1997 Ls400 Rear Light Failure Warning Light


Recommended Posts

Recently my '97 LS400 started displaying the "Rear Light Failure Warning Light".

After checking EVERY bulb & insuring there were no burnt bulbs the light still displays continueously.

One obvious difference that I've noticed is that everytime when I first start the car up, no problem. But as soon as I press the brake pedal and shift from PARK to REVERSE, the light displays.

Can anyone shed some light? (No pun intended)

Thanks from Houston, Texas!

I think the system can only check the brake circuit once you press the brake pedal so not seeing the warning light when first starting up makes sense.

I would recommend removing the bulbs and clean the terminals and check for corrosion in the bulb holder.
