Technical technical headlights and turn signals

first some info about truck:

1941 ford p/u
universal speedway headlight switch
universal speedway dimmer switch
signalstat turn signals
Now the problems all of the components above are at least 10 yrs old
This morning as I was driving to my normal
geezers breakfast I noticed the bright light ind and l/s indicator were dimmly lit turn off lights and t/s worked as they should replaced h/l and turn sig bulb still no change. where shoul I look next thanx in advance Tom

 

Maybe it's just me, but when bulbs are dimming I think alternator issues?

By the way... if t/s is turn signals, h/l is high low... l/s...I'm stumped?

 

What were the dash/gauge lights doing?

Sounds like a ground problem somewhere; but high beam ind glow along with the signal ind glow make me think of dash ground problem of some sort.

 

l/s = left side
h/l = headlight
t/s = turn signal

is my decoding...might be wrong...

but yeah, make sure the dash ***embly is grounded properly. Lack of ground on light circuits is the usual culprit when bulbs are glowing faintly.

 

I would be checking the grounds for all the lamps at the front of the vehicle. Park and signal lamps as well as headlight grounds.

 

Cl***ic ground issue problem. Go out and see which bulb isn't lit or very dim.

 

thanks guys I kind of suspected it was the grounds,but being 74 getting up down from the driveway is not as as easy as it used to be. But long story short spent about an hour yesterday shining and tightening all my grounds every thing working now. Thanx again Tom
