7443 led switchback -- do they hyperblink?
 

I want to get 7443 switchback LED .. but does this cause a hyperblink?

Unless you get a resistor or new flasher box yes it will.

yes.

When you upgrade to LEDs for the turn signal lights, you will need to upgrade the flasher unit under the driver's side dashboard or add in-line resistors to address the hyperblink issue. The flasher unit is the way to go, given that it's a simple upgrade and it will also allow you to revert back to OEM if you had to in the future. The flasher unit upgrade is plug and play and all you have to do is to remove the old flasher unit and install the new flasher unit.

Our newest flasher unit also has a blinking speed adjustment feature to allow you to fine tune the speed of your turn signal LEDs (added bonus).

Feel free to contact us if you have any questions. :D
