Hi ive only just joined as ive just bought my first ford :) fiesta st and have a slight problem that i was wondering if someone could help with please, when i purchased the car the top and drivers break light wernt working, so i replaced the bulbs and now when i break the top one works fine but when the break peddle is applied the drivers break light just cuts out the drivers rear light, hope that makes sence
so i was just wondering if anyone has had this problem before and what they did

Thanks for any help in advance
