Trying to remember how these guys work. I see the four filaments, but don’t remember how each works. Parking, Break, Blinker

Anyone got this on the front of their mind, while I continue to search?
 
In the picture above, my tail lamp, has two bulbs w two filaments each. Which lights when? I am perhaps being restarted.

The guy doing the wiring, a fellow climber, (yes I have elicited help for a project that exceeds my abilities in a timely manner. For gods sake this has lasted 5+years, doing the electrical would take me another 5 years!) has asked me how they operate. I used to know but can’t remember.
 
Oooo
Those are some pretty lenses!!!! Envy
I have a pair that was on before that was all red and now I have a pair like the ones you showed w the orange.
One would imagine that only the outside bulb worked w the blinker and then the running lights and the brake lights would both work off the inside bulb. Right?

Right.

If you want spendy replacements

Or just red
 
Ooo lala!

I saw those during my quest for how the bulbs operated.

They currently aren’t in stock. I did send them my email. At least I could decided later. I image that 165 is for a pair….

The housing is clearly stamped.

USA 1073 on the left (turn)
1156 is electrically compatible
base: Ba15s (single contact/single filament)


USA 1034 on the right (tail/stop)
1157 is electrically equivalent (and will likely last longer)
Base: Ba15d (dual contact/dual filament) index base (axially offset pins, one direction only)


BA15 base is a Bayonet base with a diameter of 15mm (0.59in)

The letter after the base diameter represents the number of contacts on the bottom of the base:
  • D - double contact
  • S - Single contact
