Product Overview ▼

ORACLE 1157 LED bulbs are direct OEM-replacement bulbs with Quick-Fire response - brighter and faster-illuminating than stock halogen bulbs. This listing is fitment-verified for the front turn signal position on 1975-1977, 1981 Ford F-150 trucks.

Built with 18 LED 3-Chip SMD technology, these bulbs produce vibrant light with sharp hues while consuming only a fraction of the power of the factory bulb. Rated at 100,000 hours for continuous use.

Some fitment guides reference this application as "1157NA" (Natural Amber) - this is the same 1157 bayonet base bulb; select the Amber color option below for a factory amber-matched turn signal.

Sold individually. Available in Cool White, Red, and Amber.
