Having already upgraded the headlights and added a powerful light bar to our 2014-2021 Toyota Tundra, we felt it needed some love in other lighting departments. Today we will look at upgrading the taillights, front blinkers, and a variety of interior lights.
Unfortunately, these lights are not all the same. To make things easier on you we will go through each light to cover all the basics of the bulbs and installation. We will also discuss a few safety precautions you may need to take when installing new bulbs and how to install a resistor.
TURN SIGNAL
If you are already in the process of installing your headlights, this project will be super convenient for you. To install the turn signal bulb you will need access the back of the headlight from the engine bay.
Start by popping the hood and reaching the back of the headlight. Find the 7443 Incandescent bulb and turn it counterclockwise.
INTERIOR LIGHTS
All those incandescent bulbs dotted throughout your interior provide a dingy experience when sitting in the car. They are super dull and in need of an LED swap. You can use something from that pry tool kit
We will start with your map light. First, pop off the plastic lens to reveal the T10 bulb. Do not remove the bulbs with your fingers as they are extremely hot. To remove them, use a pair of needle-nose plyers.
If the light does not come on at first, turn the bulb 180° and plug it back in. These lights are polarity specific so they will not turn on in certain positions. Then you can put your plastic cover back on.
EXTERIOR LIGHTS
To begin on the exterior of the car, we will replace the T10 bulb inside the license plate lights. This upgrade is huge for your vehicle. It may seem insignificant, but it can do a lot for the overall appearance of your Tundra.
