Installation Notes and Tips

When installing the Dorman 645-538 turn signal light socket, ensure the vehicle ignition is off and the battery is disconnected to prevent electrical shorts. Carefully remove the old socket by disconnecting the blade terminals and pulling the socket from the bulb housing. Align the new gray round connector properly and press firmly to seat the socket. Verify that the two female blade terminals are fully engaged with the vehicle wiring harness terminals. Since this socket does not include wire pigtails, no additional wiring is necessary if the existing harness is intact. Test the turn signal function before reassembling the light housing.
