If it lights up, you know the relay is good. As modern vehicles electronics can be damaged easily. One of the most common reasons for indicators to be flashing fast while you are indicating is a blown bulb. For example, a solid turn indicator for a left turn, with the front turn bulb on constantly, but no left rear turn bulb illuminated, indicates that the left rear turn light bulb has failed.
