Q: Really weird brake light activity

asked by on February 01, 2017

Ok so I was working on a freinds car and she informs me that her brake lights don't work. So I got to inspecting it looking for the issue. Well her brake lights and running lights are the exact same bulb but with 2 coils. Both coils were in tact, there are no blown fuses and I figure the wiring is fine cause the running light coils still work in both lights. Now I know about the hole brake switch issue but here is the kicker, there is a third brake light on her tail fin and that one works like it should. So any suggestions
