Voltage for Vantage Headlight LEDs?

[pikajew]

I know it's a long shot, but does anyone know (or can get) what the voltage is from the vehicle (vantage) to the headlights so we can test the headlight LED circuit board?

You want to know the native voltage of the LED components?

[pikajew]

Yes, that would be most helpful. Someone just replied on another forum that it is 12V. Is that correct?

Surely, if you're going to dismantle the headlight you must have access to the headlight connector. Why don't you just stick a voltmeter on that?

The driver board is supplied with 12v but each LED is 1.8-2.4v.

Beautiful. Thank you VERY MUCH.

Actually I'm out of the US on vacation and my body shop is having difficulty getting my headlights to work. I've had them modified by Oracle for my build (ADDING red LEDs but keeping OEM lights as well) and although they swear they never touched the OEM LEDs or connector, the RT headlight has the white LEDs working but not the Amber blinker, and the LT headlight has neither white or Amber working. I did get new carbon edition tails too (from AMBits) and I've heard sometimes these issues can be caused by the taillights... Regardless, my shop is sending the lights back to Oracle, but they have asked for the voltages so they don't fry the circuitboard.


FYI, if you're interested, my build is here: http://www.6speedonline.com/forums/aston-martin/39...

When they did the LED work, did they add switchback to inhibit the other colours while your 'blinker' is in operation?

What on earth possessed you to mess with the OEM lights? Of all the components on the car to leave well alone if working OK, that's the top of the list

No because they added red LEDs in the same area as the white OEM ones (but will be on s separate switch).

Have you seen the thread on my build?? Lol

OK, it was a long shot.

[pikajew]

Was a pretty creative thought! I know it's a longshot, but I'm going to check the connectors to the taillights to make sure they're not loose as I had carbon additional ones installed. I've heard that sometimes defective taillights can affect the white/Amber LEDs in the headlight.

I take it they have done the basic and put a temporary earth to the headlight assembly, poor earths anywhere on a car can cause some very random things to occur.

So I had a hunch that the taillights had something to do with it and my shop (who had installed the new carbon edition clears but apparently never tested them) just verified neither of the tails have the blinkers working.

I'm not physically there as I'm on vacation. Does anyone know if there is a special way to connect them or why the blinkers on either side don't work?

Have you swapped the rear lights from red to clear? Early cars needed a re-flash by AM to get them to work

So it's a 2008 but... I already had clear lenses installed previously (with the light gray surround). Do you think it would need a re-flash from a swap from clear (gray) to clear (carbon black)?

Not done that myself, but wouldn't surprise me. MAy be worth giving your local / nearest AM servicing dept a ring.

[pikajew]

Called dealer. They say it should just be plug and play! Grrrzzz

[pikajew]

I forgot to mention that most of my modules (a/c, switch plates, radio screen, nav screen, clock, and other buttons like hazard, window defogger, etc.) are still unplugged pending the carbon fiber consoles.... Consequently, the gauge cluster is blank and non-functioning. Perhaps it's screwing with the circuitry or the car's voltage and causing the blinker issue?
