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, )

i used to leave my standard tail fog lights on until one day i let my brother
use my car and saw how blinding they are. perhaps i can try changing the
fog bulbs to the same as normal bulbs......
