LED reverse bulbs

[SupremeWill]

Can somebody please point me in the right direction for getting LED reverse bulbs that will work. I've tried two different options for Amazon but the ends seem to be too small and won't fit in the tail light connectors.

For my cab reverse, I used these:

For the cap brake center bulb I used:

I'm looking for the tail light reverse bulbs, these are the exact ones I bought and they are too small.
But they do work great on the cab

I think the manual has some misprints. I bought some 3157's for the rear turn signals and they were too big.

Finally figured out the reverse and brake light bulbs are w21w bulb

Which ones did you get? No error messages?

diodedyanamics are the best I've found. Just put your truck model in and it list all LED's available. They ain't the cheapest though.

So is a resistor just needed for the turn signal but not for brake or reverse bulbs?

Just to update:
I replaced my brake/tail with these - 7443 size - No dash error since install 2 weeks ago : https://www.amazon.com/gp/product/B077PR5B8G/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

I replaced reverse with these - 7440 size - Not much brighter than factory halogen in my opinion : https://www.amazon.com/gp/product/B07414XVK/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1

I also am using those reverse bulbs without issue.

I had ordered those brake/tail lights as well and couldn't get the bulb to fit/connect snugly in the receiver.
Did you need to modify anything to get it to fit?

Nope. Direct replacement and popped into the socket and twisted right into the lamp housing.

Nope. Direct replacement and popped right in.

Got it thanks man

I installed the same reverse lights last week. Not very impressed. Gonna look for something brighter.
