headlight upgrade

[HPP]

Sealed beam filament lights are what these cars came with. The filament required a vacuum to operate and the filament was susceptible to vibration damage. These were universally used until the late '70s when halogen  lights came out and by the '80s they had became more common. However, vehicles designers were still using the same dual/quad round/square configurations in most designs, so sealed beam halogens were the norm. These were a glass light like the sealed beam, but they had a sealed halogen bulb inside of them. In the 90s designs for headlights made a big step forward into custom shapes made of plastic with reflective surface and a removable halogen bulbs. We had moved into the realm of replacing headlight bulbs instead of whole headlights. As technology advanced, H4 series bulbs become the norm for use in everything but we still had reflectors. As LED technology advanced in the '00s, it got to the point they could now be used for headlights and we lost the need to design around reflectors. This is why new cars have such unique headlight designs.  It also means you can concentrate all this light into a single point bulb for retrofitting into a sealed beam style of projector, which can be put into our classics.

A sealed beam could be Halogen or not.
The H1 and H4 headlamps have replaceable bulbs, a sealed beam is sealed and the bulbs are not replaceable.
I installed a relay kit and Hella H1/H4 lights...I do need to properly aim them but they are MUCH better than any sealed beam I've ever used.

My headlights came from Summit Racing. The H1 are high beam only and the H4s are the high and low.
For relays, I bought a plug and play harness from a guy that is on FABO. FBBO and Moparts under the name "CrackedBack". Mine was $180.

Kern Dog,
Do you know if "Crackedback" is still selling the harnesses?  I'm interested in buying one, am not a member on the other forums and don't really want to join just to try to send him a message.

Thanks!

[Kern Dog]

Yes, he is still doing the relay kits. I have no contact information other than through the forums.
Good luck.

Honestly and I don't want to screw up the bussines to anyone, but crackedback harness is an easy to make job at home. Not a lot of skills required, but getting the propper parts, which are available around.

And in fact, can be done even better. Like I did without cut a wire too and even cleaner.

As far I guess, crackedback harness would make to keep original HL plugs hanging around (but just one being used as trigger for the relays) and run a parallel HL path along the original at radiator core support. Right KD?

I have my relays hidded down The kick panel, and taking the power from amm stud (sure I have a parallel path between alt and amm), still using original paths. Nothing extra added visible.

Just need to make two jumper wires (8-10 inches long) one red, one violet with packard terminals on both ends, ground wire from anywhere around (I used the foot switch screw for ground source, so another 8-10 inches black wire) and take the positive from alt... so the lenght accordingly to that... IF alt bulkhead path is already upgraded, reach the amm will be enough.

Then of course the relays and plugs

Breaker or in line fuse adviced of course for the positive source.

I also made up my own kit for my 69 Charger
The factory wire harness had a join in it right beside the battery so I took it apart there with the idea if the relay failed I could still just plug the harness back together to see where I was going
Took out one fender bolt and made a bracket with a hole in it to go under the bolt for the relays to fasten to
Was always going to move it up in front of the rad support area but never got around to it
Worked like a charm and night and day difference in how bright the head lights were

Amazon sells a relay a kit that plugs into an original high and low beam plug and connects to the battery.  I did also have to make a relay setup to replace the door switch on my 70.  There was extra voltage going through enough to mess up the new relays

eBay has them too, this is an example.

eBay has them too, this is an example.

That's cheap as.
Why would you even bother to make one yourself at that price?
