2 or 4 PIAA 520s

[BGA23]

I'm planning on installing at least 2 PIAA 520s on my brushguard. My question is would 4 provide an additional benefit? Or is it more a matter of overkill in that 4 lights don't provide much additional light over 2? Of course, this doesn't take into account the fact that 4 looks cooler than 2.

Depends on what kind of light you're looking for. Personally, I'd go with 2 of them in the driving light configuration. Pencil beams are too tight and fogs don't throw light far enough. You might also consider the 525s.

I think 2 would do the job.

What is the difference on the 2 lights, 520's or 525's??
