I'm a bit stuck with my Fiesta. When I have the lights on, the brake light on the passenger side isn't lighting up.
I changed the bulb today, and with the cover off, when I hit the pedal it does get brighter but not very much.
With the cover on its barely noticable so when its dark and the rear lights are on it looks like the brake light is out completely.
Its trying to light up but not really working. I'm using a Lucas 380 dual filament bulb 12V 21W which looks right. This is a newish problem that I only noticed a couple of weeks ago.
I've checked a couple of bulbs and a couple of fuses. Any idea what else might be causing it?
I doubt its the brake switch as its only one of them.
In the meantime I am going to try and sort the top brake light so I at least have 2. Thats a problem in itself!
