I am looking to upgrade the weak sealed beam headlights. In my Jeep CJ, I upgraded to Halogen bulbs in a newer model housing and used a harness that tied into the headlight connectors and has relays built in so that all of the voltage does not run through the switches.
Has anyone done something similar to their impalas? If so, what was used? For the headlights, I assume I could use the same housings as my Jeep since they are the same size. But what about the high beams? The Jeep has high and low in the same light. The impala has those for the outside but also has hi beam only in the center. Not sure what to do about those.
