You can buy round Halogen sealed beam headlamps anywhere. I got mine from O'Reilly. Obviously not as bright as HID, but they are plug n play.

If they're brighter than what I have, I'll take it...

 

[71RR4406]

I am just finishing up my 71 Plymouth RR wiring.

I have installed full LED with DRL and Amber Turn. I picked them up on E-Bay for less than 100 with shipping. The ones I purchased only needed a small nob on the back taken off. No mods to the buckets or original wiring.
It took me a bit to figure this all out and get everything working properly.

I have the DRL set for Running power.
When the Turn signal or Hazards are enabled, the DRL will turn off and then flash amber. Upon turning off flasher, DRL resumes.

When Parking Lights are turned on the White DRL will turn off.
The blinkers and flashers work the same as above. The amber parking lights will turn off and then flash.Upon turning off flasher, DRL resumes

When the headlights are turned on the parking light will disable and the DRL will resume. When the Turn signal or Hazards are enabled, the DRL will turn off and then flash amber. Upon turning off flasher, DRL resumes.
Headlights will stay on during the Turn signal at night.

I am in NJ, this is legal, and can not see why it is not legal in any state. I have them working basically the same as my 2022 Dodge Durango.

My next step is to potentially add two more relays to have the front marker lights flash on turn as well.

I have also changed every bulb in the car to LED.

I will post some final pictures once it is back together.



There is one caveat when activating the High Beams, but you can insert an optional relay to take care of that.
Parts list below.

FYI make sure you change your Flashers to No Load Flashers compatible with LED.

I may convert the Marker lights to Flashers as well for looks and safety.

I will post another design with the two additional flashers when i have some time to get back to the garage.

You will need seven (7) standard change over relays, 5 pin Bosch style and two 2 (2) delay off 5 pin Bosch style.
