So im installing a set of spyder led headlights. The led light is powered off of my marker lights. Before, when i had my oem headlights in, the left marker light would work and the right was out. Now, the right side led is working (powered off of marker light) and the left side is showing nothing but the orange turn signal and very dim low beam. Im thinking it could be a fuse of some sort but cannot find anything showing how the marker lights are powered. Thanks in advance for any help

 

So mine was doing the exact same things. I disconnected the battery and discovered the terminal was loose. Figured I would completely disconnect to check alternator. Alternator is going bad apparently and started cutting out. I properly connected the battery and everything working except side markers. Turns out if alternator isn't pushing enough power the side markers don't come on.
