Headlights stopped working

A cap? Just find the uF rating on it and replace it with a cap with the same rating.

The later model Morimoto relays got away from those small pins that tend to corrode and have much larger spade connectors. This will require replacing the harness but is a simple job. The new harness will mate to the existing ballasts. The capacitors (Small black cylinders) are specifically sized to the LED halo used. You will need to know what size capacitor needed. The Retrofit Source has the harnesses and capacitors as well.

Thanks for all the replies. I bought the Morimoto Harness with Relay. That did the trick!

(I’ll keep searching for the black capacitors)

anyone know the replacement bulb best suited for the old RSIWorks Level 4 HIDs?
