ODX Lighting RELAYH11 Relay Harness with Capacitor H11 H8 H9 Socket

The ODX Lighting RELAYH11 is a relay wiring harness with integrated capacitor designed for H11, H8, and H9 bulb socket applications. This plug-and-play harness is an essential accessory when upgrading to HID or LED lighting systems, ensuring your bulbs receive stable, full-voltage power drawn directly from the vehicle's battery.

Factory headlight wiring is engineered for standard halogen bulbs and may not deliver adequate or consistent power to aftermarket HID ballasts or LED drivers. The RELAYH11 solves two common upgrade problems: low-voltage flickering caused by insufficient current from the factory circuit, and PWM (pulse-width modulation) or DRL-induced strobing. The built-in capacitor smooths out pulsed signals from modern vehicle electronics, while the relay provides a clean, dedicated power path from the battery to the headlight socket.

Key Features:

• Compatible with H11, H8, and H9 bulb sockets — ideal for low beam, high beam, and fog light HID or LED upgrades
• Integrated capacitor eliminates PWM flickering and DRL-related strobing common in 2008+ vehicles
• Relay draws power directly from the battery for full, stable voltage delivery to HID ballasts and LED drivers
• Plug-and-play design connects directly to the factory H11/H8/H9 harness with no cutting or splicing required
• Protects factory wiring from the increased current demands of aftermarket lighting
• Lifetime warranty backed by ODX Lighting

The ODX RELAYH11 relay harness with capacitor is the recommended companion accessory for any H11, H8, or H9 HID or LED conversion kit, providing reliable performance and protecting your vehicle's electrical system from the demands of high-output aftermarket lighting.
