On the 1995 Toyota Corolla the tail lights are three colors, red, amber, and clear for back up lights.
The lights are designed to use two bulbs for the brake lights and driving lights. The backup light and turn signal light is done with one bulb, so there are four bulbs in each tail light.
When one of the brake lights burn out it can give drivers following a confusing signal when you put on your brakes because one bulb will go out and the other will glow bright and that almost looks like the turn signal is turned on. So be sure to check the bulbs often.
To change the bulbs on a Corolla you need to actually remove the tail light to get at the bulbs. When you remove the tail light pay particular attention to the gasket that seals out the weather from the trunk. If you notice that the gasket has been ripped it will need to be repaired before you replace the light assembly so water doesn't get into the trunk.
The tail light assembly is a sealed unit and the only access point is the socket where the bulbs attach.
If for some reason a tail light assembly gets broken it should be replaced to prevent leaks and to keep the vehicle in compliance with traffic laws and safe.
