For sure, the reflective quality on the modern car headlights is way beyond what we are used to in a 60's vehicle. Also the demand to manufacture a light for so few vehicles hurts the product we are in search of.....
I thought of LED's for my 66 Biscayne, but after researching Chevy websites and Lighting sites, it was 60-70% in favour of HID's. I've had all the "latest" super lights in my vehicles and found these HID's to give the best light structure down the road.

Newer bulbs may not solve the problem.

Lights are often dim due a large voltage drop; designed to operate at 14v. Actual voltage at the bulbs is often under 12v.

Solution is to run power direct to the lamps via relay.

I agree with William on this. I put a relay on one of my Chevelle's and it made a big difference in the brightness. I was thinking it was a kit from someone. I may still have the box somewhere...

Yes, That's the place.

Yes, I did install relays too. One for each set of lights, high/low.
