JDM Light query..., do both lights on each sluster light up? Options

[Praying_Mantis]

just got some JDM rear clusters and was thinking, some of you guys have both lights on each cluster lit up.
Do they do that as standard or do you have to alter them, if so how? thanks

(i would try them out but my car is having the kit fitted, )

Do you mean the JDM Tails? There is two red lights that light up at night and there is the turn signal. Both red lights turn on at the same time. Almost like skylines but squares.
