Re: Modern Ignorant headlights

half way to full retard..

A little follow up. Using the MSD relay is the only way to go,, so clean and easy.. has neg or pos trigger.

The Cruise control stem has 3 events;

ON= blue/Green constant to ground.
Set= Blue/red momentary contact to ground.
Resume=Blue white, momentary to ground.

I am using the OEM high beam to affect the OEM high beam,,
High beam does not turn off low beam using a 50 cent resistor
I might swap out the 4703 LB for 4701 HB. ( 4 on at the same time for high)
Set of Bumper Hella Black Magics turn on with the ON of cruise control.


I still have SET and RESUME for two more events using a latching relay. I may use SET for train horns since that would need a momentary action.


If I still need more, (passed a Rivian tonight) I will double up.


I know I am a geek using the Cruise stem but hate adding garbage to the dash. On my 67 race car, (no wipers) I repurposed the wiper knob for electric fans/pumps etc. It also has three events, low/high/washer.
