Hyper flash issue.

I've got a 2017 and decided to change the rear turn signal lights to LED. Bought some, installed them and no issue...until now. I've realized that when my headlights are on the LEDs hyper flash, but when the headlights are off they don't. I don't have LEDs anywhere else on the exterior except for the backup lights. I also don't have any load resistors installed since these LEDs weren't supposed to need them. Guess that wasn't true. Any trick to resolving this issue since it doesn't hyper flash all the time or should I just change them back?

 

I believe the answer is 9 ohm resistors but not positive. The answer is in this thread though https://www.tacomaworld.com/threads/tail-light-mod-both-lights-used-as-brake-and-signals.471450/

 

Add some resistors.
