Thanks! Cars are getting more complicated with the computers and electronics for sure. I found this relay that has an adjustable delay that could keep the headlights on for up to three minutes after the ignition is turned off. It fits a standard 12v automobile relay harness so it is plug and play. http://www.qualitymobilevideo.com/bu508td.html
OMG! I watch those guys all the time on Youtube but I swear I have never seen that episode! I'm glad I didn't or else I wouldn't have figured out how to do it with only one relay without cutting any high power wires to the headlights.
I thought about that and I guess I could wire two relays both in parallel for redundancy but there are many relays in a car and any one of them could fail at any time. I agree none are as critical as the one for your headlights so I did tell my son that if his headlights go off while driving he should pull back on the stalk (for flashing your headlights) and hold it until he can pull over safely.
It would 99 times out of a 100 but just in case he forgot that one time... And I probably did it more for his convenience more than anything else. Turning off your headlights is so 80's :)
Thank you! I've noticed the ends of the wires corrode very quickly so I have to pull it down a quarter inch every month or so and snip off the ends. Luckily I have 20 extra feet coiled up in the attic! Also I've discovered I don't even have to strip the wires, just cut it. The water contacts with the copper inside the insulation just fine which is great so I don't have to worry about any wire slivers getting into their water.
