Hi all,

Firstly huge thanks to you all on this forum both new threads and old. I have had my first full fat for 3 months now, having previously had a Velar (nightmare ordeal, but thats a story for another day...).

Anyway, I thought I'd start tinkering with the LED bulbs. Interior and number plate bulbs were easy and work great.

Today I moved onto the rear indicator and fog/running light bulbs which are incandescent. Note I have the S/C '07 L322. This thread was a great help https://www.fullfatrr.com/forum/topic70881.html but I had to do the indicators alone as couldn't find much info on REAR indicator LED upgrades.

Issues I need help with (probably paging @stan here...!).

1. Check rear bulb error. I haven't got IID but I'm wondering if by disabling hot/cold monitoring this will help. If not, does anyone have any bulb suggestions (the thread linked above all have dead links so can't find what was suggested)?

2. Indicators look GREAT but the first time indicating on startup they blink rapidly for 5 times, then operate as normal. Can this all be fixed with disabling the monitoring? Note the rest of the indicators on the car are standard, I'm going step by step to avoid complicating things.

3. Puddle lights in the door mirrors. Installed a "ready made" kit for the L322, so should theoretically have resistors etc. inbuilt. However on unlock the left one does not activate at all, the right one blinks briefly then dies. Using the original bulbs, the same thing happens. Does this perhaps mean the left wing mirror wiring is dead rather than a bulb issue?

Thoughts and help appreciated, and thanks again everyone for your help past and future! L322 2007 S/C 4.2L

I believe that the car checks bulbs when ignition is turned on, hence the pulses you are seeing initially. Disabling checks will stop that but obviously you won’t know if a bulb has failed without looking yourself.

You might be able to get canbus friendly bulbs which are made to not have any of those issues. I’ve never changed any others so can’t help there I’m afraid.

this may help you ?
On my recently purchased 2007 3.6 Tdv8 both puddle lights did not work, so I bought the LED items from Powerful UK ( Just for info - I am not connected to the company in any way )
I fitted the drivers side first, on testing when unlocking the lamp flashed once and went out, so the next step was to fit the passenger side LED to see what happened, upon removing the old bulb from that side I found a build up of products from corrosion etc, cleaned the contacts up nicely then fitted the second unit and bingo, both work properly, luckily a simple easy fix, hope this helps

RE the puddle lights.
+1 for corrosion on the passenger side.
Cleaned as much as I could with a carburetor brush and contact cleaner and now working great. ---------------------------------

This has been posted elsewhere but mentioning here in case someone else sees for the approach lights (wing mirror) LEDs.

Ended up buying a splicer on Amazon for the wire and wiring the existing bulb in parallel on one side using a soldering iron (badly). Does work though!

powerfulUK put this down to all the interior lights being changed to LED, which Im not sure is correct!

RE check rear light - swapped to some other bulbs and these don't throw an error, so its trial and error really!

RE indicators...waiting on some new bulbs to try! L322 2007 S/C 4.2L

Multiple different indicator bulbs front and back replaced and they still hyper flash x5 on start up (only when triggered). After that they are fine, perhaps a tad faster than original but the trade off is worth it. Once I have budget for an IID I'll see if that helps. As it stands just the H7 main beam to replace now.

I got some from Amazon but they were weirdly very dim...trying some others this week. L322 2007 S/C 4.2L
