A ballast is a crucial component of your entire headlight system. Its primary purpose is to control the intensity of your car headlight. It also controls the intensity of the bulbs so that they are not using up all your power.

Can a headlight ballast be repaired?
Not all failures require a replacement; sometimes it is because of a damaged ballast. By resetting your ballast, you can make it work again, extend its operational life, you save money in the long run.
What does the ballast do on a xenon headlight?
XENON BALLASTS: FUNCTION The electronic ballast controls the start-up of the bulb so the bulb reaches its operating phase quickly, and then controls the bulb power to a constant 35 W. A DC converter generates the required voltage for the electronics and the bulb from the vehicle electrical system.
Do xenon headlights need a ballast?
In order to keep your Xenon HID lights working properly, you’ll need a HID ballast. The ballast is an important part of your HID light setup and is essential if you want your Xenon HIDs to work properly.
Is it worth replacing a ballast?
For energy savings, reliability, and longevity – replace ballasts – not bulbs. In addition to energy efficiency issues, older ballasts simply do not offer the reflection geometry newer options do.
How much does it cost to replace a headlight ballast?
A replacement ballast costs about $10-25 depending on capacity and brand.
How do you know if your headlight ballast is bad?
Signs of Ballast Failure But there is a good chance your ballast could be the cause of your lighting woes if your lights are dim, buzzing, changing colors, or flickering rapidly. You should check all parts of the fixture, including the bulbs.
How do I know if my ballast is bad?
- Flickering.
- Buzzing.
- Delayed start.
- Low output.
- Inconsistent lighting levels.
- Switch to an electronic ballast, keep lamp.
- Switch to an electronic ballast, switch to a T8 fluorescent.
What happens when a ballast fails?
The ballast provides enough voltage to start the fluorescent bulbs, and once they are started, it quickly lowers the current to produce just enough electricity to produce a steady light source. Without the ballast, a fluorescent bulb would attach directly to 120-volt current and quickly burn out the bulb.
How often do HID ballasts need to be replaced?
How long do HID ballasts last? Some survive for 3-5 years. If they’re well-maintained, ballasts typically last for up to 20 years.
How long do xenon ballasts last?
A well maintained ballast can last up to 20 years, which is multiple times longer than a bulb’s lifespan.
Can HID bulbs work without ballast?
Incandescent and halogen lamps do not require a ballast. Like we mentioned, you just screw them into the socket, and you’re done. Fluorescent lamps and HID (high intensity discharge) light bulbs do require a ballast. Both lamp families use two different types of ballasts: magnetic and electronic.
What’s the difference between 35w and 55w ballast?
You will get about a 50% brightness increase by going from a 35-watt ballast to a 55-watt ballast. So the 8,000K HID bulb will go from 1,000 maximum lux to 1,500 maximum lux at 25 feet, but the color will shift to a 6,000K color. Just because your HID bulb says 10,000K or 12,000K does not mean that it is brighter.
Can you use 35 watt HID bulbs with 55 watt ballast?
All parts of the HID kit should be of the same wattage. It means that 35W ballasts should be used with the 35W bulbs and 55w ballasts with 55w bulbs.
Will a 35 watt HID bulb work with a 55 watt ballast?
Yes. Actually, a 35w 5800k Xenon Bulb means: At 35w, the output colour will be 5800k. If we connect 55w ballast to 35w 5800k Xenon Bulb, the colour will shift to around 5000k approx.
Can you replace a ballast yourself?
A typical ballast will generally last about 20 years, but cold environments and bad bulbs can decrease this lifespan significantly. You can get a new ballast at a hardware store or home center and install it in about 10 minutes.
Can Ballasts be fixed?
Sometimes, the colour coding on the old ballast does not match the new ballast. We recommend that you always hire a qualified electrician to have a ballast repair or ballast replacement service done.
How do you check a ballast?
How do you replace a ballast?
Why are my high beams not bright?
The most common reasons why headlights don’t get bright enough are that they either a lack of voltage in the circuit, the wrong size bulb, or the lens of the headlight is oxidized or faded. If this occurred right after the lights were replaced I would suspect that the wrong bulbs were used.
Why are my headlights not working?
The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse. Consult your owner’s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
Which is brighter xenon or LED?
One reason xenon lights have gained in popularity is their extreme brightness. It’s often brighter than both an LED light and a standard headlight. These brighter headlights do come with a trade-off, though. They use much more energy than LED light.
What causes HID headlights to go out?
One of the most common issues with HID systems is improper installation. The bulb, the ballast, and the wiring all need to be firmly and tightly installed, and hidden from moisture. HIDs also need to be grounded properly to function correctly, and improper grounding is a common installation error.
How do you fix low beam headlights not working?
You’ll need to replace the bulb, switch, or relay. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch.
