Re: [Funky tech] Lighting: 5th relay?

["Rich Zuk" <emt@imcnyc.com>]

Objective:  To have the H4 lows come on, via on-dash toggle switch, along
with the H4 highs and H3 when the high beams are selected.  This enables me
to have the option of getting extra light, if i choose to, when the high
beams are turned on.

>right now you have one relay for each of the low beams, right?
>when you turn the high beams on, that's the other two relays doing that,
right?


I have 4 relays.
Driver side lows / Drivers side highs / Passenger lows / Passenger Highs

>when the high beams are on, only the two high beam relays are activated,
>the other two low beam ones are off.

Low Beams:   The H4 lows come on with low beams.
High Beams:  The H4 highs and the H3 comes on.

Correct me...Connect a jumper wire between the two wires that enter terminal
86 of the Driver side low relay and terminal 86 of passenger side low relay.
Then attach a wire that leads from the toggle to this jumper wire.  So when
I toggle switch to on, the 2 low beam relays will be activated.  Causing the
H4 lows to come on while the H4 highs and H3 are on.  So we are tricking the
car into believing that the toggle switch is an extra low beam activator, my
original desire.  So the 5th relay won't be needed because I'm now using the
existing 2 low beam relays for their intended purpose. ie, handling H4 low
beams.  I had it such that the 5th relay would handle both of the H4 lows.
So If i do it this way, is it safe?
I wonder if this is what Andre was trying to explain to me.

Hold on!   One thing at a time my friend!
