Signs That Your Ballast is Bad
- Dimming or Flickering Headlights. If your HID bulb cannot produce its full brightness or strobe periodically, this is most probably a ballast problem.
- Strange Sounds.
- Headlights Not Working.
- Changing Light Colors.
- Constantly Blowing Fuse.
- Damaged Casing.
- Burn Marks.
- Water or Oil Damage.
Can a headlight ballast be repaired?
It may spark but not fully light up. Fortunately, there is a way to repair it. If this is the case, you will need to reset the voltage and amperage or change the light so that it matches the ballast requirements. Second, try checking the wiring on the ballast.
Does each headlight have its own ballast?
Each of your vehicle’s headlights has its own ballast. These ballasts are commonly mounted either on the back or on the bottom of the headlight. While the HID Xenon Ballasts do commonly fail so can your factory headlight bulb.
What does a ballast do for headlights?
What does a ballast do? The first function of a ballast is to help your lamp start up quickly. When the lamp is turned on, the ballast provides a surge of higher voltage to the lamp. This helps establish an arc between two electrodes on the lamp, which is what causes HID bulbs to light up.
How much does it cost to replace a headlight ballast?
A replacement ballast costs about $10-25 depending on capacity and brand. The bite is that an electrician trip charge (which includes 30 or 60 minutes work) is going to be $75-150 probably – for about 5 minutes work on each light fixture.
What happens when a ballast goes bad?
If the ballast is bad, then the needle won’t move. If you’re using a digital multimeter, often the digital readout will possibly list a “1” when it doesn’t find a measurable resistance.
Can a ballast be repaired?
While simply swapping burned out bulbs in an existing ballast is deemed “ballast repair” by many – and can offer advantages in longevity and energy savings – sometimes this simple “fix” is not enough.
Will LED bulbs work without ballast?
No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or “plug-and-play” LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs. Incandescent and halogen lamps do not require a ballast.
How much does an electrician charge to replace a ballast?
