Isuzu NPR Turn Signals

It is important to have a working knowledge of your Isuzu NPR to maintain it properly. The turn signals are just one of many essential safety features on your truck that you should always keep in working condition. The parts are accessible and can be replaced if necessary.

What are turn signals used for?

There are two turn signals at the front of a vehicle and two at the back, each on the left and right sides. These are also called indicators as they are used to signal to other drivers, pedestrians, and cyclists which way the driver intends to turn the Isuzu. The driver uses them when changing lanes or turning in the NPR. In the same lamp casing, the hazard or emergency lights will flash in unison when activated to warn others that the driver is experiencing a problem or to bring awareness to the vehicle and its location.

What are signs of a damaged turn signal?

Driving your Isuzu NPR with damaged or failed turn signal lights can be dangerous as they are intended to maintain safety and order on the road. If you experience a problem with one of your four lights, address it to ensure that you and others are safe while you are driving.

  • Quick flashing - If the indicator light on your dashboard is flashing faster than it normally does, this tells you that one of the bulbs on that side is out.
  • Cracks or holes - If there is visible damage to a signal light, it is practical to replace the part. When water and debris have the ability to enter the light, it can cause further damage to it or other parts.
  • No illumination - If the signals are not lighting up, there is a clear failure with some aspect of it. If the bulb is not dead, the bulb socket or the wiring could be damaged. When both the front and back lights are not working on the same side, this indicates a further problem in the system.
How do you change the turn signal lamp?

When preparing to change the light assembly, it is important to read the owners manual for your Isuzu NPR to ensure proper installation. When necessary, be sure to wear safety gear.

  • Access the damaged lamp from under the hood or in the trunk area of the car.
  • Remove the bulb and socket from the lamp.
  • Unscrew the light assembly and remove it. Place the new one in and attach the screws.
  • Reinstall the socket and bulb. To prevent premature failure, do not touch the bulb with your bare hands or wipe it after installation.
