Frequently Asked Questions (FAQs)

1. Why are headlight assemblies so expensive?

The higher price comes from the simple fact that xenon light bulbs are much more powerful than a halogen, and while a xenon headlight is designed to last much longer than a halogen, it can still burn out eventually.

2. How much is a new headlight assembly?

According to an aftermarket auto part retailer, the cost per each High-Intensity discharge bulb replacement is $100 or more while the average cost of replacing an entire headlight assembly is ranges from $250 to $700. We recommend you replace both bulbs even if only one bulb is faulty.

3. What does a headlight assembly include?

The four main parts of your headlights include the housing, the regular beams, the high beams, and turn signal bulbs. The housing is the hard-plastic cover that you see when you are looking at a vehicle head-on. The regular beams are what is activated when you turn on your headlights or use your daytime running lights.
