Cost, Parts Included, and Diagram of a Mazda Headlight Assembly

As a Mazda owner, you’re probably wondering what’s in a Mazda headlight assembly. In this article, we will cover all the components included in a Mazda headlight assembly and then discuss the costs associated with them.

Components Included in a Mazda Headlight Assembly

If you take apart a Mazda headlight assembly, you’ll find a variety of components inside. Here’s a diagram of the OEM headlight assembly for 2010-2011 Mazda 3 models and a list of all these parts:

Light assembly

  1. Headlight housing and lens
  2. Screw
  3. Nut
  4. Rivet
  5. Headlight bulb
  6. Headlight bulb
  7. Cover socket
  8. Turn signal bulb
  9. Socket
  10. Control box
  11. Screw
  12. Gasket
  13. Harness (also called cord lamp head)
  14. Repair bracket

Each Mazda headlight assembly has its own unique design, but all halogen headlight assemblies work the same way. There’s a reflector in the headlight housing. The headlight bulbs shine against the reflector, which then disperses the light ahead of the vehicle. This function is supported by all the components inside the headlamp assembly.

Mazda Headlight Assembly Costs

When it’s time to fix or replace your headlight assembly, you may be wondering how much it’ll cost you. The quick and straight answer is: it depends. The Mazda headlight assembly cost varies between models. Some Mazda headlight assemblies are more complex than others.

For example, part number GJS1-51-031C (OEM headlamp for 2014-2017 Mazda 6 models) has a simpler design than part number FF16-51-041C (OEM headlamp for 2009-2011 RX-8 models). That’s why the former is at least $225 cheaper than the latter.

If you don’t want to buy a whole new headlamp assembly when you know exactly what the issue is, we have good news. In some cases, you can buy a replacement component (such as a bulb) and replace it yourself. Do a search on your Mazda model in our catalog to see which replacement headlamp assembly components are available for your car.
