Performance & Visibility Section
Environmental moisture and road spray around the headlight housing can lead to premature ballast issues if the surrounding seal deteriorates or loses tension. Replacing an old or flattened gasket with a fresh Denso Koito DDLT-003 rubber seal helps ensure a tight fit between the ballast module and headlight housing. Sourced through HID Concept.com, this genuine Denso Koito replacement component helps maintain proper enclosure sealing for your vehicle's xenon lighting setup.
OEM Quality & Reliability Section
Reusing an old or compressed gasket when reinstalling or replacing a ballast can compromise the housing seal. Sourcing authentic Denso Koito hardware through HID Concept.com ensures exact dimensions and proper fitment for DDLT-003 ballasts. Replacing the rubber gasket during ballast service provides an easy way to help protect your replacement or existing OEM lighting hardware.
Note: HID Concept recommends inspecting the rubber seals on both headlights when performing ballast maintenance.
Installation Information
The Denso Koito DDLT-003 rubber gasket is designed to fit directly into the perimeter sealing channel on the ballast housing.
To install, clean the ballast mounting channel and headlight seating area of any dirt or residue, then press the rubber seal firmly into the perimeter channel before securing the ballast onto the headlight housing.
