Hi guys, I have a question about the lights on these trailers. My lights work but no blinker or brake light. I read some people said to check the ground and that looks solid so I figured I would see how the bulbs looked. There are 2 bulbs in the light fixture one normal light with 2 elements and then another smaller light on the outside edges of the light housing. Mine looked black when I took it out, not sure if this is normal. Big issue is I stuck it in my pocket so I could try and match it with something, but I appear to have lost it. Does anyone know what that does and where I could find another one?
