Wiring Question

[GeneralTso]

So I have a a question about ground. I'm trying to wire up the front turn signals and I have the hot for left and right but no ground wire from what I can tell. My question is can I ground the turn signals to the same ground as the headlight or is that going to cause problems?

I've been looking but can't see any ground that was dedicated for the turn signals. The headlight ground works on the bench but I don't know if it would cause problems.

Thanks guys
