Hi Paul, welcome.
These lights all get tripped at once when a wheel speed sensor has malfunctioned. It could be a bad sensor or a dirty connector or a pinched wire. It could also be a rusted out tone ring (that the sensor reads) inside of the hub, depending on if you live in the rust belt.
Best thing to do is go somewhere that they have a scanner to read ABS codes, so you can find out which wheel the problem is at. Try an auto parts store — they usually read codes for free.
