As I see quite a few threads/posts about adding lights to grills (most of the time it's 3 either amber or white lights along the top of the grill) or more fog lights. Is there a limit to what we are allowed to add from a light perspective. I think I understand the no Blue/Red lights along the front, but are we getting in any form of "may not pass inspections with adding lights to the front?
I am thinking about adding one of the amber light (3 lights) to the grill some time as well as much better fog/driving lights. But really want to know whether I'm just asking to be pull over with questions.
The (3) amber lights can be considered identification lights, so that shouldn't be an issue.
Some states require auxiliary lights to be covered when on the road, but not in Texas.
Being in Texas, you can add auxiliary low beams and high beams for use on the road. They must have the appropriate approvals stamped, etched, or printed on the lens if you want to use them on the road.
You can have UP TO 4 low or high beam lamps in use on the front of your vehicle at a time. So, your low beams with your fog lights......or your low beams with a set of legal auxiliary low beams......or your high beams with a set of auxiliary legal high beams.
Having complied with the legal requirements does not mean that you will not be pulled over and questioned.
This is for TEXAS, where we both live. Other states may have other laws.
FOG lights: Sec. 547.328. FOG LAMPS PERMITTED. (a) A motor vehicle may be equipped with not more than two fog lamps.
(b) A fog lamp shall be:
(1) mounted on the front of the vehicle at a height from 12 to 30 inches; and
(2) aimed so that no part of the high-intensity portion of the beam from a lamp mounted to the left of center on a vehicle projects a beam of light at a distance of 25 feet that is higher than four inches below the level of the center of the lamp.
(c) Lighted fog lamps may be used with lower headlamp beams as specified by Section 547.333.
Low Beam Headlights: Sec. 547.330. AUXILIARY DRIVING LAMPS PERMITTED. (a) A motor vehicle may be equipped with no more than two auxiliary driving lamps.
(b) An auxiliary driving lamp shall be mounted on the front of the vehicle at a height from 16 to 42 inches.
(c) Auxiliary driving lamps may be used with headlamps as specified by Section 547.333.
High Beam Headlights: Sec. 547.329. AUXILIARY PASSING LAMPS PERMITTED. (a) A motor vehicle may be equipped with no more than two auxiliary passing lamps.
(b) An auxiliary passing lamp shall be mounted on the front of the vehicle at a height from 24 to 42 inches.
(c) An auxiliary passing lamp may be used with headlamps as specified by Section 547.333.
NOTE: the allowed auxiliary lamps must be legal lamps with the appropriate approvals.
I researched this extensively before adding mine.
I used these LED units from JW Speaker because they have low and high beam built into them. They are basically the factory Jeep round LED lights....high and low beam.
They work great, but are pricey. Hella, Truck-Lite, and JW Speaker make quality compliant lights such as these. Avoid Chinese junk if you want good lights. JW Speaker does have less expensive options available.
Something else you may like about the JW Speaker lights is that they are closer in color to an incandescent light color (5500K) than the cheap junk (6000K or higher)....so they will better match your headlights.

I have also installed the Sylvania Zevo LED replacements in my factory fog lights. They work great and illuminate much better than the stock bulbs.
If you have further questions, feel free to ask.

If you want to be legal, consider something like the Rigid fog light replacements, which are DOT certified.
Definitely no red/blue. White is a restricted color as well, except as authorized by the transportation code (headlights, fog lights, etc.) but you won't have any real issues unless you're running flashing white. Start running around with red or red/blue and you'll have a bad time.
Be careful adding additional lights. Like said before most states only allow 4 lights on at a time. So you can have 2 low beams and 2 fog lights or 2 high beams and 2 aux driving lights. With the 15+ f150s all 4 headlights are on for high beam so not other lights are legally allowed. I don't get how the new superduty trucks are legal. They have 4 low beams and 2 fog lights.

The Super Duty can do it because each side (assembly) is classified as a complete unit containing two bulbs, one complete unit on the left and one complete unit on the right. That allows them to legally run fog lights with the low beams (4 bulbs, but only 2 lights). It’s really splitting hairs, but it looks like they got away with it. It’s a similar situation with the array of LEDs you see on all the newest Acura’s, newest Volvo XC90, and the Bugatti Chiron.
While possibly open to interpretation, talking (emailing) to an automotive light expert...he felt I was safe to use aux high beams on my F150 even though the truck activates high and low for high beams. I’d have to go back and reread it to see the reason...it’s probably similar to the Super Duty. Maybe the headlight assembly is considered a single unit.
It’s the same as this one shown in these pictures. Note, the tabs for mounting the lights are forward of the bar, not behind it like some of the pics show. You just put in your truck info, though the pic shows a Dodge.
