Where is the flasher located at on a 1996 Chevy s10 tail lights?

The flasher relay for a 1996 Chevy S10's turn signals (which control the flashing of the tail lights as part of the turn signal function) isn't located *in* the taillights themselves. It's typically found inside the vehicle's passenger compartment, usually within the fuse box or under the dashboard. The exact location can vary slightly depending on trim level and options, so checking your owner's manual or a wiring diagram specific to your year and model S10 is the best way to pinpoint it.
