I own a 1997 Toyota Camry LE 4 cylinder, I have changed all the brake lights but whenever I tap on the brakes, the yellow "change buld" symbol" pops up and The bulbs are installe correctly and snug.

excuse my typo, bulb*

Have you actually had somebody stand behind the car while you push on the brake, and make sure they all work? Are they a multi- bulb led assembly, if so even one led not working will cause that

Yes, my father did and he saw all the 3 brake lights came on when I tap on the brake pedal. No the car does not have LED brake lights
