Before you do that, see what voltage you have across the bulbs?
If you have battery voltage (whatever that is on the day) less about half a volt, then you'll gain very little. But if you find you have far less than battery voltage across the bulbs, well worth doing.

I've checked and said on here somewhere before now,there was about 10.5 volts at the headlight plugs

i never checked mine but after the 3rd headlight stalk i fitted last summer id had enough...
too much load passing thru it, massey in there wisdom fitted a relay on the full beam circuit to fix this but forgot about the dipped beam where there is only just slightly less
current passing thru the complete switch contacts.... so i added in a relay on that also & at the same time ran 16amp Positive & Negative rated feed directly from the battery right
to the lights upfront eliminating all of the previous issues (I HOPE)
all working fine since.
Not much brighter but the better bulbs helped.
I see on the demo 6718S i had a few weeks ago that headlight multi function switch doesnt latch between main & dipped beam now.
so at first is a bit confusing, also the indicators finally self cancel (Progress)

the contacts will melt eventually depending on how long your lights are on for trust me.
The quality of that part isn't that good, not to run full current through anyways.

I can’t find them in my purchase history, must be over 3yo. Easy fix as they are standard main/dip bulbs, just a lot of choices.

i tried LED bulbs in mine but the led bulb was too long to fit in

I wanted to change the whole lot, because the glass is cloudy, but couldn't be sure of buying something that would fit.

I’ve got some square ones that dip on one tractor they work spot on
Cab lights are round on a 7480 I think that’s what @Will Blackburn is getting at
