My left brake light went out and I replaced with new one. The next day I noticed in the evening my dash board light was not working and I realized all rear lights were not working either. I would be very grateful if you could tell me what to do please.

Thanks

Start by checking the fuses. There's a fuse box under the hood and another one inside the car. If the fuses are not labelled, the worst way to check them is to remove them for a visual inspection. A much better way is to use a test light. Turn the head light switch on. Each of the smaller spade-type fuses has two tiny holes on top for test points. Ground the test light's clip lead to a paint-free point on the body, then poke the probe into those test holes. If you find twelve volts on both test points, meaning the test light lights up on both points, that fuse is good. If the test light does not turn on at either test point, that circuit is turned off. You're looking for a fuse that has twelve volts on one test point and zero volts on the other one.

If you find a blown fuse, and the replacement blows too, remove the new rear light bulb and inspect the wires on it to see if any are mispositioned and touching.

Morning, thank you. I think the first thing I need to do is treat myself to a test light and will get back to you if I fix it. Thanks again.
