LED Front Turnsignal And Rear Brake/Taillight/Turnsignals Options

[mbseto]

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 !

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.

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.

Have the euro fronts on the '73 and love how they work with the top blinker and bottom running lights. SO much better than those cheap "kits" to make the euro lenses work appropriately.
Rear euro lights with brake lights also work great with much better output than stock on my '71.
Just need the US rear sets for the '73 when Spoke starts his new run. Didn't order them in time with his last run...

You have a single L/R dash indicator, correct?

Your stock flasher still flashes with LED turnsignals because the flasher does a dual purpose: Flash the turnsignals and flash the brake indicator.

See the diagram below for 74+ 914's with the single turnsignal dash indicator. Notice the coil and relay contacts next to the 49A and C pins on the flasher. This secondary relay allows the brake indicator to flash the small, low current bulb in the dash without flashing the L/R indicator.

When the very heavy load turnsignal bulbs are connected when either the turnsignal stalk is active or the 4-way flasher pulled, this secondary relay will close and flash the L/R indicator. With LED turnsignals which are a very light load are active, there is not enough current to pull in the secondary relay and the L/R indicator does not flash.

Question: does the L/R indicator flash when the 4-way flasher.

There's not a plug-in replacement for this flasher with the secondary relay. Thank Porsche for that little feature. There is an EP26 flasher available with 4 pins like the original. Unfortunately the K/C/C2 pin on EP26 is not connected to anything. I did modify an EP26 to power the K/C/C2 pin for one guy.

Personally I'm not a fan of the single L/R indicator. I think it's stupid. On my '74 914, I purchased an early tach, removed the guts and installed the guts from my '74. This way I had dedicated L and R indicators.
