Insurance for high watt lightbulbs in the head lamp. Basically, you put the bulbs in without it and parts of your SC will turn into chicharron.

It is a "Competition Only" headlight wiring kit.

The main thing this kit does is leave the low beams on when the high beams trip. Stock cars turn off the low beam when the high beam is turned on.

To do this, you also gain the benefit that the headlights are no longer part of the load on the Multi-Function switch as Relays are also installed. This significantly increased the life expectancy of the multi-function switch.
