Looking For LED lights for my 68 Barracuda
Not if you're smart and want to
reduce your likelihood of getting hit in traffic instead of increasing it; nothing that site sells will work safely and effectively in your car's safety (exterior) lights. It's fine if you want to play with their stuff in the interior lamps, because those aren't safety-related.
Instead, clean the front park/turn and rear brake/tail/turn lamp lenses in hot soapy water. If the reflectors are at all dull or peeling, stuff wads of masking tape in the bulb holes (or remove the sockets if they're the removable type), clean the reflectors with alcohol, then spray them with readily available "chrome" spray paint, which is practically ideal for the task.
Then put
these in the brake/tail lights, and
these in the back-up lights.
You will need to swap in
this turn signal flasher (2-prong like original, direct swap)
These recommendations are very specific because they are the only legitimate LED retrofit bulbs. There's a mountain of garbage on the market, too, so use
only these specific LED bulbs. There are not yet any safe LED retrofits for the front park/turn lamps. More info
here.
