My left front headlight had been going out periodically. Took it to a shop and he replaced the ignitor which he said was bad and put in a new bulb. Only now the light emits a yellow shine rather than the bluish color it should. I checked with Acura and he did use the correct bulb? Does anyone know why I mgiht have two different color headlights? thanks.

 

HIDs will change color as they age. Also, the replacement bulb may not have been from the same company as the OEM, which could account for the difference in the color.
