The amber 1157 if I remember correctly.

Ford used #1034 bulbs, very hard to find today. The #1157 is and was the replacement for it. The 1157 was the heavy duty bulb, it has a higher candle power rating than the 1034. Even back then we rarely sold the 1034 bulbs over the counter because we were able to buy the 1157 at half the price in quantity so that is what most stores stocked.
