depos do have a lhd pattern: the beam flares up to the right, away from oncoming traffic. i think the beam patter is better than stock, sharper cutoff, and the h4's light up the road much better, kinda like my mom's slk230

i havent had time to wire the highbeam in the h4. the only thing u need is a relay to switch off the low beams when the high beams are on (the heat from both filaments will blow the bulb).
my h1's are wired to my factory fog switch now and aimed lower, like aux. driving lights.
