Intermittent Hyperflashing in LED Switchback Bulb

[Southpaw07]

I recently swapped out the turn signals in my ‘19 TRD pro. I swapped to Lasfit LED switchbacks and everything seemed to work just fine after the install. Last night, I noticed the left side had a strange behavior.. it blinked normally for a moment then hyperflashed. I pulled aside and checked all bulbs to make sure there are no bulbs out that would effect resistance. All bulbs are working. For the rest of the drive, that bulb flashed normally with no hyperflash.
Since it did happen, I’m sure the issue didn’t just go away forever. Anybody have an idea what causes this intermittent hyperflash?

Certain Lasfit bulbs will do this when they overheat or run too long, I've found that if you stop the flashing and restart it fixes itself

This happened to me. I reworked my wire connections and moved the switchback connecting wires out a little more. Tying to make the switchback to housing connection tighter. FWIW - no more intermittent hyper flash.

Happens to mine when its really hot outside and the turn signal is on for a long time.

LASFIT even does it in cold weather. This occurs in about 1 minute’s time.

Resistors on board can’t shed heat fast enough so it bypasses and hyper flashes.

It is looking like we may need some separate, inline 5W resistors with a heat sink.

My experience too. This, even though they advertise them as "no hyperflash."

Yes, it only happened to me that one time and it was a very long traffic light. I was waiting to turn left with the blinker on. I don't like this so I may swap to a non-switchback LED bulb. Wondering if it's not a switchback bulb, if it'll do the same thing.

It happened to me too, after waiting on left turn lane for about 2 min. I have been not using the side turn signal until needed to avoid hyperflashing.

Mine is not a switchback and is the standard yellow-only bulb. Still does it.

Kinda disappointing IMO.
