## Questions & Answers

**Q: How can I tell if this is the correct part for my car model?**
A: The best way to do is to take out the original part and check the part number see if it match the cross reference. Other ways is to check Amazon part filter; check owner's manual.

**Q: How to check if it is the bulb or ballast went bad on my headlight?**
A: An easy SWAP TEST will let you find the problem. Try to switch around the not working bulb to the other side (driver/passenger side) to test it. If the same bulb still doesn’t work with the other side’s ballast, that mean it is the bulb’s problem.

**Q: What's included in the order?**
A: 1x Ballast only! Does not include bulb and wiring harness.

### ⭐ Don't Bother. Wonky and Doesn't Last
*by F***Y on November 25, 2025*

Bought this for a 2011 Ford Flex with Xenon headlights. One of the ballasts was bad and this one had decent reviews. Headlight stuck on and tried everything from settings for the time out of the headlights to verifying connections. While troubleshooting, I noticed the light finally went out. Not knowing what I did, I tested turning on and off and it stick on again. After about 10 min, of again. So I timed it and sure enough, 10 min out went off. Thought to myself that I might be ok as long as it shut off. Next day, died completely. Will be sending back and getting one from Rockauto instead.
