Headlight question?

[eeh1025]

Hey there when you put your high beams on what happens, does both filliment in the bulb turn on?

Assuming this is an 87-93, no. Only one filament will be on at a time, unless you have your headlights on and use the "flash-to-pass" feature.

okay i got you so the 2 fillments, one lights for low beam and then swiths to the other for high beam.

i think they both go on, cuz my one headlight is out, so i drive w/ the high beams on, and they both work, but the light that is out, is not nearly as bright as the other one, so i figured that only the high beam was on in the burn headlight, and the headlight and highbeam fil were both on in the other owne- just some input

nope, only one at a time. is there a way to rig it so that you dont have to hold the "flash-to-pass" (meaning by turning on the brights will turn both on)?

I suppose you could setup a relay to turn them on, but I don't think the housings or the bulbs are designed for the heat or electricity draw. Probably about 110 watts per bulb compared to 45 or so.

My thoughts exactly! Way back when i was going to wire the lows to remain on when highs were selected, but I did not for the very reasons Adam mentioned.

My driving lights are brighter than my headlights.

they are usually 50/60 for low/high beams. i think it can handle it just fine as i hold the bright switch in that position all the time goin down old country roads.

I thought they were 45/65 stock.

If it was designed to handle it, that is how it would have come. engineers did not assume people would be willing or able to hold the stalk while driving for hours on end. As for thinking that stuff is engineered perfectly, I wont bring up that they could not even create a fog light circuit that would not overload.

But by all means, try out your idea and post back how it works.

haha. Well, its actually pretty easy to hold and drive for long periods of time. And i really do doubt ford's electrical engineering skills back then. I have an aftermarket CD player and 6.5" pioneer speakers in the door and 6x8" Alpines in the back w/ stock 3.5 in the dash...i can see the faceplate dim and the voltometer drop everytime a lil bass hits. And my bass is only set to +3/6 and SLA at +2/4 and volume at 12/35.

The charging system was never really upgraded (till 94) for a fuel injected motor (fuel pump, computer, etc are all decent sized draws).

might be 3G time for ya. (or some capacitors).
