This is my snow vehicle in case anyone was wondering. 1989 Toyota TownAce Turbo Diesel 5sp 4wd. It's right hand drive, JDM model. Getting custom steel bumpers built for it soon front and rear.
Engine off, key in pocket, any rear door open: Push the turn signal switch forward then back. Hear one chirp. This tuns off the outside lights until the next time the car has been locked. The dome lights will still stay on for ten minutes after each time a front door has been closed and opened.
