Hyper Flash after Turn Signal Recall

[GTIgus]

I recently installed the Lasfit front turn signals in my '24 Lariat and they don't even light up. They just sit there and cause hyper flashing with mo emission of light for any function. Lasfit customer service wants me to submit a video so they can help me figure out the issue, apparently they don't know what they're doing. I've requested a refund and will go elsewhere

Add me to the the list. Just had an oil change and the turn signal recall completed today, 4/4/24. Dash indicator "hyper flashes", but the actual bulbs do NOT "hyper flash". I have all @LASFIT bulbs and have had them since I got the truck in 2022 and they have worked perfect. I have not read all 14 pages of this thread, but was a fix found or are we all SOL?

@SnyperX
Do not think about replacing them with the new @LASFIT bulbs me as well as several others have always had them burnt out. while yes the customer service will send them out for free. The product they have are junk. 4 sets for me they all burn out and overheat. I almost got into a rear end accident since all 4 gave out roughly the same time after driving for only 20 mins. My advice is to do what I did and order a nice 3 times then study flash High mount stop lamp and go to ford and get the stock bulbs ( a set of 4 cost me about 6 bucks ) while yes they are not as bright as the LEDs they work LOL. That is what I did. I am waiting until me or someone else can make a T-harness with resistors that we can plug and play and use any LEDs on them. But for now don't even bother with @LASFIT the product went down hill fast

You don't need any special harnesses or resistors, no reason to add additional complexity, components to fail, heat, etc. to the truck. Just turn off the bulb out notification in Forscan and you can use any LEDs you want, without any hyperflashing. My choice is Diode Dynamics.

The reason for resistors would be to retain the bulb out indicator

You probably wouldn't have a bulb out indicator with either Lasfit or resistors installed anyway. The resistor is fooling the computer, so unless the resistor fails, the computer is going to think your bulb is fine whether it's actually working or not.

With lasfit when they worked the out indicator was working as it should but as soon as they burnt out the indicator would let me know. It will depend on the resistor and quality

The other reports on here are that when the Lasfit bulbs have gone out there was no indication - I would say your experience is unusual.

I'm not an expert, but for a separate resistor to work that way, I think it would have to be rated the difference between the LED and what the vehicle is looking for - less resistance and it will hyperflash all the time, more resistance and the bulb out indicator will never work. I'm just not sure anyone is going to do that vs. just a high enough resistor to keep from hyper flashing.

That is what I was thinking I am assuming they also had a decoder that worked with the resistor to message the computer ?

have a lariat Hybrid all lasfit bulbs rear turn signals hyperflash on dash after recall done. replaced lasfit led bulbs with stock halogen bulbs. i decided to add different brand of led bulbs for rear turn signal bought 3157 led bulbs ifunyled brilliant red from amazon 4 ea for $9.99 and osilly 50w 60hm resistors 4pcs from amazon $7.99 cut side tabs off 3157 bulb to fit in socket. enclosed pics on install no hyper flash works just fine for my liking plus i did the jmc6000 taillight mod to the 3157 led bulbs.

It looks to me like the resistor should be wired in circuit PRIOR to led(s) and should be sized appropriately. The resistor should be of high quality and not have any drift (or less than 5-10% of the led(s) current). (A resistor can change it's resistance as it heats up). Possibly would be best that the resistor should be switched on and off with a relay when the led operates. I do not know if there is a pre start check of circuit to verify proper resistant level but suspect there is. You are correct in your observation but believe that a relay to turn off the onboard resistor when led burns out would have to be included in the led design. Perhaps a resistor with a built in silicon carbide heat sink would keep resistor in range longer?

Can anyone else who has LEDs in and had the recall done confirm this?....the truck indicates to the driver that there is a bulb out, but the actual signals flash like normal? the... "Here is the real "kicker to this whole situation. The turn signals indicators on the dash hyper blink, but NOT the actual turn signals!"

If that is the case, to me at least, I could put up with the hyperflash ticking in the truck, if the signals to everyone else is still normal pace. I would not be able to stand the hyperflashing lights to everyone else because whenever I see a driver with it (without LEDs), I assume they have no idea why its flashing quick and have no idea about how to maintain their vehicle. The ones with LEDs I assume just had no idea about canbus or load resistors and figured just put an LED in and itll work.

I am also waiting to see those who are more experienced with Forscan to see where the setting would be to remove the bulb out notification (assuming the bulbs still flash the same pace and not hyperflash). Or if there are other options in Forscan to fix this issue.

But there may be an option to tell the truck there are LED signals in...such as this post about the 2020-21 transit forums I came across.

Either way, if more people can confirm that after the turn signal recall with LEDs, if the truck actually hyperflashes the lights or just a driver indicator inside hyperflashing, along with if someone more experienced with Forscan can look into this issue more, would be great!!

+The hyper-flashing on the dash did kick in after the recall was addressed by the dealer on my '22 Lariat Hybrid, yet the exterior turn signal bulbs do still flash at the normal rate.

My Lasfit rear LEDs still occasionally hyper-flash, especially if I have the turn signal on for more than about 30 seconds. It's fine, everything's fine and they still do their job of making my intentions clear.

Do they still light up after it starts hyperflashing?
Mine stops lighting up when that happens. Safety hazard.

Mine flashes rapidly. I've swapped bulbs and Lasfit sent me another pair but it still happens at random. I've tweaked Forscan to ignore a 'bulb out' condition on the rears with no effect.
