hello folks
i,m new here,and got an 07 v8v this summer, now the left front led turn signal is not working, the DRL'S and all other lights are working fine , is this led replaceable or the ballast ?? or does it mean a whole new headlight unit..
i would be gratefully thankfull for any info..ive read many posts on this and still not really sure

 

LED is not serviceable for the turn indicator. Unit replacement. Ballast is for the low beam HID only.

 

ok thanks for the reply, i noticed in the manual there is a DI resistor hooked
up to the turn signal , if this was blown would it cause the turn signal not to work,??

 

Did you ever find out what the problem was? Mine stopped working too.

 

hi troyboy
yes i did find out,, in my case with the car not being a daily driver
i had time to investigate, i took the headlight unit out. i opened it
up removing the lens cover carefully.it is a permenant seal but it
will come apart,this is the only way to get at the inner workings,
most times it is the circuit board underneath the led light strip that
fails,due to condesation,i am not in any way an electronic expert,just looking for any visible broken parts, i did bench tested the leds first,they were all ok.i found on the circuit board that one of the components had come loose from its base,probably due to vibration, (see pic of the new part inplace), with a little search and the number off the loose part (102) , i bought two just incase it happens again on the right turn signal,i also bought two of part (221) as they are the same type of part,just a different value..the 4 components cost $10 thats including shipping..i had no clue
what would happen when i put it all back together,but figured it was worth the effort,because of the cost of a new or used unit. (big bucks).
to my delight it worked,and i have had no problem since, call it luck if you will..ive added some pics lens cover removed -inner workings board location-new component soldered on board

 

Excellent, great job!

 

Great! So splitting the headlight open. You use a heat gun to soften up the glue?

 

Wow, fantastic job

 

Very interested in finding out how you got it open... using an oven or heatgun or something else... Thanks

 

There is a guy in California that has done a ton of custom work including an Aston Martin's and sealed headlights and taillights are in the special effects with LED lighting. I'm traveling now so I don't have access to his name but he's on my previous post I'm fixing clear taillights.

 

Take a cardboard packing box and place the headlight inside. make a round hole and put a hairdryer (no paintstripper gun!) in there and run it for around 10mins. That will loosen up the perma-seal and you'll be able to pull the headlamp apart. Done this on many cars and works like a charm.

 

in my case ,i didnt have to use heat at all to separate the lens from the unit,
after carefully prying the tabs on the lens i was able to pull it apart by hand,
with a little effort.it is possible that a previous owner had taken it apart before
.if that is the case, he did a good job, nothing broken or scratched..

 

Wow, great job, solutions, and reference to vendors. Another potential problem down the road that I won't need to worry too much about

 

Outstanding work Cadman! You are a gentleman and a scholar!

 

Hey many thanks as my left front turn signal is intermittent. This is something I will have to try on mine.


Had a rear turn signal go out but got a good deal from a person on here for a complete used light assy. I did get the old unit a apart and I'm looking for some info on the rear circuit board as I want to get it fixed as a spare.
