This 1968 Datsun 2000 came into the shop for some odds and ends and we thought we would use it to illustrate a common upgrade that many owners choose to make. What we do is add relays for the headlights and any driving lights. The idea is to take the electrical load off of the decades-old dash switches and move it to the new relays. The dash switches then simply switch the relays. Just a simple little touch to make everything a tad more robust.
