47 What do the H1, H2...H4 designations mean?
there are many types, but yours are 9004.
that number is a specific type lamp, and some strange cos. sell them in colors.
that is illegal here. only the orig. are legal here but that dont stop.
by the way independant human studies have proven that the normal lamps
that have yellow natrual cast of light as in tungson , alow l our eyes better and farther.
so all this jive and hype you read is , well , just that.
and of course brighter is better but over 45w/65w ( will probably smoke the oil wires)
you need new head light shells. I got one from fleebay cheap, new is outragious.
Oem is like $160 , and then adding ship to Ireland....
just be patient and find one at a time. left and right.
also put in wanted to buys here in the classified section.
good luck and be careful at night.
