My neighbor is converting his 65 Ford Galaxy to LED and they are bright, but when off, they are black.

I'll reiterate my previous comments: NO combination of lens, reflector and LED light source is legal for street use unless the COMBINATION was DOT compliant. Taking a HELLA CLEAR VISION body designed for a halogen bulb and using a LED 'bulb' is not DOT compliant and not legal for street use.
From
https://watsons-streetworks.com/product/led-headlights/ :
"These new 7” round Hella Vision Plus lenses use an advanced reflector design and conform to SAE/DOT standards for street and highway use." That may be entirely true - but only as long as they're used with the original bulbs for which they were designed and manufactured. As you can see at
My Hella Lights :: Vision Plus 7" Round Conversion Headlamp those assemblies are designed for halogen bulbs. Substituting a H4 LED for an H4 halogen renders that DOT compliance null and void.
From
https://blog.motoringassist.com/news...g-car-legally/ :
- "As halogen lamp optics are not designed to work with an LED bulb, some parts of the output pattern will be brighter and other parts will be dimmer. The other issue involves light scatter, which will dazzle oncoming motorists, which the driver may confuse as offering superior vision. Regardless of these technical issues, however, it still remains an offence to use LED conversion bulbs within an exterior lamp on the road."
- "I wish to incorporate LED lighting to my car’s exterior. How can I do this legally? The only way is to use a complete lamp unit that has been tested and wears a Type Approval Mark from an approved maker"
