Led bulb help

Hey guys. I know you heard this before but I want to be sure. I installed 2018 @ 2019 Trd pro leds headlights and I’m looking to get the correct led amber signal lights to work and I have spyder tail lights also and need correct reverse led bulb. And I heard I need resistors in each tail light and that should take care of the fast flashing. Thanks for the help.

 

Pull the bulbs out and look at them. The front are most likely 3157CK (they are not a regular 3157 bulb). The stock reverse lights should be 7440. The resistors are only required for turn signal bulbs.

 

18’ and newer led housings use 7443 bulbs for the blinkers. Non ck.
