Hello,
Im new here, i own mazda 323f bg from 1991 year. I want to buy a spoiler with third brake light, and i have a few question about this spoiler and the stop light.
How this brake light is installed in this spoiler, what kind of bulb is installed there, how to replace this bulb. And how is it worth in your countries.
Thanks for answers

I believe it's with led's.
You have to get the unit out open it and unsolder the bad ones and solder new(if they are the problem)
Wish you luck!

This body-coloured double spoiler was standard only on the GT facelift BG model from about May 1991.
….
although I don't remember the UK models having a light in them!

Yes, they have double spoiler with 3rd brake light.... BUT.... Only in Japan, and east of Asia, if I remember Australia, New Zeland have them too.
There exist spoilers: Double with 3rd b. light, oridanry with 3rd b. light, double Euons 100 etc...
