Voltage drop on headlights

From : carolina watercraft works

Q: 01 2500 4x4 v8 sport package i seem to be getting a voltage drop to my lights when my high beams are on. im ok with low beams but id like to find out why my highs are not up to spec. ive noticed that the high beams just are not as bright as they used to be and are barely better than when on low. is there a known voltage drop issue with the switchs on high what are my options including adding the relay wiring modification i recall reading about any thoughts from the group -- ------------------------------------------ laszlo almasi ----cool toys ----mack daddy trailers ----ice angels .
