Race Sport RELAY-CAP 12V Relay Harness with Capacitors for HID LED Kits

The Race Sport RELAY-CAP is a heavy-duty 12V relay harness with integrated capacitors designed specifically for HID and LED lighting kit installations. This multi-purpose interface harness solves common voltage and flickering issues that occur when upgrading to aftermarket lighting systems.

Key Features:

• Built-in capacitors stabilize voltage and prevent light flickering on vehicles with daytime running lights (DRL)
• Retains factory daytime running light function when installing HID or LED headlight upgrades
• Handles low voltage inputs (6-11V) and keeps relay operational for proper function
• Compensates for pulsed voltage systems instead of steady voltage, maintaining consistent relay operation
• Takes the load off factory light circuits and ensures constant 12V+ power to HID ballasts or LED drivers
• Heavy-duty construction for reliable long-term performance
• 1 year manufacturer warranty

This harness is essential for vehicles that experience flickering, bulb-out warnings, or inconsistent lighting performance after HID or LED kit installation. The integrated capacitors work with the relay system to provide stable, clean power delivery. Proper polarity installation is critical—ensure 12V+ and ground connections on the vehicle's light plug match correctly with the trigger plug connections on the harness to prevent damage and ensure proper operation.
