Sorry to hear about your accident. You will be able to have it resolved quickly with his insurance picking up the tab, as long as he's insured. But make sure that he's insured, otherwise, you're on the hook for the deductible if your insurance can't get the other one to cover it.

Also, next time, take a photo of him when he's not aware, so no hand in the lenses.
If you need a pair of tail lights, we have 4 sets of LCI ones from Europe in stock.
