OSS does not offer wholesale solutions. Only direct. Another great option is BayOptik.... I think their quality is far superior to OSS. The OSS are a bit messy....
Check their instagram. We recently shipped a set of headlights to them and we are expecting our customer's headlights to return to us next week. Will post some pics once they're installed:
