They incorporate “CANBUS” resistors across the 12v lines which prevent the hyperflash, but the whole bulb gets really hot after a while, even with their best effort to heat sink the bulb. They apparently incorporate a thermal fuse which opens up the resistor path when they get too hot and they go into a hyperflash mode. I notice this with mine if I put the emergency flashers On for several minutes.

From the Lasfit website:

“Since these bulbs built-in Intelligent Temperature Control, if you use for a long time (a few vehicles maybe 2-5 minutes, it depends on year/make/model and temperature) may happen hyper flash, please turn off and cool 1-2 minutes, they will work properly again.”

3. If your setup is getting too hot you are doing something wrong. Wrong bulb for the application.
