Product Overview

ORACLE LED Replacement Bulbs are direct OEM replacement units designed to drop into your 1975-1987 Ford F-150 rear turn signal without modification. They deliver a Quick-Fire response that illuminates faster than factory incandescent bulbs for sharper, more visible signaling.

Built on 5050 SMD chip technology with 18 LEDs, these bulbs produce vibrant, sharp-hued light at 270-306 lumens while consuming only 1/10th of the power of the factory bulb. Each chip is rated for 100,000 hours of continuous use.

Load Equalizer Required: When installing SMD bulbs in a turn signal circuit, a load equalizer (resistor) is required to prevent hyper-flash (rapid blinking). Load equalizers are sold separately.
Key Features
  • Direct plug-and-play OEM replacement - no wiring modifications required
  • 18 LED 5050 SMD chip technology for vibrant, high-output light
  • Quick-Fire response - illuminates faster than stock halogen bulbs
  • 270-306 lumen output for strong turn signal visibility
  • Consumes only 1/10th the power of the factory bulb
  • 100,000-hour chip rating for long-term reliability
  • Available in Cool White, Red, and Amber
  • Sold individually (single bulb per package)
  • Backed by ORACLE's 1-year warranty
Load Equalizer Required: Turn signal circuits detect bulb resistance. SMD LEDs draw significantly less current than halogens, which triggers hyper-flash without a load equalizer. Install one per bulb socket. Load equalizers are sold separately.

Installation Guide & Resources

Installation is a straightforward plug-and-play process. No wiring modifications are required for the bulb itself.

  • Locate the rear turn signal housing on your 1975-1987 Ford F-150
  • Access the bulb socket from behind the tail light assembly (refer to your owner's manual for the access method on your year/trim)
  • Twist and remove the existing 1157 halogen bulb
  • Install a load equalizer inline with the bulb socket to prevent hyper-flash
  • Insert the ORACLE SMD bulb into the socket and twist to lock
  • Test the turn signal function before reassembling
  • Repeat for the opposite side
Load Equalizer Required: Turn signal circuits detect bulb resistance. SMD LEDs draw significantly less current than halogens, which triggers hyper-flash without a load equalizer. Install one per bulb socket.
