I got my replacement bulbs: T3-4257Rs. Installed them, tested them. Looking at the dash I saw 3 quick flash’s, then back to normal.
what have others experienced?

I'm seeing a lot of posts about replacing the factory bulbs.is there an issue I should be aware of? Ours seems fine after a year of ownership.

It’s an LED light replacement, brighter light, better visibility.

The "upgraded" Lasfits for the rears do this in my new '24 Lariat too- hyperflash a couple times then blink normally.

Yeah that is normal on the new T3 ones. It modulates until it finds the right wattage to match the computer and not trip the outage detection. This leads to some brief hyper flashing before it matches. I just got my bulbs this weekend and haven't put them in yet

No, some people just want different stuff.

I bought the Lasfit in November. Once recall done, had hyper flash.
Will Lasfit replace for free under warranty and how do I contact them?

I have done the update bulbs, and worked great for about two weeks(sometimes three quick, or just normal). Then they started hyper flashing all the time, left side worked okay but the right back didn’t work at all. Put the old ones back in and they work fine, but still hyper flashed on right side in truck, but left side is normal. We’ll see, maybe put the original ones back in??

I’m guessing lasfit.com.

The Т3 bulbs don't work properly for me.
Braking and using the turn signal causes it to hyperflash and malfunction.
Sometimes one side would just stop lighting up, and sometimes both sides.

I had the recall and experieces hyperflash. I got the T3 LEDs installed and have the monentary hyperflash along with persistant hyperflash and normal operation. All occur during my drives.

Getting fed up, I went to Forscan to turn off the tail light outage. This is what I did after the recall was done and waiting on the T3's. Really looking this time, I noticed 3 tail light related signal that were all enabled.

Outage Stop/Tail Lamp
Rear Bulb Turn Outage
Rear Stop Bulb Outage

Each of the individual outage signals stopped the hyperflash but did not hyperflash when I removed a bulb.

Disabling the Outage Stop/Tail Lamp signal seams to have cleared the persist hyperflash. With the removed bulb, hyperflash occurs as it should.

After a short drive, I only experienced the 3 click or no 3 click.

I hoped that I would not have to deal with any hyperflash with the T3's, like with the normal bulbs. I can live with this the 3 clicks if I have to.

And before someone says to put the original bulbs back in, I like the added brightness of the LEDs and hope they can help me from being rear ended.

EDIT #1: Nope this didn't work. Went out tonight and on two occasions, the hyperflash stayed on while I waited for traffic to clear.

EDIT #2: Found out today that when I have continuous hyperflash, the turn signal is NOT flashing. Happened to be turning into a strip mall parking and kept it hyperflashing while positioning in front of a store window. Putting the incandescent bulbs back in!!

Same here with the T3

Are you saying that the taillights are not lighting up? How do you know?
