Every light on your Cadillac is very important when driving, and if any of them are in disrepair, the problem should be taken care of immediately. This is especially true of the Cadillac turn signal light, because if it is not working, it could lead to an accident, or, at the very least, angry stares from other drivers. In most cases, the problem is that the bulb has burned-out, which generally happens about once a year. The bulb of the Cadillac turn signal light is very easy to replace, and inexpensive, as well. You will find the correct bulb for most vehicles in our large online catalog, in stock and ready to ship. To install the bulb, simply remove the Cadillac turn signal light assembly, grab the wiring harness, and give it a counter-clockwise twist to remove it. Take the old bulb out of the harness, put the new one in, and reassemble the unit. If the Cadillac turn signal light is not blinking, the problem is probably a bad flasher, which is located in the fuse box. It is easy to replace and we also carry it in our online catalog, for a low price. If there are any cracks or other deficiencies in the housing of the Cadillac turn signal light, the entire unit should be replaced to avoid future electrical problems. We carry a unit that looks exactly the same as the original, at a much lower price that what the replacement would cost from the dealership.
