OBC keeps showing parklight error
 

So for the past week my OBC has been going off on a park light error. The first few times it was the left hand side, but everytime as I shut the hood, the parklight went right to work (I didn't even touch anything).

Today, however, was the right hand side's park light that went out. I played with it a bit, couldn't get it to work. You guys know how if the park lights go out, the turn signals light up instead? I decided to take out both park lights so the turn signals become my park lights. Is this a wise thing to do? Or am I damaging something here?

TIA
EDIT: I hope you guys know what I'm talking about cuz it seems US Spec E53s don't have park lights.
