Yellow and amber LED bulbs are becoming increasingly popular for fog lights due to their stylish appearance. However, before making a decision, it’s important to understand the differences between yellow and white LED bulbs in terms of technology and brightness.
White LED bulbs emit a higher intensity of light than yellow LED bulbs, with a difference of about 50 to 80 percent. This makes white LED bulbs a better choice for those who prioritize brightness. However, the perception of yellow light as more effective in cutting through bad weather is a misconception.
Older halogen and low-pressure sodium lights emitted a narrow spectrum of light, which allowed them to penetrate through dust and fog better. LED bulbs, on the other hand, emit a mixture of light colors, including red, green, and blue. When these colors hit particles in the air, they can scatter and illuminate the surrounding area, creating a “warp speed” effect that can be distracting.
Ultimately, the choice between yellow and white LED bulbs for fog lights comes down to personal preference and the desired aesthetic. If you prioritize brightness, white LED bulbs are a better option. If you prefer the look of yellow fog lights, they can still provide improved visibility compared to stock halogen bulbs, but it’s important to be aware of their limitations in certain weather conditions.
