I've done many lighting mods to the MR2 to improve the night look, as well as to improve efficiency as LEDs produce much more llight with less current as there is very little thermal waste compared to halogen globes. The basic mods include switching all interior and exterior lights to LEDs. This basically involved finding the globe socket type, and replacing with a matching LED. I did my best to colour match using a consistent temperature value for a similar white. The pop-up headlights, reverse lights and side markers were changed to LEDs by the previous owner. The basic swap I performed includes:
The larger and more interesting light projects I undertook were:
The MR2 kouki lights have two left-right pairs of red lights. The inner was for braking and the outer was for taillights.
To modernise the car, I decided to add Daytime Running Lights (DRLs) wth switchback LEDs.
