Grill light mod 21 Pro4x

After not wanting to take apart the grill to install the OEM grill lights. I modded aftermarket grill lights for a Tacoma into my 21 Titan Pro4x. I modded the harness to use 3 out 4 lights and 3m tape to afix them into the grill. For now I have them wire tapped to the passenger headlight wiring. So lights turn on when Titan starts. Maybe I’ll control them with a separate switch & harness later. Enjoy.

That looks great! Can you post a link to the lights that you bought?

I used a similar kit to this one from Amazon. They are all basically the same.

Are these just a decorative light? I have them on my '23 XD Pro.

Sure any aftermarket light can be considered decorative. I installed them for added visual safety when driving.

This maybe a dumb question..but can you show how you tapped the lights into the headlight? I want to add some lights and I am trying to figure out how to do it.

Not at all. I drew power from the passenger headlight adjuster harness. I used quick splice taps; black to black/red to red. Just in case, I also added 5amp inline fuse to the harness. Its a little tight but can be done. Lights up when truck is powered. Hope this helps you out.

How did you install the lights without removing the grille?

It was tedious. Manual dexterity is involved. After deciding which slot on the grill I was going for. I applied and trimmed 3M tape on the top of each lens. Making sure to clean surface well with alcohol. I then slid the light behind the grill. Angle the light down and push up into position. The light is then sandwiched by 3M tape and lower grill vanes. Do this for each light first. For the main harness, there is a rubber grill shroud on both sides you can route the harness through to the engine bay. I passed the harness from one of the large grill opening front side of grill using a long zip tie. Once main harness is behind the grill; connect each light. Its good to have a pair of extra long needle pliers to help maneuver harness behind the grill. Hope this helps.

So from what I've been reading is that any truck 80" or wider require them. So my stock 2019 Pro4x is 79.5" so if I even think of adding wider tires or wheel spacers, I'm supposed to get them. Well I'm sure no one is ever going to pull me over and measure my truck.

2​
Front Clearance Lamps-
Attention: Required for vehicles 2032mm wide or wider		( P2, PC* or P3*,PC2)
*photometrically certified at installation angle		Show vehicle's width
Minimum 2​
Yellow​
At widest point - symmetrical - on the front or near the front - facing forward
As high as practicable​
3​
Front Identification Lamps (ID) (P2 or P3)Indicate presence of a wide vehicle
Exactly 3​
Yellow​
on the front - center - horizontally spaced 150 mm (6 in.) to 300 mm (12 in.) apart
As high as practicable or on top of cab​

If I'm reading this right, and if you're familiar with "chicken lights" (lights on cabs of big trucks) on those the outer two lights are required to show the width of the vehicle to oncoming traffic, while the inner 3 are there to "indicate a wide vehicle". I read somewhere that Manufacturers are interpreting "as high as practicable" as being on the grill, not the roof.

All that being said, they look cool and I'm reading this thread because I plan on doing this to mine. I've already sent back one set of lights because i couldn't come up with a good way to mount them, but I may try what Darr did. I saw the round ones someone did here that pop in but I didn't really like that look.

SO, I'm probably about to order these and try it out.

I think that for you guys with XD's it's a factory option. I don't think it ever was for the non XDs. I wonder if it's automatic upgrade if you do anything to cross that 80" boundary.

Yup, I have read articles concerning the lighting topic years ago when the Raptors started appearing with the grill/auxiliary lights. I use to follow F150 Forums. Even installed them on my old Expedition and F150. I tried the round ones, but didn’t look clean enough for me. I prefer a recessed mounting. Besides the lights looking cool. They do serve a purpose.

The lights look great, If I install them they will be on a separate switch, I will not tap any current wires and they always end up going bad whether it’s corrosion or other failure.

Taking the grille off SUCKS. I also have lights to install which I am going to do the same as the OP... some type of strong velcro or tape. They were only designed for the XD and that was not made clear when I bought them. Anyone who says they fit on the Pro 4x with no mods is full of it.

Yup - thats why I installed them that way. I read the instructions for the OEM grill lights and said no way. Use 3M automotive tape and you should be good to go. Make sure you clean the surface well.
