Yikes! Those are even oversized for HO! I buy my streetlights from an eBay seller from China called "wehonest_us" - they sell LED streetlights in various scales, including N, and the prices are excellent (resistors included too!). Many N scalers, including myself are thrilled with them.
Reanimating an old zombie thread... Thanks Metro, for the tip about wehonest_us on eBay. I went through his N scale offerings and picked up a couple sets of streetlamps for a very reasonable price. It'll take a while to get here (definitely *not* Amazon Prime speed) but that's ok.
