LED Front Turnsignal And Rear Brake/Taillight/Turnsignals Options

[morgan_harwell]

Looks good Cary. Are you using the stock 914 flasher or EP36 or other?
A couple of notes:
. . .

2) The early stock 914 flasher (with L & R dash indicators) seems to work fine if the dash indicators are rewired so the common wire normally from the K lug on the flasher are connected to ground. This little bit of resistive load seems to cause the flasher to flash normally with LEDs front and rear. My 914 is wired this way and the flasher will flash normally even with both front and rear lights removed. Another 914World member with LEDs front and rear got his early flasher to work only after rewiring the dash indicators.

3) I'm adding a 1k ohm resistor across the turnsignal wires on the front and rear boards to add at least a little bit of resistive signature to help flashers see the LED loads. Not sure how much this helps but it's easy to do.

. . .

Howdy,

Is a symptom of the above problem => all four LED Turn Signal boards flashing together when the steering column turn signal stalk is set to Left turn or Right turn?

edit 8/18/2016:
I re-wired the L & R dash indicators in the tachometer per 2) above, and all four LED Turn Signal boards (front & rear, left & right) stopped flashing together. Now they operate as expected.

All 4 shouldn't operate with the left or right turn signal on. The light loads that these LED boards present to the wiring has a way of illuminating deficiencies in the wiring. Anything is possible with these old cars.

Jerry;
Have you thought about getting these certified for road use? Saw a post on another forum from a guy in the industry saying that a test for certification could be as low as $500. Is there enough volume to justify that?

I haven't considered getting these certified mainly because of the low volumes. Also there are many variants which I imagine would need individual certification:

914 brakes;
914 rear red turnsignals;
914 rear amber turnsignals;
914 front Euro White/amber;
914 front USA all amber;
911 brakes;
911 3rd brake;
911 rear red turnsignals;
911 rear amber turnsignals;
911 front Euro white/amber;
911 front US all amber

We're gearing up to do another run of front and rear LEDs. Should have PCBs in hand within a month.

Making some small changes to the boards before going to fab. Every board will now have a footprint for a ballast resistor. This will help dampen the effect of any leakages or other circuits on the light wires.

We're just clearing up an interaction issue with 911 brake lights where the cruise control brake light sensor dumps about 8ma into the brake lights. With no ballast resistor, the CC sensor pulls up on the brake light wire until the LEDs turn on a little bit and the CC refuses to stay engaged. We're adding ballast resistors to all boards now.

What is your configuration for Euro tail lights side marker?
In Europe, my understanding is that they don't use the side marker bulb.
Here, with the small bulb on the side the amber part of the lens gets lit which makes a combination of read and amber taillight. I have been looking for a red small bulb to put on the side so that the amber part would become red.
I found some red covers at Autozone and it worked for a while until they crumbled from the heat.
The result was red everywhere then when the blinker would kick in, it would flash amber.
Did you ever try something like this using LEDs?

I would be in for a pair rears. Have your front Euro's (IMG:style_emoticons/default/smile.gif)

PM'd you a month or 2 ago.

Still in !

[rgolia]

I am in for a pair of rears US spec. When I purchased the front from you, you mentioned that the rears can have a dim light in the brake light area.....if still possible put me in for that. Thanks Jerry and my fronts look great.

[Shadowfax]

Very pleased with the rear lights. I'm in for a pair of U.S. front LEDs.

Well, I'll just throw this out here... No affiliation to me, just ran across it while looking into the legal aspects of aftermarket lights. From some other thread it looked like you had some pretty thorough testing abilities, this shows what the official tests are looking for with maxes and mins:

This whole thread is good from a technical information standpoint- one of the linked threads is an all out flame war and OK for entertainment.

That is a good thread. Lots of good information. Thanks.

Sent the rear PCB design to the fab this week. Will have rear PCBs in about 2 weeks. We'll start with the rear lights then add the front turnsignal bucket lights in the next months. I'll start a new thread when the rear lights are available.

[SKL1]

Need rear brake and red turn lights for a '73 from your new run...

thx Spoke...

Jerry, are the 'old' ckt boards capable of this mod (adding ballast resistors)?

If so, can you post a pic of where to add the resistor(s), and the value needed?


Paying 'OHMage' to you for bringing these to the marketplace (IMG:style_emoticons/default/pray.gif)

[Coondog]

Put me down for

1 pair euro fronts with blanking

1 pair euro rear turn amber

1 pair red brake light

[LowBridge]

wow...

please put me down for a pair of front US and a pair of Brakes US.

also do you make a backup light kit?

do you have a timeline for delivery?

[JoeD]

I'm in for a full set front and back...

1 pair euro fronts with blanking

1 pair euro rear turn amber

1 pair red brake light

Thanks!

We had been adding 1k ohm ballast resistors to all front and rear turnsignal boards. These are not the 6 ohm power ballast resistors which can be purchased from lighting sites.

The 1k ohm resistors only help an LED-compatible flasher to break over and turn on.

After the 911 cruise control work, we're now using 301 ohm ballast resistors.

Do you have issues where a ballast resistor would help?

Don't know - I haven't installed them yet ... many other tasks to perform (on my wife's '71) before I get to these. I'll see if I can find some [spare] time to try them out, and report back.

I installed the euro ones front and rear. The fronts have the blanking circuits. They work great and the light output is night and day better. My flasher relay works fine, but the dash light stopped flashing. At this point I do not know if it's related to the led lights. I have done a lot rewiring with the new gauges. Hopefully I will have time to play with it this weekend.
