Switchback 7440 LED Turn Signal Light Installation Guide

This DIY is to demonstrate the installation of the iJDMTOY 7440 Switchback LED Bulbs and replacement LED Flasher unit.

The bulbs will appear as DRL's and illuminate white with the parking lights on. They will flash amber when the turn signals are used.

The LED Flasher Relay will allow the LED lights to flash at the factory speed without the need to install resistors at each lamp location.

The installation will require several small hand tools and some wiring skill.

Needed for job:

2 LED Switchback 7440 Turn Signal Bulbs
1 Toyota LED Flasher Relay
2 Inline wire connectors
Vinyl tape
10mm socket and ratchet
Phillips screw driver
Flat head screw driver
