yes, it lights up only when brake is applied
tail light lamps are bad
Where is the switch located for the back up lights on a 2000 cadillac daville
In the middle of the light bar across the back. It is a single filament bulb 3156LL.
running or parking lights, or plate light, but that is singular.
Need a better definition on "wing" tail lights. In the late 40's through late 50's, the Cadillac had tail lights at the top back of the rear quarter panels. 1956 was the last of the tail lights at the very top of the quarter panel. 1950 through 56 tail lights were more like bubbles at the top of the tail fin. In 57 and 58, while models varied on tail light placement, the tail light lenses were more "aerodynamically" shaped with the car. In 1959, the tail light lenses took on a bullet shape, and while near the top of the quarter panel, they were not at the top of it. Throughout the 60's, while the tail lights remained in the "wing" they were not at the top of it. This remained the trend until about 1964, when the tail lights took up the entire up and down length of the quarter panel end. In some Caddys, this is still the trend. However, in Eldorados, Sevilles, and other models of Cadillac, the tail lights could be up and down, across the back, or even square (for example the 1976 through 1979 Seville).
All CMVs must have seven lights across the back.
It's a ground fault in one or both of the brake lights. Instead of brake light voltage going across the bulb and to vehicle ground, it's going across the brake light then back across the tail-light and into the tail light/dash light circuit. Check the brake light sockets first. Saturn had some problems with some of their tail light assemblies corroding from too much heat when lights were on for an extended period of time. You might be able to just clean up the connections in the tail light assembly then put it all back together with a little of the special grease that they use for light sockets. If that's not it, check the ground wire and make sure it's getting a good connection.
my back brake lights don't work, but the brake light on the back door does what could be wrong
Put a jumper wire across the terminals on the switch if the lights work (with ignition switch set to "on" position) switch is defective
The check engine light on a 1999 Cadillac DeVille can be reset by disconnecting the battery for 30 seconds. The light will immediately come back on if the problem still exists.
The back up light switch is stuck closed or broken.
Lights and torches with a shiny back have a reflector component that helps redirect and focus the light emitted by the bulb forward, improving the overall brightness and efficiency of the light source. This design enhances the reach and intensity of the light beam produced by the device.
