Why is my Toyota headlights so dim?

Why are my Toyota headlights so dim?
Dim headlights can be caused by several factors. Here are some possible reasons:
1. Dying or burnt-out bulbs: The most common problem with dim headlights is old or burnt-out bulbs. Headlight bulbs, like the lightbulbs in your home, need to be replaced periodically.
2. LED vs. Incandescent bulbs: If you are driving with traditional incandescent bulbs, LED headlights can appear much brighter in comparison, making your headlights seem dim. LED lights emit a sharp white light with bluish tones, which can be harsher on the eyes.
3. Worn alternator belt: Headlights that brighten and dim at random intervals may indicate a worn alternator belt. The alternator belt connects the alternator to the engine, and if it is old and worn, it may alternate between slipping and gripping, causing the headlights to lose power and dim.
4. Dirty ground connection: A dirty ground connection can also cause dim headlights. Cleaning the ground connection and applying dielectric grease can help restore brightness.
5. Hazed lenses: If the lenses of your headlights are hazed, they can reduce the brightness of the headlights. Polishing the lenses can help clean them up and improve the light output.
It’s important to diagnose the specific cause of your dim headlights to determine the appropriate solution. If you’re unsure about how to proceed, it’s recommended to consult a mechanic for further assistance.

Does headlight restoration increase brightness?
