I've got a 95 sc300. The lamp failure light on the dash is still on. I've changed the parking lights and even the license plate lights. All the lights seem to work but I the lamp failure light still is on. Are there any other lights that could trigger this? Thanks.

 

have you check the 3rd brake light and the other 3 brake lights?

 

yea, my guess is check that 3rd brake light in the back (inside the cover that goes on top of the subwoofer). I believe there are 2 bulbs in there? Eitherway, if that light is off, then you will get the dash indicator. The License plate lights are not connected to that sensor as I've had mine blown for quite a while without the sensor indicator. Check your reverse lights as well!

 

the license lights ARE connected to that sensor.
my indicator was on, and when i replaced the license light that was out, it fixed the problem.

 

my 94 SC the license plate white bulbs in the back are NOT connected to that in dash light. My light is on always because of my aftermarket spoiler not drawing enough current to kill the light. I can plug my regular 3rd brake light in and the dash light goes away, yet my license plate bulbs have been out for YEARS

 

well...i just noticed that the light still comes on now and then...it maybe that i have some sort of short in the sensor or with the wires somewhere...the rear lighting array works fine, all the time, but the sensor still comes on everynow and then...remo..did you figure out what your problem was?
