Guys, When I turn on my headlights but of the signal lights work fine. When I make a right signal that one works fine but when I signal legt with the driver side signal it does not work. Obviously the bulb is fine, what to do next?

 

Let me see if I got this straight.. "your drivers side turn signal doesn't work when you try to signal left?" If so, just replace the bulb (#1157).

 

It is a dual filament so that means half the bulb is working. The part to signal is burnt. Just replace the bulb. I've had it happen to me before as well. When they are not blinking they are fine.

 

I have the exact opposite problem. When I turn on the headlights, the driver side signal light is completely off (no yellow light), but comes on if it is blinking. Does this mean that the other part of the bulb (not for signaling) is burnt? thanks

 

Yes.
