H4 Headlight Wiring

[Denis]

I did use 2 relays, one for low and one for hight. So the check always tell
me one buble is bad ... it buzz all the time i change hight to low beam...
bugs meI have to rewire for more relays,, its very simple. With 4 relay no
problems, but the check lll still  not work. The auto check send 12 volts to
the light and if its bad, it warn you. And with the relays , the autocheck
ll send 12 volts on the relays not on the buble, so it ll not tell u if its
burn, it ll  tell u only if the relays  is bad, not the buble. At leats u ll
not be bugs  by the autocheck buzzer.
