Overkill 4-relay set to provide maximum power to the lights. Includes 4 fuses and heavy gauge wires from the battery all the way to the headlights.
No wire cutting or crimping required. Will require work in the wheel well, jacking up of the car and possibly temporarily moving the washer tank and oil cooler for access.
Quality Zettler relays. Optional German relays are also available.
With LED lights becoming more available, the current draw is not as much of a concern as with halogens. However, LEDs are voltage sensitive. It is still a good idea to install relays to prevent your LED lights from flickering or turning off due to low voltage from the unreliable switches.
Relays are traditional cube style. You can get replacement relays at any parts store so there is no worry of being stranded waiting for special parts in case of (rare) failure.
Wire lengths are not sized for '73 or older 911- this is not a universal fit product.
Does not fit 914 or 914/6.
