The bulb sizes on the JDM lights are (1) H4 and (1) H1. On my car, I have the the H1's wired up for my high beams. Does anyone know if there is way to wire up the H4 bulb so it's used as a dual beam like it should be. I put some Eurolight H4's in in my headlights and they look good but don't light up the road too well. PIAA bulbs are great but cost a lot.
