Question:
On the STL3RB and STL2RB I dont see in the description for running lights. Also are your tail lights compatible in using both function running lights and turn signals at the same time. 2015 Toyota Tacoma pickup. has a standard 7 prong adapter.

Hey Benny! The side marker light is the same as a running light on the # STL3RB and # STL2RB. They are powered by the running light circuit and you can see them illuminated on the side of the light in the picture below. I also attached a review video. If you take a look starting at the 2 minute mark you will see that the side marker light remains illuminated while the turn signal is flashing. If you have any other questions feel free to reach out in the comments below.
