bulbs do produce a bit of heat, i believe that's normal. as for driver side not projecting as far, would that be because you're sitting in the driver's seat? hence more weight in the front RHS, so more of a dip in th RHS headlamp. although i don't experience this in my 05 levin, but i do experience the same thing in my 01 camry. in the camry the passenger side light projects further then the driver side.
