LED bulbs upgrade - smaller fuse vs resistor

hey there - been wanting to swap out my stock bulbs for LEDs, but i'm hesitant to do much wiring mods. tried to follow the directions for the resistors as best i could, but they didn't seem to work. ended up having to undo my work and reconnect the stock wires and their connections.
i was told an easier option is to just put a smaller fuse in the fuse panel. seems logical; a smaller fuse would limit the amount of voltage to the bulbs essentially doing the same thing as a resistor, but i can't find anything to back that up. i know almost nothing about electrical, and my worst fear is starting some kind of fire or screwing something up.
thoughts?
thank you!

crap - ok, so that fix was too good to be true.
thanks.. looks like i gotta do the real fix and use those resistors.
wish me luck!

What was your objective going LED? Working on one right now not the point. I do want brighter light here and there plus less heat on lenses that are OLD don't like heat anymore.
If you "add resistance" that is using up the current making heat there instead of at bulb. Required for some items to be predictable consumption for warning lights or flashers.
Other: Bought lots of 10 was cheap to find BS on the 100,000 hours life already replacing some within a few months!

hey tom - my objective of going LED might be similar to yours; longer life. i've had to change my traditional incandescent bulbs too many times, and i've also had to change my tail light assembly after backing into a pole. in addition to longer life, i'm also trying to reduce heat.
the replacement assemblies i bought on ebay fit fine, but the incandescent bulbs have melted plastic lenses the inside. doesn't look good, and i'm worried of a potential fire starting back there (unlikely, but maybe i'm just paranoid).
this saturday morning's gonna be a busy one for me! doing this resistor thing, and also gonna try installing a 12V plug setup in the truck bed... got questions on that, too, but i'll have to start a new thread for that project, unless of course that same question is in another thread.

I too used eBay to get lots of specific ones for classic to now antique cars. Dang interior lenses are impossible to find just the ivory plastic part. On to floor lighting, lights on doors, in ash trays AND in sockets of cig lighters at each door. Why? Because they are there and I wanted to.
Have replaced a few already flickered first then quit! So much for 100,000 hours? They haven't had that many hours to test them in real time I should have known.
If hard like all bulbs for a dash I'm not going there. OE ones still working.
Just for laughs have one on a 9V battery bulb #194 size lasts 4-5 months on just a plain 9V not lithium is always on with OK but used smoke detector bats.
Not thrilled with quality control the ones I've done are easy and dirt cheap. When working lumens are lots higher but so are new regular bulb usually vs old > well over 30 years lose it some :-)?
That's why I asked why for you. I didn't alter anything if I had to I wouldn't have. Also a bored spot for this WHOLE year of lockdown where I am just now opening up.
Best of all for me personally is much brighter back-up lighting it's nice long daylight now is just the opposite of course at 42+ degrees N. in latitude.
I'm still glad I did but it hasn't been a whole year yet so guess we'll see how many blow or outlive me?
