Not on the Disco, but on the prior deceased vehicle, I swapped out the H4 headlights for JDM H3 Projectors and they made a most apparent improvement. Since I had to also drop in a new wire harness, I suggest that a new wire harness with direct battery connections would make a great improvement with OEM H4s or newer 80/110 or higher power output bulbs on the Disco. If I can find the same wire harness, I will attempt it and bring news after the spring thaw.RoverAsh said:Are the newer style light any better than the original Disco II lights? Do they project more light or a better beam pattern?
