Hi, I have a 2003 350Z and I'm experiencing something that seems weird to me. It might be just the fact that my bulbs are dead but I want to make sure.

When I just turn my lights on, both taillights work but when I brake, only the driver side one gets brighter. The same thing is happening with the front headlights. The drive side is working properly but the right one the little Day Time Running Light bulb doesn't turn on. The main light works though. I'm wondering if it's just the bulbs or it's one of the fuses.

Thanks!
