One of my break lights is out, so bought a new bulb from fords, didnt solve it ok went n got another still didnt do it , all the other lights in the bulb holder that you put into the rear light work, my guess is that the bit you put the bulb into is knackered ?

my question is if i went to a scrappy to a 2.0 sierra or something and took out that plate bit that you put the bulbs into will it work in the cossie ok ?

or does it specifically have to be a cossie one
