These lights will appear when the abs control module registers a fault in the system, and there are many different faults that can make the light come on. If the shop replaced a wheel bearing for this problem then you may be getting a wheel speed sensor fault. However, if they said this would fix the problem, and it didn't, then they may not be properly diagnosing the problem. ABS Control Modules are problematic an many vehicles, and you have an issue with it, but a proper diagnosis should reveal this. I would say you should take it to another shop, and try to get a refund from the shop that took your money and didn't fix the problem.
