RIP Lasfit tail lights

[gaken]

None of the above solutions for my truck. I started out buying 4 of the Amazon sourced Zonbeam brand 4257 WT21 LED rear turn signals/brake lights. These have a cooling fan, no resistor and advertise as No Hyper Flash.

All worked as advertised until they began to hyper flash 2 months later. HOWEVER, when this happened, I reinstalled the stock incandescent bulbs on the bottom left and right sides. Kept the Zonbeam bulbs on the top left and right sides. Voilà. Everything works again with no hyper flash. And no Forscan required. Evidently, there is enough electrical resistance coming from the stock bulbs, that the system cannot notice the change.

These Zonbeam bulbs have an advertised 2360 lumens of brightness with a 50,000 hour advertised lifespan (we will see about that). The top bulbs are noticeably brighter than the stock bulbs. Also are activated a fraction before the stock bulbs. I have had this set up for almost a year now.

The only side effect I notice is if the 4 way flashers are on for an extended period, the Zonbeam bulbs appear out of sequence with the stock bulbs. (Because they are activated a fraction of a second quicker). But I can live with that, because I very rarely have 4 way flashers on.

The important thing for me is to be seen, before a rear end collision occurs. As everyone knows, when these Maverick trucks have a fender bender, consider them TOTALED, due to the unibody.

I have a ‘22 Hot Pepper Red Lariat Maverick.

Nah!

It's exactly as you said, the reverse lights are the least used of all of them, with the exception of possibly the bed lights.

Well the time has come. Bought July 2023 and installed right away. Been pushing my luck since then but recently 3 out of the 4 red tail lights are dead, and I think the white back ups might be dead too. I planned ahead and got the replacements but when I swapped them looks like they are already dead. The diode dynamics aren't cheap, like $50/pair. Any one just give up and get the Form lights?

Yep, They're nice

I only cared about having brighter reverse lamps.... so I had bought the Lasfit two to three years ago. I all of a sudden was losing the right rear tail lights, Had nothing, all bulbs were out. This happed two weeks after Ford did the last safety recall software.
So I installed the original back up bulbs back. I still didn't solve the problem.
Took it to the dealer, they checked and did a point test and said everything tested good. The hooked the left tail assembly to the right and it worked. Then switched back and it all went to working. They thought maybe there was to much dielectric grease.
Two days later acting up again. Took it back to dealer and left it and the next day when they got to it they were working so they said there was not much they could do if they were not able to test unless they were out.
Three days later Hyper flash back and they were out again. Getting frustrated now.


So I ended up replacing all four rear tail light bulbs (left and right)..... seems to have taken care of the problem. The local parts stores don't seem to have them. The Napa store did have some BUT you would have to trim a little tab for them to fit. I read you need to make sure the polarity is correct and did not buy them. I ordered them from Amazon with the correct ones with the one tab. I cleared the codes, All is working now, it been a couple of weeks.
The body control module software is way to restrictive and complicated.

That's certainly an option. I just don't like the slow response of the incandescent bulbs and the safety implications of that, especially when the difference in response time is equal to a full car length or more at highway speeds.

I think this illustrates that well. LED left, stock bulbs right:

Exactly the reason I bought some Lasefits.
I had a panic stop on the highway shortly after installing them. The person behind me managed to stop almost exactly one car length behind me. That extra millisecond saved my rear end parts.

Sadly they died, the LED’s, not the driver, about a year later.

That's exactly why I have Sylvania Zevo LEDs in my taillights and not Lasfits.

No clue why anyone bothers with aftermarket tails, they are always trash.

Yeah i avoided Lasfit bulbs on my 24 after failures on my 2022 mav

- So i guess you could say i had my Last Fit about bulbs on my 22. Sticking with as delivered here as they serve the purpose

Cheers
