installing turn signals on 1941 using LEDs. anyone?

anyone have any experience with using LEDs on a 6v positive ground 1941 ford as turn signals?

i'm in the middle of doing it and getting some strange results.
 
If you are using LEDs for and aft, you need a flasher designed for LEDs as the load usually will not trip a conventional flasher.
 
thanks,

i've got a solid state 6v positive ground flasher. it makes very little noise when flashing, which is a problem, as i need to hear it click. i don't want to be "that guy" that's driving around all day with his turn signal on. and i will unless i can year it click. ya know?
 
You can buy a low voltage DC piezo. Typically work on 3V DC to 24V DC. You connect it to the pilot terminal on the flasher unit. Just be careful of the volume as some are up to 90dB. I have one connected to an oil pressure sender.
You could also try Pick a Part and get an audible alarm from a modern car. They will probably work on 6V. I'm not sure if they are polarity sensitive, but just put the positive side to the frame.

thanks for commenting...

so you recommend something less than 90db? i have a convertible and the aural clicker on the ledlights.com flasher that i have is absolutely pathetic! i have to question why they even include it. smh
 
I use a piezo on my car. I taped a cotton ball to it to reduce the noise. You can customize the noise level with more/less insulation.

are such things as a piezo buzzers available anywhere but online these days? i couldn't find one in the East Bay area unless i drove about 40 miles to MicroCenter in San Jose. hmmmph!...no more Frys or RadioShacks.

and i need a 6v diode to wire inline with my REAR (yes, Martha i said rear) two connector LEDs to prevent a power feedback situation to the FRONT one connector LEDs when turning.

the way it's working now is, if headlights/taillights are one, the front turn signals don't turn off and on, but rather express themselves with a dim/bright, dim/bright cycle. ...go figure, eh?
 
Snyders carries 6-volt beepers. There loud and I took a piece of sponge and taped it to the beeper for just right loudness that I wanted.
 
I used one of those also, I wrapped black electrical tape around it until I got the volume I needed, just enough to hear it above the Red’s headers.

^^X2. This is the same style I installed in the Model A with just enough tape to reduce volume to suit.
 
yep! that's the same buzzer i bought!

i plan on installing a female spade connector to the "P" terminal on the flasher that will have two male spade connectors on it. IOW a splitter. so that i can drive the buzzer with flashing current from the flasher's "P" terminal that powers the flashing bulb on the stalk. and because most of the piezo solid state buzzers i have seen have a black and a red pigtail, and assuming that the black one is meant to be connected to ground, i will have to connect the red one to ground on my positively grounded ford. and the black one to the splitter.

does that sound reasonable?
 
I did it with my 42 converted to 12v .. had to use a heavy duty flasher as the led one flashed way to quickly. I am however using regular incandescent buld for teh front turn bulbs (mounted in the original marker light housings

Correct! If you are running 6 volt positive ground, black wire to the P terminal, red wire to ground.

$6.29 on Amazon and I can have it Wednesday.

There also good as reminders you left something on like headlights, add a relay and it’s a fairly simple circuit.

yep, that's the one, i've just been informed by Amazon via e-mail that i will be receiving it today!

and thanks for the tip...but removing the old turn signal system that was not suitable for use with LEDs and installing a new one that is, has taxed my 'inner electrical engineer' knowledge and ambition to its limit. :)

and there's a wire or two yet to run, so i've got a couple more forays to endure under the car. the good news is that the original ride height is so high that i can get under it without the use of a jack, which is a godsend.
