Hi guys, my tail lights are not turning off on my 1996 ls400.

Ive had to recharge the battery once already and have had to take the battery off overnight.

Any quick fixes?

Thanks

check the wire harness on the trunk hinge which powers the lights on the trunk lid. they tend to get brittle and start shorting out each other after years of open/close of the trunk. this is more common on 90-94 models but can also happen on newer cars.

has that really happened on 96 and newer? - I thought there was a design change fix in 95?

I would start with the obvious, check the brake light switch, if it's ok, then get the real factory wiring diagram and it should be simple enough to trace down the fault!

this 1995 factory wiring diagram is cheap and will do just fine in a pinch, practically no difference from the very hard to find 1996 edition

when i was working on the trunk area, i did see the harness rubbing against the insides of my 97. i did NOT see any breaks or tears on the loom of the 150k miles so this point could be mute.

i second checking the brake switch! it's located above the pedal.

Thanks everyone.

It was a small rubber switch apparently, only cost USD3 LOL.
