Anyone actually do one of these conversions? I just put fresh bulbs in my car after one burned out and I'm REALLY concerned with the level of illumination we've become accustomed to with modern vehicles.
Classic Industries has a full LED board you swap in instead of an LED bulb replacement.
Kinda thinking about biting the bullet.
Thoughts? I saw a video of an install, they looked really good, but it was from one angle and in a garage. so...... dunno how I feel.

Here's the company that makes them. I sent them one of my 68 Dart tail light housings a couple years ago. Still waiting on them to get a kit tooled up for me. I was hoping it would be a plug and play type deal into the existing tail light harness but it looks like you have to run a dedicated power wire to the boards. Oh well, it will look cool and be lots safer so I'm not going to complain about a little extra wiring.

If you want to keep incandescent bulbs, these are the way to go. A lot brighter than the old bulbs, 43 candlepower vs 32. Genuine Honda 34906-SL0-A01 12V Bulb, here is a link on ebay.. https://www.ebay.com/itm/113935902916?

A lot cheaper on RockAuto too if you need to make an order.

RockAuto comes up as a Wagner Bulb instead of a Stanley?

It really depends on the lens configuration, as to how to convert our old lights to LED's.

I swapped all my bulbs with LED bulbs in both my '68 & '70 Mopars. I used LED bulbs from Superbright LED's. I picked "like" color LED's in each application ie, red LED's in red lens lights & yellow in amber lens lights etc. I love the results. I always use the bulbs with the most mini LED's on a given bulb, which really helps both brightness and diffusion.

The side markers really brightened up as did all the rest. Its much cheaper than some custom light insert too. I did have to change my flasher in both cars and add a resistor kit for my turn signals, but the carry all that at Superbright.

I have a set in my 68 Sport Satellite. They were in in when i bought it but I really like them. They are really bright. Mine are set on sequential right now i just havent taken them apart to change it to look like stock yet.

I'm putting these flashback LED bulbs on my Dart as well. Not sure if there is anything rectangular like these or if they are all round. These will work in anything that has a round lens.

It looks like the ones from Rockauto have a blue tint in the glass, not clear like the others. For the price though, I would give them a try. The candlepower shows both to be the same.

74 challenger I'm happy with these:

Rear replace1157 = https://www.amazon.com/gp/product/B01KLGRIR0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
For the rear inner lenses on a 74 they are just reverse lights. I sprayed the clear lens vht nightshade red and wired it to the outside lamp so they work together. Way brighter now.

Front replace 1157 = https://www.amazon.com/gp/product/B07FBZVYQY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1, these are also way brighter.

Well, got a set of the Honda bulbs on order. I'm a little concerned that the higher brightness may be warmer and "bad" for the lens, but either way, we'll do some science. I have some Hella bulbs I'm gonna swap in tonight for some before/after.

I replaced all the bulbs with LEDs in a non-Mopar classic. It made a big difference and no cutting wires. They make all different sizes, colors, and lumen output (brightness). More money didn't necessarily mean better. I tried expensive versus cheap LEDs from Amazon/ Ebay and didn't notice a difference. The only issue I had with replacing all the bulbs was a lack of resistance in the system. The turn signals didn't work until I installed a different flasher relay. I also installed an extra ground as I was experiencing a slight backfeed.
However, if you want the sequential tail lights, a LED replacement bulb won't give you that!

Note that OE style LED light panels from www.Digi-Tails.com have a Sequential Feature, simple slide switch on the PCB can be sequential or standard....

Just my $0.02...

68runner, let us know how they work out for you and any heat issues. I have them in my 69 but car is in shop still; won't be ready for at least 6 months for me to test them.

Attached are some pics. Left taillight is the Honda/Wagner bulb, right is a Sylvania Long Life.

Update 3! Got the big $$ LED bulbs in. Big difference.
Did a shot with the LEDs, and LED vs. Stock HELLA bulb and LED vs. The Honda/Wagner.
Only thing to do after this would be the full LED panel replacement, those may have to wait until after Christmas.
I did take some Daytime photos, the LED bulbs were able to illuminate brighter than direct sunlight on them, unlike the factory bulbs.

those LED's are bright ! i really like them !

Thanks for the update. The Honda bulbs look good too but those LEDs are very bright, wooo. Did you have to change your flasher for the LEDs?

Yes! Two pin with a grounding wire from Amazon ($13). Make sure you double check your polarity at the car side of the pin out. The older flashers didn't care what way the current went, electronic flashers do!
