Thinking about putting a light bar in this cutout in my bumper and wiring to the factory fog light harness. Before I actually put it in, has anybody else done this and have any idea how it affects the trans and power steering cooler? I imagine that air would still make its way around the light bar and into the coolers, but the bar is still right in front of both coolers. I just wanted some opinions on whether or not the coolers will be fine if I do this.

 

I'd imagine that you would get some restriction of air flow with that light bar. The alternative would to go with 4 separate lights spaced out evenly in that area of the bumper.

 

I ended up just putting it in there to see how it goes. I set it a little further back so the air will go into the bumper, then divert above and below the bar, rather than putting it up against the bumper and plugging the hole completely. I think it should be fine, but we’ll see how it goes. I’m going to go to a scrap yard this week and look for a headlight switch with the fog light function, and I’ll try to wire the bar to the existing fog light harness

 

Looks nice, good job!

 

If you have factory fog wiring, you will probably have to go to the stealership to activate the fog light circuit after you get the switch. I am not sure if the older platform needed to do this but I do know my 2014 gen had to have the stealership activate the circuit. Also, you can't just hook up the LED bar to one side of the fog light circuit. It will draw too much power. I know because I tried to hook up 4" amber LED cubes directly to the fog lights and it did not work. You will have to install a relay to provide enough power for the LED bar.

well I got it hooked up. The circuit DID work with only the switch, so I guess everything was already the way it needed to be. I also just wired the bar to one side, and it works so far. It’s LED, so I don’t think it draws too much power, but we’ll see how it lasts

 

Glad it is working so far for you.

Good Luck. I know that the 20" light bar draws way more power than a tiny incandescent bulb and the factory fog light wiring is about 18ga. Keep an eye out for melting wiring. Worst thing is to have your truck light up like a torch on the side of the road.

Be Safe.

I think it should help being that the bar is LED, but it probably does draw a bit more power. I’ll keep an eye out

 

Never mentioned is the brightness of the light and likely listed for off road use only.
Please pay attention to how bright and how much it is tilted downward. Yours is getting close to the same height as the head lights.
These lights mounted so high are still a problem whether high or low head lights are on or off.
Fog and driving light are in or below the bumper level for a reason and turn off when high beams are On as factory wired, by Law.
I see these kinds of lights more and more that are brighter than the head lights and are blinding to oncoming traffic.
Many are replacing driving Lamps with >>unshaded brighter Lamps<< that end up brighter than the head lights.
What does unshaded mean? ......Means the Lamp as installed with its tip forward is not covered or shaded to prevent the light from being seen as a [point source] instead of only reflected from the inside reflector housing that spreads and sometimes focused by a front housing lens or the internal reflector.
Here is an example of two Lamps that will interchange on the same connector plug. H11 and a newer 9140. The 9140 has a shaded tip for driving light use as the only difference.
Your type lights do not focus the light with any well-defined upper or side limit. like head lights that are designed do when, properly adjusted.
They are seen as a large oval blob of high intensity white light that spreads all over.
I am seeing these lights on large truck now that are 18 to 24 inches long and >>4 rows high<<.
Think what it's like even seen in separated 2 lane highways at night at that brightness level and height on a larger truck even at a distance and what is seen as on just a two-lane highway coming at you.
The owner/driver has more responsibility than just mounting Lights or making changes only for his benefit to the exclusion of others.
I hope you understand the concern being expressed and give it some attention.
Good luck.

 

In many states they're illegal whether you're got them on or not. Even if they're covered. IE New Jersey. And those lights are totally 100% useless there anyway except for looking like a clown. Summer job money just burns a hole through high school kids pocket and they just can't help but spend it on some goofy POS for their old truck. White boy curb feelers
