Yes you have to get LED bulbs for both high and low beam separately.

I got mine from 4x4truckleds when I purchased the lights. Since installing them I have not had any issues at all.

Also, if your buying the lights from 4x4truckleds they sell a relocation kit that includes bigger dust covers that give you much more room to install the lights. I highly recommend these as well.

Thanks for doing this thread, will do the upgrade when I get my F150.

My Sierra is a nightmare for changing headlights.

That's what I said after I did the swap.

People tend to be overly dramatic about that. Quality bulbs don’t scatter light excessively.

Do you have a good Pic at night that shows the cutoff of headlights, like against a wall or something?

Actually I tested the "height" if you will, of the factory spread compared to these leds, low cars will only get blinded because they are BRIGHT, not because the are angled higher or throw light higher. I drove in front of y own truck and had someone flash high beams and the factor high beams shoot higher and blind you .

zero flickering, when the auto engine shut off restarts at a light when i remove my foot from the brake, it flickers once, due to power turning back on from the accessory state.

What is DRL?

i have zero flicker on my 18. I looked real hard for it and not even the faintest flicker at all. 100% sure on this.
