Where can I buy a replacement headlight?

The bike is a 1980 suzuki gn400. It has the stock headlight assembly on it so I'm looking for a headlight that will fit it. It's a 5.5" diameter bulb. I've been looking for weeks and haven't been able to find anything. Thanks for your help. (Oh also, there are no dealerships anywhere near me.) via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/ar4sq9/where_can_i_buy_a_replacement_headlight/?utm_source=ifttt
