Be wary, the image above is for a Volt tail light (Ampera does not have the black band, same with the units on the tailgate so importing from the States might not be easy. Also, I think that early Volts had the red indicator and not amber so if the car was braking with an indicator on one side would be solid red and the other would flash as the indicator.
Yes - a good warning there
@h8ten. The US light units will be no use here.
Something just clicked in my memory and I looked through the old invoices that came with the car and found this, which seems to suggest they have been changed on mine last year before I got it and, compared to the US catalogue price above, the price from Vauxhall to change both , including labour looks quite reasonable . Although I'm not absolutely sure that these are the same things - they do have a 'V' part number - but I suppose could just be the numberplate lamps haha. I have to say though that in the recent cold weather, the condensation has made an appearance again.
btw the offer to fix the door handle for £400 was declined in favour of
@HandyAndy 's excellent value alternative.
