1965-1967 Thunderbird turn signal indicator relay
This relay is located under the dash of 1965 thru 1967 Thunderbirds. It controls the flashing of the fender mounted turn signal lights in 1965 and 1966 and dash turn signal lights on the 1967. If your turn lights in these locations blink once and then stay on you have found the culprit. This new modern version will restore your indicators.
