While the retrofit of an H4 bulb in an 8" reflector will allow you to use a hi/low bulb you do not get the true hi beam and low beam. The lens of an H4 reflector is cut to give you the cut off for low beam. On low beam all that will happen is the light output will be cut by 5-20watts (depending on the bulb) but will have full dispersement just like the stock 8" desert style reflector with no low beam cut-off. Hi beam will be pretty much the same as the stocker. The pattern of the beam will also depend on how you arrange the bulb in relation to the reflector.
I know you mean well by posting your discovery in my Vendors thread but I produce these conversions for people that need an approved light to be street legal. This is the Vendors Section, if you feel so passionate about your modification please start a thread of your own in The Garage.
Thank you, Scott
