LED bulbs in the tail lights, 70 Charger

[Beach Goat]

I'd like to reduce the draw on my electrical system. I've been slowly replacing bulbs with LED replacements, so far I have a few of the interior bulbs and the license plate bulb, and I'm working on the reverse bulbs. Next I'd like to replace the tail light bulbs.

The 6 tail light bulbs are also the brake lights and the turn signals, correct? So I'll only have to replace 6 total bulbs. My main question is, is there a specific relay just for the turn signal? They make a relay with a built in adjuster for the reduced draw that should prevent the bulbs from blinking fast; that would be a hell of a lot easier than wiring in a resistor to accomplish that.

Thanks!

I also think there are 1157 bulbs (?) and maybe 1057 bulbs (?) that have the resistor already built in. I look at this on my Mustang & bought some cheap ones of flea-bay and THEN found out there was something about resistance/turn signals....like you're talking about.

I'm listening in on this post for sure.

You have to remove the mechanical flasher unit and replace it with an electronic one. If you get one from "SuperBrightLED's" it's a direct fit. The ones that have an extra ground wire are a PITA and some what unreliable. For bulbs, they've come a long way with some out-putting 1000 lumens and plenty of light "spread" patterns. I have changed all of my bulbs but found the best price/quality on Amazon. Most, if not all, are made overseas and some actually have a warranty.

Thank you so much! So I need 6 total bulbs, right? And which flasher relay do I need? They have a bunch (on superbrightleds, that's where I've been getting them) and none say they fit the 70. Do you have a link?

Is this the relay I need? Just one of them?

Also does ‘goat’ need another flasher for 4-ways also? 68-9(?) has 2 flashers.

Remove and identify each flasher by it's pin count. Order accordingly. The flasher unit is the relay. When you buy bulbs do not purchase "polarized" bulbs as they are generally CANbus type that report back via an ECM if they are blown. You do not want "swichback" bulbs either as these incorporate two colors of SMD's, yellow and white. Get your brake bulbs in red, turn signals in yellow and backups in white . Look for the highest lumins you can purchase as your internal reflection surface and lense condition will benefit from the higher output. If you can't get red, white will work well provided your lenses are still good. "Oversized" bulbs generally fit without issue.

They won't actually flash at all with your old flasher they will just stay on like when you have a bulb burned out. Just replace your flashers and it will work right. Only thing is you will loose the tink-tink noise the flashers make. Also you need to check the polarity going into the LED flasher as they only work one way. Had to switch the wires around on both the turn signal and hazard flashers. I just used a small piece of wire and electrical connectors to jump them across.

no, all 6 bulbs are not brake/turning. 2 inner ones are just parking lights function... 4 outers are parking and blinkers

I bought a "No Load" flasher when I did mine

I did this on my 69. Here's some info (post #7)

These work fantastic and you can get them locally.

I bought an LED light kit for my '63 and had to switch flasher wires for the kit flasher that has the added ground wire. Problem is when trying the LED blinkers both go on at the same time (fronts only). The tail lights work as they should. When I put my original front turn signal bulbs back in they work fine. It was mentioned above that other wiring needs to be switched also? The outfit that sold me their kit hasn't ever come across this problem before. I have installed new engine and rear electrical harnesses and found the tail light sockets were crappy so re-installed the oem sockets as they were in good shape. Wish I could find a supplier that supplies quality bulb sockets.

I’m thinking of a dodo bird. 20yrs from now, nobody will know what an 1157,etc. bulb even is!!
