying to see what is outside and in the dark.

I have to disagree about the fogs being on with high beam, as I did a 10 hour interstate drive at night with them on and it was fantastic being able to see animal eyes glowing on the side. It must depend on the individual how it affects the driver. Remember I have it available standard on my Cruze and have used it, that doesn't mean it is suitable for everyone.

I only agree with the interior lights be on as low as they will go at night. Mine are always at low interior lights, I never increase them. I have also adjusted the "auto-lighting" to be sensitive enough for the interiors to come on when the sun comes up. This is all on my Silverado. The Cruze is actually my daughter's car.

I actually prefer high and low vs the high and fogs. Luckily my current car I can run high and lows. Some places I have street lights that flood 1 major area and then goes pitch black shortly after not giving you much time to readjust your eyes. On the way to work I literally almost hit 2 deer from one of these transition spots. Most of my job area is "Back Woods" to the point the moon would hit the chrome window trim on the drives door and into my eye causing me to lose some of my night visibility. I see where the OP and others are coming from, most the folks with these concerns just tossed on one (or more)of those fancy LED lightbars and pressed on after the headlight harness modification wasn't enough for their liking.

As for interior lights you can press infotainment and say "Screen off" or Display off" and kill the MyLink screen at night w/o going into 4 menus to achieve the same thing. The thing that got on my nerves is the Hi Beam, T/C, and park indicator lights are still full bright no matter how much you dim the instrument cluster and center console.

I would think you could do it like we in the GM truck world used to with a couple diodes between relays. Best bet is to get a wiring diagram and start figuring out which relay pin is a trigger for the low beams and tie into that for the highs and fogs.

How old were those trucks and were they wired to the point that the BCM controlled pretty much everything?

I've done some of the diode/BCM modes to my '15 Silverado. I've been looking for the BCM and a schematic for it, so I can do some of the same mods to my (daughter's) Cruze. Eventually, will do some of the same mods to my wife's CR-V.

Merc6, it depends. The all-on mod has been done to all generations of the trucks since 01. I would imagine the Cruze's electrical architecture to be similar to the 11-16 trucks, but Id have to do some research into that to be sure.

High and low beams isn't possible with stock cruze headlights as it's all in one bulb. You must have aftermarket lights with separate high and low beams to do this. Highs and fogs is possible however, and just requires a diode to go from the high beam wire to fog light wire, and I've done this mod and it immediately blows the high beam fuse since it's too much amperage all at one time for the fuse/wiring to handle. And people saying it's not useful are allowed to have an opinion, but in my experience it would be useful since fogs add side visibility that you lose when engaging the high beams. They aren't nearly bright enough to flood the foreground and "hurt" your distance vision, but they are bright enough to light up ditches on either front side of the car. And yes, it's technically illegal, but considering high beams are only on when you are not approaching traffic, that really doesn't matter.

As the Holden Cruze fogs do stay on with a beam change there must be a simple solution. Would a relay solve the problem?

By the way headlights are H4 globes and fogs H8.

Possibly easy, but more than likely not. It?s probably BCM controlled rather than relay controlled.

Saw another one of the m*r*ns this morning. Pickup truck, four headlights and two driving lights tie wrapped to the grille on the highway that has overhead lighting every 100 ft. I hope he could see better than I could when I saw him....

Don't think that he did the mod correctly. Regardless, he should have still lowered his lights to low beams, if the mod was done correctly. Personally, I would have fired my highs back at him, until he dropped his.

Seen 'em agin this mornin'

Could not do that as too many oncoming cars, I'd have been just as guilty.

I found this thread here today:

http://www.cruzetalk.com/forum/25-gen1-service-issues/147969-high-beam-relay.html

Looks like its not as readily possible as I thought. Would be very difficult to tie the high beam relay to the fogs unless you knew electronics very well.

Best bet is stand alone LED bar.
