Capacitor Link

Capacitor link

More and more modern vehicles are coming from the factory with headlight circuits that run on pulsed voltage to run things like Daytime Running Lights or as a means to prevent owners from changing their lighting system. Certainly a problem, but not with the right tools to fight back!

When running HID's on a vehicle with a pulsing headlight circuit, the ballasts will flicker/flash even if you install a relay harness - since the pulsing current will translate into the relays, which will click on and off rapidly (often sounds like a buzzing noise)

This capacitor link will solve that issue by absorbing that pulsing voltage, storing it as its own charge, and releasing it smoothly into the relay harness. Simple plug n play installation between the factory output and the harness input, with just one ground to connect.

Utilizes one 4700mf electrolytic capacitor, 14 gauge wiring, and OEM-quality 9006 Male/Female Input/outputs for compatibility with nearly all low-beam relay harnesses.
