yeah i actually have them in my car
heres a mini-DIY if you want to do it
1. take out cupholder
2. drill 2 small holes (depending if youre using a 3mm/5mm LED) in the side (holes should be visible to driver)
3. take out the shifter console light wire and splice it
4. take 2 LEDs and hook them up like so:
(+) existing shifter wire -> 420 ohm (or whatever ohm resistor) -> LED
(-) existing shifter wire -> LED
take an LED holder and put it over the LED and put it into the shifter console tightly so that the wires are on the side neatly (you might want to even put electrical tape over it)
superglue it in place and tada youre done.
one of my LEDs are blown, but the other one works and its pretty cute
btw for the wiring try to use as thin gauge wire as you can like 22 gauge
