Free shipping to the lower 48 · Returns & refunds · Questions? Contact us
Replacement D4S/D4R xenon HID ballast, part DDLT004, for Toyota, Lexus and Subaru vehicles with factory HID headlights. Aftermarket direct replacement for the Denso/Koito unit, not a Genuine Toyota part. Free shipping to the lower 48.
Fix a Flickering or Dead Xenon Headlight
The ballast powers the factory xenon HID bulb. When it fails, the low beam can flicker, cut out or stay dark even with a good bulb. This replacement plugs in where the original Denso DDLT004 unit mounts, so you can fix the light without buying a full headlamp.

What's Included
- 1 x DDLT004 xenon HID ballast (replacement for Denso/Koito)
Installation
- Turn the headlights off, open the hood and disconnect the negative battery cable. Let the bulb cool.
- The ballast mounts on the underside of the headlamp housing. On most of these Toyota, Lexus and Subaru models you will need to remove the front bumper cover and unbolt the headlamp to reach it.
- Unplug the headlamp connectors, remove the headlamp and set it on a soft surface.
- Remove the screws holding the ballast cover/ballast, unplug the bulb lead and remove the old DDLT004 unit.
- Compare the part number on your old ballast to DDLT004 or the numbers listed above, then install the new unit and lock every connector.
- Refit the headlamp and bumper cover, reconnect the battery and test the low beams before final reassembly.
- If the headlamp still does not light, test the D4S/D4R bulb, since a worn bulb can kill a new ballast.
Xenon systems carry high voltage. Never work on the ballast with the lights on.
