Great product, Bright!!!, great customer support. Many on this site have installed them over the years. I can’t say enough good things about his customer service,
call, write , or send a PM to Thomas Duncan the owner. @thomas@vintagecarleds.com
He knows our site, and our cars. I have his bulbs on my speedster since 2015, my ‘79 vespa since 2017, and a couple other cars.
he sells both the bulbs only, of bulb headlight kit. Limited Lifetime warranty.
