It's hard to know what needs to be fixed until a diagnosis is performed to determine why the lights aren't working. If all the bulbs are out, check the fuses and check the dimmer and light switch.
It's not the dimmer. They went out when I changed The bulb for my front right blinker. how do i change the bulb if needed?
