Electrics / Re: H4 headlight

« on: September 25, 2020, 08:40:02 am »

Hello,
my very simple H4 bulb connection:
I tied everything behind the new H4 headlight, next to the fuse holder.
I used two ordinary 12V DC 20A car relays.
I brought + 12V to the relays from the fuse holder (line coming from the main ignition lock running through the fuse). To control the relays I used lines coming from the light switch to the old bulb one for the long and the other for the short beam. For - 12V I used an existing line in the headlight.
regards Feistko

Hi,
I bought on ebay for 40EUR
https://www.ebay.de/itm/Honda-CB-350-Four-CB-400-Four-H4-Einsatz-neu-Reflektor-154mm-reflector/362968712928?hash=item54829f06e0:g:n6sAAOSwQTVV~BdD

Fits allmost perfect. BUT I recommend using relays between the original switch and the H4 bulb. H4 consumes about 50% more current. The switch contacts will wear out sooner. I mounted two switching relays, one for the short and the other for the high beam.
