Specs At A Glance

Good To Know

Q: Will this ballast work with my existing D3S bulb? A: It is designed to drive standard D3S Xenon HID bulbs, so it pairs with the bulb already in your housing. Confirm the connector shape on your current unit matches before ordering.

Q: Do I need to replace both ballasts at once? A: Replacing just the failed side is common, though matching both can keep light output consistent. Check each unit for corrosion or moisture damage during the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
