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.

Have you had someone stand behind the car and physically check the lights come on? Also, are all the wattages correct?
