So these is some kind of packaging standard that all of these fit. Kind of like 2032 or 2025 cell batteries fit a package design.
Well, it is a thought.
I am getting ready in the new year to replace all lights in my car, From those behind the panels to illuminate the heat knob, dash lights, panel, backup, brakes, turn signal and headlights. I want to blind other people for once. A person can barely see at night with newer cars coming at you with the LED and whatever else they have. Mostly, I just want the dash and interior to light up brightly, improve the headlights, and the backups..but may as well do them all. This car will be my last, I am sure.
