Dim headlights are one of the most common signs of a failing D1S bulb. If your headlights are not shining as brightly as they used to, it may be a sign that the bulb is nearing the end of its lifespan.
Headlight Bulb Flickering
Flickering headlights can be a sign of a failing bulb. If your headlights are flickering frequently, it’s likely that the bulb is on its way out.
Dim Pink Glow
A dim pink glow from your headlights is another indication of a failing bulb. This is often accompanied by a reduction in the bulb’s overall brightness.
Constantly Blowing Fuses
If your fuses are blowing frequently, it could be related to a failing D1S bulb. This is especially true if the fuses are blowing only when the headlights are in use.
Low Beams Not Working
If your low beams are not working properly but your high beams are functioning fine, it could be a sign that the bulb is failing.
No Headlights Working
If none of your headlights are working, it’s likely that the bulb has failed completely.
