Modern headlights and tail light bulbs for my 1974 Challenger

[rrbbkk]

Forgive if this has been covered before (I couldn't find it in search) but does anybody use modern LED(?) headlights and tail light bulbs in their classic Mopar? Are they as simple to install as just replacing the current head lights and tail lamps using the original wiring and sockets? Or is more involved? Upgrading the electrical system for example? Please, tell me all you can no matter how trivial. Thank you!

There was a post on FBBO about Octane 6K LED headlights.
The poster was pretty happy with them and had a link to the Octane website.
I took a look and thought they looked good and a reasonable price.

There are LED bubs available that will fit the existing sockets , be warned LED only work in one direction , if the bulb is made correctly it will work fine , you may need a different flasher unit as LED create far less load . I like them , the light faster are brighter & run cooler .
There are a lot of option for headlights , you can use Bosch or Cibie reflectors & install H4 bulb or there are purpose built lights , Holley offers some but they are expensive .

Hella H4 lamp housings fit 70 & 72-74 E-Bodies with two-headlamp systems and use H4 9003 LEDs. I am sure Hella makes housings for four-headlamp systems on the Challengers and 71 Barracudas, too.

The housing has a rubber boot on the back and it will need to be trimmed for the bulbs to fit properly. Ceramic headlight wiring harness extension sockets are plug-and-play and will handle the heat produced by the LED bulbs. You may want to choose a warmer color temperature to get a more original look but I went with the 6500K bulbs which are bright white.
The other lamps are in the last picture. Consider whether you want to install white LED bulbs in the housing even for the amber/red/green fixtures as some prefer to let the lense determine the color versus blending a color LED with a color lense. The LEDs are inexpensive enough to buy and try to tell what you like and you will have a lot of extras if you have Mopar buddies who want to get what you have leftover.

The Octane Lighting website has kits. This kit looks more original for lenses, too.

Check out the Holley retro-bright LEDs, pricey but they work very well and no cutting of the mounting buckets.
I installed these in my 70 RR, and fabricated Y connectors so I have (4) low or (4) high.....

Just my $0.02...

You will need a flasher that uses a ground for your hazzard/signel lights to work. Either use a flasher that has a ground pigtail or get a 3 prong flasher and install the ground wire to one of the prongs (easy to figure out which one is for the ground). I believe you need 2 flasher's

That has got to be one of the most screwed up sites to navigate that I've ever been on!
