Anyone added any extra interior lighting?

just wondering what some of you may have done to help light your interior.
What lights did you use and where did you place them.
I just ordered an led bulb for the dome light, but was thinking of adding lights under the dash on each side, or maybe lights on the sides of the console.
What have you done?
I have in the past. Simple splice in’s to add floor lighting. Friends of my me did the same but use plastic beer signs as the light cover.

It’s ether splice in near the light or splice in at the switch.
