I know this has been discussed in a lot of threads but wanted to get ideas for the upfitters. I am planning to go with one of the amber lights to fit in the front grill and maybe pillar lights but would love some other fun ideas. They don’t necessarily have to be super useful and I don’t think I want a horn or an on board air compressor.
Would love to hear anyone’s ideas or what they’ve done. Might also consider some rear backup lights but seems like those would just tie into the taillights anyway. Can be useful or just fun!
 
First thing....add the wire harness to the engine bay from CBlightingdesigns - that will make your life much easier when adding your accessories. Those upfitter wires are incredibly short.
I just dropped an install video. For me, I would like to add an ejector seat, oil slick, smoke screen, Invisibility cloak, Afterburner and maybe a nice massage function for the seat..

In all seriousness, I am going to add the Spartan MKII pillar lights from F150LEDs, they have an aux light and then full blast mode. Probably the side vent lights so they are not running all the time, and maybe the hood light from sickdiesel.

Being able to return to stockform quickly is a great idea rather than having every accessory light tapping into the DRL/ running lights.


 
Thanks, and actually watched the video early today and already ordered the harness! I like those pillar lights and the vent lights too. Thinking those and maybe the grill light are a great start until I can find some good solutions for your first suggestions 😂
 
I am adding an Anderson power pole in the bed for 12 volts. It will entail larger wire and another relay under the hood that connects directly to the battery. One uplifter switch will control the relay. The wires from the uplifters are around 16 so wire leagnth and size is paramount so beware of voltage drops if wire gets too long. Voltage drops/amps go up. 16 gauge with 11.5’ at 5 amps will effect voltage by 2%.
