My blinkers brake reverse all works, no bad fuses need to know what to look for

The tail lamp fuse is blown. Possible shorted bulb or light socket.

Test all under dash and under hood fuses with a test light or multimeter. You want to test for "power through the fuse." Turn the ignition switch to ON, and, using a test light or multimeter, test for power at each test point on the fuse. If some fuses fail the test, the ignition switch may be bad, due to wear, pitting, or melting. The flow is from the + battery terminal, to the under hood fuse box, to the ignition switch, to the under dash fuse box, to each light. Therefore, it's easy to visualize how a bad ignition switch can prevent power to, for example, dash lights. A visual inspection of fuses may show they are good, but, because the ignition switch is bad, various circuits are not receiving power. Be very thorough, since it will save a lot of time and money.
