I am currently replacing all of my light bulbs to LED on my 2019 F150.

So far I replaced my license plate lights (168/194/2825) ,
outside dome lights, middle break lights (921/912),
my reverse light (7443).

I will replace my headlights with LED (I think they are H11), if I'm wrong please correct me.
What are the LED number for the fog lights??

I want to replace my brake lights, running lights and turn signals. I hear that when you replace with LED the turn signals flash fast.. I do not want to add resistors (trying to reduce amps within the wires) the older f150s had a flasher that you can replace with a more heavy dudy flasher.. Is there a way to replace the flasher in the newer F150s? I noticed that that I can't hear the flasher clicking anywhere but it is piped in thru some speakers in the truck. Are the turn signals computer controlled?

Also has anyone added amber strobe lights (caution lights/strobes) to their F150 near or in the reverse light area and or near the front turn signal area? (For work I do alot of stopping and getting out of vehicle on or near busy roads).

 

I have a 2018 and upgraded my driving lights with a total unit (I've included the link).
Much better light pattern than a bulb replacement.

My 2018 has H11 for low beam and 9005 for both high beam and driving lights. You can look yours up at any auto parts store website.

As for strobe lights, they have self contained lights you can wire to a switch or tap into your turn signals. Strobe circuit is built in. They are used frequently on escorted and construction vehicles. Shop around as the same part can have a significant price difference from each supplier.
I recommend starting at Iowa80.com in their safety and compliance tab and expanding your search from there.

Side note: they also have LED turn signal bulbs with built in hyperflash resistor.....plug and play. You can websearch and find those same bulbs for around $18/pair. (Iowa80.com is a little pricey but a good starting point).
