Have just been upgrading all the interior lights to LEDs on my mates 2006 pre-facelift TDV6 and all 3 of his boot lights have stopped working at once.

All other interior lights are fine as are the number plate lights etc.

A fuse would be the most obvious thing to me, but I can't see one listed for boot lights - there's one for "Interior lights and windscreen wash" but they're all working fine.

Any ideas?  Past (too many to list, but a few favs)...

Turn the bulbs that aren't lit thro 180 degrees in their holders.
They're polarity sensitive.

Thanks for trying to help.

I wish it was that. I know the bulbs are polarity sensitive and we even checked all the lights again with the original standard bulbs and no joy.

One minute they were working (we'd fitted one of the three with the new LEDs), the next all three of the boot lights stopped working no matter what bulbs we tried - hence why a fuse would make sense.

All the other lights, interior and exterior are all working fine.

Still stumped.... Past (too many to list, but a few favs)...

Fuses 17 or 27 then.

Thanks. Will ask him to try those... Past (too many to list, but a few favs)...
